气浮+水解酸化—接触氧化处理高速公路服务区污水

Treatment of sewage in expressway service zone by air floatation and hydrolytic acidification-contact oxidation process

介绍了气浮+水解酸化—接触氧化工艺处理高速公路服务区生活污水、含油废水的成功工程实例。该工艺替代了高速公路服务区较为普遍采用的WSZ地埋式污水处理设备,解决了设备腐蚀及停留时间不足等问题。同时也为该行业的废水处理提供了工艺选择方面的参考。

A successful engineering example of domestic sewage and oil-bearing wastewater treatment process in expressway service center by floatation and hydrolytic acidification -contact oxidation is presented. This process substitutes the WSZ wastewater-processing machine that is generally used in expressway service center, and also resolves the problems such as the corrosion of equipments and shortage of HRT. Meanwhile, some references to wastewater treatment in this field are provided.
