一体化氧化沟处理污水的试验

Using Interchannel Clarifier Oxidation Ditch to Treat Wastewater

本文设计开发了一种新型的一体化氧化沟系统,对共进行了清水模拟试验和污水处理试验。 清水试验结果表明,这种一体化氧化沟沟内沉淀池具有,良好的固液分离特性,当水力停留时间大于12小时,沟内SS在2～5e/1时,出水SS均小于50mg/1,出水SS相对于沟内SS的去除率大于98％。 污水试验结果表明,系统有较强的去除有机物的能力,当水力停团时间为21小时时,COD去除率可达80％以上,BOD_6去除率在90％以上。出水水质达到了国家排放标准。

A new type of interchannel ciarifier oxidation ditch system was designed and developed. And simulation test with tap water and wastewater treatment experiment was conducted.The results from the tap test showed that the new interchannel clarifier has good performance on the solid-liquid separation. When HRT was longer than 12 hours and SS in the ditch was 2-5g/l,SS in the effluent would be less than 50 mg/l,The SS removal efficiency was more than 98% with,the SS concentration in effluent compared with the SS concentration in the ditch.The results from the wastev. ate experiment showed that the new system has a higher capacity of the organic removal. When HRT was 21 hours,COD,BOD removal efficiency were above 80% and above 90%,respectively, The effluent quality has met the national discharge standard.
