Brief Introduction</h2><p>To maintain smooth operation of drainage pipe networks, regular dredging is required to remove massive sedimentary waste accumulated inside pipelines. Such waste is collectively defined as sewer pipeline sediment, commonly known as sewer sludge.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">2. Current Status of Sewer Sludge Treatment</h2><p>Sewer sludge refers to deposits collected during drainage pipeline maintenance and dredging. It features complex compositions, being a mixture of domestic waste, muck, gravel, organic sludge and wastewater.If sewer sludge inside urban pipe networks is not cleared timely, it will easily cause poor drainage, urban waterlogging and sewage overflow. Moreover, sedimentary sludge will flow into rivers along with rainwater in rainy days, triggering severe water pollution with massive hazards.As pipeline maintenance gains growing public attention, the output of sewer sludge keeps rising year by year. Storage and disposal of massive sewer sludge have become a tough challenge.The prevailing conventional method is to air-dry dredged sludge on nearby green belts before transporting it to landfills for direct burial. This approach not only pollutes the green space surrounding pipelines, but also faces rejection from landfills. Due to sewer sludge’s complex composition and fluctuating moisture content, most landfills no longer accept raw sewer sludge for direct landfilling.With continuous expansion of urban drainage networks, daily sewer sludge output will surge sharply, further intensifying disposal conflicts. New effective disposal technologies are urgently needed.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">3.

Treatment Solution</h2><p>The dry solids of sewer sludge contain low organic matter, with an average organic content of only 17.2%, while inorganic ash accounts for 82.8%.

Brief Introduction</h2><p>To maintain smooth operation of drainage pipe networks, regular dredging is required to remove massive sedimentary waste accumulated inside pipelines. Such waste is collectively defined as sewer pipeline sediment, commonly known as sewer sludge.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">2. Current Status of Sewer Sludge Treatment</h2><p>Sewer sludge refers to deposits collected during drainage pipeline maintenance and dredging. It features complex compositions, being a mixture of domestic waste, muck, gravel, organic sludge and wastewater.If sewer sludge inside urban pipe networks is not cleared timely, it will easily cause poor drainage, urban waterlogging and sewage overflow. Moreover, sedimentary sludge will flow into rivers along with rainwater in rainy days, triggering severe water pollution with massive hazards.As pipeline maintenance gains growing public attention, the output of sewer sludge keeps rising year by year. Storage and disposal of massive sewer sludge have become a tough challenge.The prevailing conventional method is to air-dry dredged sludge on nearby green belts before transporting it to landfills for direct burial. This approach not only pollutes the green space surrounding pipelines, but also faces rejection from landfills. Due to sewer sludge’s complex composition and fluctuating moisture content, most landfills no longer accept raw sewer sludge for direct landfilling.With continuous expansion of urban drainage networks, daily sewer sludge output will surge sharply, further intensifying disposal conflicts. New effective disposal technologies are urgently needed.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">3.

Brief Introduction</h2><p>To maintain smooth operation of drainage pipe networks, regular dredging is required to remove massive sedimentary waste accumulated inside pipelines. Such waste is collectively defined as sewer pipeline sediment, commonly known as sewer sludge.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">2. Current Status of Sewer Sludge Treatment</h2><p>Sewer sludge refers to deposits collected during drainage pipeline maintenance and dredging. It features complex compositions, being a mixture of domestic waste, muck, gravel, organic sludge and wastewater.If sewer sludge inside urban pipe networks is not cleared timely, it will easily cause poor drainage, urban waterlogging and sewage overflow. Moreover, sedimentary sludge will flow into rivers along with rainwater in rainy days, triggering severe water pollution with massive hazards.As pipeline maintenance gains growing public attention, the output of sewer sludge keeps rising year by year. Storage and disposal of massive sewer sludge have become a tough challenge.The prevailing conventional method is to air-dry dredged sludge on nearby green belts before transporting it to landfills for direct burial. This approach not only pollutes the green space surrounding pipelines, but also faces rejection from landfills. Due to sewer sludge’s complex composition and fluctuating moisture content, most landfills no longer accept raw sewer sludge for direct landfilling.With continuous expansion of urban drainage networks, daily sewer sludge output will surge sharply, further intensifying disposal conflicts. New effective disposal technologies are urgently needed.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">3.

Brief Introduction</h2><p>To maintain smooth operation of drainage pipe networks, regular dredging is required to remove massive sedimentary waste accumulated inside pipelines. Such waste is collectively defined as sewer pipeline sediment, commonly known as sewer sludge.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">2. Current Status of Sewer Sludge Treatment</h2><p>Sewer sludge refers to deposits collected during drainage pipeline maintenance and dredging. It features complex compositions, being a mixture of domestic waste, muck, gravel, organic sludge and wastewater.If sewer sludge inside urban pipe networks is not cleared timely, it will easily cause poor drainage, urban waterlogging and sewage overflow. Moreover, sedimentary sludge will flow into rivers along with rainwater in rainy days, triggering severe water pollution with massive hazards.As pipeline maintenance gains growing public attention, the output of sewer sludge keeps rising year by year. Storage and disposal of massive sewer sludge have become a tough challenge.The prevailing conventional method is to air-dry dredged sludge on nearby green belts before transporting it to landfills for direct burial. This approach not only pollutes the green space surrounding pipelines, but also faces rejection from landfills. Due to sewer sludge’s complex composition and fluctuating moisture content, most landfills no longer accept raw sewer sludge for direct landfilling.With continuous expansion of urban drainage networks, daily sewer sludge output will surge sharply, further intensifying disposal conflicts. New effective disposal technologies are urgently needed.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">3.
