This sewage treatment equipment is actually very simple, that is, recycling car wash sewage and recycling it. After treatment, the car washing sewage can be reused for car washing, and it can also reach the standard of direct drinking. There are usually large car wash shops. You can find a familiar car wash shop to stroll around. Although I don't wash the car here, I have such equipment. Welcome to visit. Yes, Hi me or q me 10 10886882.
