摘要:
杭州城西污水处理厂按照浙江省《城镇污水处理厂主要水污染物排放标准》（DB 33/2169—2018）进行技术改造，将原一期生物池AAO处理工艺改造成Bardenpho+MBBR工艺，同时增加了低温带式干化污泥深度处理设施。改造完成后出水水质稳定达到设计标准，干化出泥含水率可降至30%左右，但也出现了MBBR填料偶发性堵塞、干化车间臭气浓度高、产泥量提升难度大等问题，值得同类污水厂升级改造时注意。
Abstract:
Hangzhou Chengxi wastewater treatment plant was reconstructed technically in accordance with the Discharge Standard of Major Water Pollutants for Municipal Wastewater Treatment Plant (DB 33/2169-2018) in Zhejiang Province. The original biological tank AAO treatment process in phase I is transformed into Bardenpho and MBBR process, and the advanced treatment facilities of low temperature belt drying sludge are added. After the transformation, the effluent can reach the design standard stably, and the water content of dried sludge can be reduced to about 30%. However, there are also some problems, such as the occasional blockage of MBBR filler, high odor concentration in drying workshop and difficulty to improve sludge production, which can provide reference for the upgrading and reconstruction of similar WWTPs.
