建筑施工污水对于环境的污染巨大,直接排放的建筑会造成地下水质污染,提出一种集中沉淀和氧化池催化反应的建筑施工污水处理技术,分析建筑施工污水的组成成分,采用接触型氧化池处理技术进行建筑施工污染的沉淀处理,在厌氧调节池中使用Pd基催化剂对建筑施工污水进行碱性中和处理,以微量NaH2PO2作为还原剂,采用合成流变处理技术,有效去除建筑施工污水中的有害物质和杂质.采用该技术进行建筑施工中污水处理,对污染物质的去除率较高,污水处理效率较好.%Construction sewage pollution to the environment is huge and its direct discharge will cause underground water pol-lution. This paper proposed concentrated sedimentation and oxidation pool catalytic reaction construction sewage treatment tech-nology. The composition of construction sewage is analyzed and the sedimentation treatment of construction pollution is carried out by means of contact oxidation tank treatment technology. In the anaerobic regulating tank, PD based catalyst was used to neutral-ize construction sewage, and micro amount of NaH2PO2was used as reducing agent. Synthetic rheological treatment technology was adopted. The experimental results show that using this technology to treat construction sewage has higher removal rate of pol-lutants and better sewage treatment efficiency.
