摘要
采用污泥深度脱水技术,可使泥饼含水率降到40%～55%,有利于污泥后续处置的同时实现全过程的COD减排及碳减排。经核算,10万m3/d污水处理厂产生的污泥经深度脱水-焚烧、深度脱水-填埋工艺进行合理有效的处理处置,COD日排放均可减少5.52 t,CO2日排放可分别减少26.06 t和5.61 t。
Sludge deep dewatering process can lower the water content of sludge cakes to 40%-55%, which is conductive to subsequent sludge disposal while reducing COD and carbon emissions. For the sewage sludge from a wastewater treatment plant with the capacity of 100 000 m3/d, COD emission can be reduced by 5.52 t/d and CO2 emission can be reduced by 26. 06 t/d and 5. 61 t/d, respectively, after effective treatment and disposal by deep dewatering-incineration process and deep dewatering-landfill process.
