湛江市赤坎污水处理厂升级改造可行性分析
|
摘要
根据赤坎污水处理厂一、二期现况水质水量数据,确定了升级扩容的规模及水质,并结合现况用地及设施情况,考虑尽可能利用原有土建及设备、减少新增构筑物数量,将现况AAO微曝氧化沟工艺改造为AAO微曝氧化沟+MBBR工艺,并增加了磁混凝澄清池的深度处理设施,为污水处理厂同时升级和扩容提供借鉴和参考。
Based on the water quality and quantity data of the first and second stages of Chikan wastewater treatment plant in Zhanjiang City,the design of capacity scale and influent quality were confirmed.Combining the current situation of land use and facilities,original AAO oxidation ditch craft is ready to be transformed into AAO oxidation ditch+MBBR+magnetic coagulation clarification craft.It provides reference for the similar wastewater treatment plant to upgrade and expand.
