Concrete mixer is also very important for water control, which is also an aspect of production cost control. Use plenty of water to flush the mixer and cement tank truck every day. It is difficult to deal with after the concrete has set. Therefore, the cleaning process in shutdown is a very expensive project.

而且，这些洗涤设备的洗涤水含有由水泥浆，骨料和骨料携带的杂质，混合 物等。 从环境保护的角度来看，水泥砂浆或混凝土的清洗用水是强碱性的，PH 值高，可达12左右，随机排放会污染环境。 耗水量大的原因在于近年来随着环 保要求的不断提高，混凝土搅拌机的废水处理也成为主要关注点。
             

Moreover, the washing water of these washing equipment contains impurities, mixtures, etc. carried by cement slurry, aggregate and aggregate. From the perspective of environmental protection, the cleaning water for cement mortar or concrete is strongly alkaline, with high pH value, up to about 12. Random discharge will pollute the environment. In recent years, with the continuous improvement of environmental protection requirements, the wastewater treatment of concrete mixer has become a major concern.

事实上，清水洗车也是一大浪费。 假设运输车辆用1-2T水冲洗，每天2-3次 ，中型混合站每天使用20辆车。 例如，每天使用40-120T的水。 从这个角度来 看，洗涤水的再利用非常有利于环境保护和节约用水。

In fact, washing the car with clean water is also a waste. Suppose the transport vehicles are washed with 1-2T water, 2-3 times a day, and the medium mixing station uses 20 vehicles a day. For example, use 40-120t of water per day. From this point of view, the reuse of washing water is very conducive to environmental protection and water saving.
