Abstract

The invention relates to a physicochemical sewage treatment method. In the method, a sewage physicochemical treatment process is added on the existing sewage treatment infrastructure; the capability of treating sewage of the existing infrastructure of a sewage treatment plant is improved; the prior art is upgraded; the sewage is rapidly dephosphorized by adding a dephosphorization agent, an adsorbent and a flocculating agent before treating the sewage in a primary settling tank; nonbiodegradable macromolecular suspended matter in the sewage is flocculated and is rapidly removed by gravitational settling; the settling speed of big floccules is higher than times of the natural settling speed, so the treatment capability of the primary settling tank is also doubled. The method reaches the national discharge standard on the aspects of the main indexes for measuring the treatment effect, i.e. SS (Suspended Solid), COD (Chemical Oxygen Demand), phosphorus content, ammonia-nitrogen content, chromaticity and turbidity, and is a good method for upgrading and reconstructing the old sewage treatment plant.
一种理化污水处理方法,该方法在现有污水处理基础设施上添加污水物化处理工序,增加污水处理厂现有基础设施处理污水的能力,使现有技术升级,通过在初沉池前添加脱磷剂、吸附剂、絮凝剂,快速脱磷,并将污水中难生物降解的大分子悬浮物絮聚,通过重力沉淀快速除去,由于大絮团的沉淀速度大于自然沉淀速度的数倍,初沉池的处理能力也数倍增加。在衡量处理效果的主要指标:SS、COD、含磷量、氨氮含量、色度、浊度方面达到国家排放标准,是对老旧污水处理厂进行升级改造的一个很好方法。
