白龙港污水厂污泥深度脱水设施的设计与试运行

摘要

上海市白龙港污水厂污泥深度脱水设施设计规模1500 t/d（以含水率80％计），采用三氯化铁、石灰化学调理和隔膜压滤处理工艺，经深度脱水后的污泥含水率小于60％。工程于2012年6月基本建成，7月起开始调试。通过4个月调试运行，污泥处理能力稳定达到300 tDS/d的设计规模，压滤机出泥泥饼含水率控制在60％以下，满足设计要求。%The designed scale of sludge deep dewatering facilities in Shanghai Bailonggang Wastewater Treatment Plant is 1 500 t/d (moisture content is 80%). After FeCl3 and lime added and treatment process of diaphragm filter press used,the moisture content of sludge which treated by deep dewatering is less than 60%. The project was basically completed in June 2012 and was already tested from July to November in 2012. During 4-month commissioning operation time,the ability of sludge treatment was stable and reached 300 tDS/d. The moisture content of treated sludge was lower than 60%,which met the design requirements.
