摘要:

针对我国西南地区广大乡镇农村污水处理建设过程中出现的进水浓度高，水量波动显著等问题，设计一种改良型AAO+MBBR一体化处理装置。该装置抗进水冲击负荷强、占地小、工艺运行成本低等特点，适用于西南丘陵地区农村分散居住的特点。连续运行监测结果表明，对CODcr、BOD5、TP、NH3-H、SS去除率分别达到88%、96%、83%、83.3%、77.8%，出水水质指标满足《城镇污水处理厂污染物排放标准》（GB18918-2002）一级A标准

Abstract:

Aiming?at?the?problems?of?high?influent?concentration?and?significant?fluctuation?of?water?quantity?in?the?process?of?sewage?treatment?construction?in?rural?villages?and?towns?in?southwest?China,?an?improved?AAO+MBBR?integrated?treatment?device?was?designed. The device has the characteristics of strong resistance to water impact load, small land occupation, low process operation cost, etc., and is suitable for scattered living in rural areas in southwest hilly areas. The continuous monitoring results show that the removal rates of CODcr, BOD5, TP, NH3-H and SS are 88%, 96%, 83%, 83.3% and 77.8%, respectively, and the effluent quality index meets the first-class A standard of Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002).
