The invention discloses a wastewater treatment device and a treatment method thereof, car washing wastewater is collected in a collection tank and then enters a flocculation tank to be subjected to a flocculation reaction with a flocculant, insoluble impurities in the wastewater form flocculent sludge in the process, the flocculent sludge is precipitated under the action of gravity after the wastewater enters a precipitation tank, mud and water are separated, and the wastewater is discharged from a discharge port. After the wastewater is subjected to flocculation and precipitation, most of insoluble impurities in the wastewater are removed, the residual insoluble impurities in the wastewater are filtered out through the filter assembly, and soluble organic pollutants such as oil emulsion, organic matters and detergents in the wastewater are oxidized and removed through the electrode treatment assembly, so that the wastewater reaches the standard of reuse water after being treated. The device disclosed by the invention can be used for carrying out innocent treatment on the car washing wastewater containing pollutants such as a surfactant, ammonia nitrogen, CODCr, BOD5 and total phosphorus, the turbidity of effluent treated by the device is less than or equal to 1NTU, and the cyclic utilization of water resources is realized.

    本发明公开了一种废水处理装置及其处理方法,洗车废水在收集池收集后进入絮凝池与絮凝剂发生絮凝反应,废水中的难溶性杂质在此过程中形成絮状污泥,进入沉淀池后絮状污泥在重力作用下沉淀,泥水分离,经过絮凝沉淀后废水中大部分难溶杂质被去除,再通过过滤器组件,将废水中剩余的难溶杂质滤除,再通过电极处理组件,将废水中的可溶性有机污染物,如油乳化液、有机物及洗涤剂类氧化去除,使废水经处理后达到回用水标准。本发明的装置能够对含有表面活性剂、氨氮、CODCr、BOD5、总磷等污染物洗车废水进行无害化处理,通过本装置处理后出水的浊度≤1NTU,实现水资源循环利用。
