Sewage treatment in Expressway service area

Flat ceramic membrane technology

Why is the flat ceramic membrane water treatment technology favored in the construction of Expressway sewage treatment?

Atypical domestic sewage

Firstly, let's look at the sewage source of the expressway service area: the main components of the expressway service area facilities include accommodation, supermarkets, catering, leisure and entertainment, gas, car repair and other functions. In addition to routine domestic sewage, sewage from service stations also includes oily sewage and flushing sewage from gas stations, restaurants and automobile repair plants. The main pollution factors are petroleum, COD, BOD, SS and so on. Therefore, sewage treatment is more difficult than typical domestic sewage.

Reuse of wastewater

Secondly, the expressway service area is far away from the city, scattered layout, and then the sewage cannot be discharged into the municipal sewage treatment system. If the wastewater is directly discharged without treatment, it will cause damage to the surrounding ecological environment. Meanwhile, some the high-speed service area municipal water supply is insufficient. They need self-prepared water to supplement. But the flushing, greening water recycling needs large amount. Therefore, waste water recycling is particularly important. In view of the above characteristics of sewage, O/A/O + flocculation + flat ceramic membrane ultrafiltration system + ozone disinfection can be effectively solved.
