钱江污水厂处理方法综述
[摘要]萧山钱江污水处理厂一期工程设计规模120000m3/d，采用高校生物反应器工艺，二期工程设计规模120000m3/d。随着萧山城市规模的不断扩大及经济的不断发展，污水量迅速增加，目前，一、二期工程已满负荷运行。为缓解萧山钱江污水处理厂的运行压力，进一步改善钱塘江水体环境，钱江污水处理厂出水水质需达到《城镇污水处理厂污染物排放标准》（GB18918-2002）一级A标准，因此，该污水厂的三期扩建及一、二期提标改造工程迫在眉睫。

Methods Review of WWTP in QIANJIANG City
Abstract：The design scale of the first phase of XiaoShan QianJiang sewage treatment plant is 120000m3/d, and the bioreactor technology of colleges and universities is adopted. The design scale of the second phase is 120000m3/d. With the continuous expansion of XiaoShan city scale and the continuous development of economy, the amount of sewage increases rapidly. In order to alleviate the operational pressure of XiaoShan QianJiang sewage treatment plant and further improve the water environment of QianTang river, the effluent quality of QianJiang sewage treatment plant needs to meet the 'urban sewage treatment plant pollutant discharge standard' (GB18918-2002) level A standard. Therefore, the phase Ⅲ expansion of the sewage plant and the phase I and Ⅱ bid upgrading project are extremely urgent.
