Description
Technical field
The present invention relates to sewage water recovery purifying processing unit, more particularly to a kind of carwash that water-saving and emission-reducing can be recycled are dirty
Water Sproading purifier.
Background technology
At present, with the fast development and the continuous improvement of living standards of the people of Chinese society economy, China's automobile is possessed
Amount maintains sustained and rapid growth, the data announced according to Traffic Administration Bureau of the Ministry of Public Security, by the end of the year 2015, and China's vehicle guaranteeding organic quantity is up to 2.79 hundred million
, wherein 1.72 hundred million, automobile.While China's automobile process is constantly accelerated, a large amount of of car washing water certainly will be also brought to disappear
The problem of consumption.According to statistics, 1 each cleaning water consumption of compact car is about 0.15~0.20m3, 1 annual carwash in big and medium-sized cities disappears
The tens of thousands of people of water consumption enough ten are used for 1 year.In addition, many city car-washing rows are nearly all with the direct carwash of running water, it is most of
Non- necessary water saving and cycling use of water facility, environmental protection facility are simple and crude, and a large amount of car-washing sewages are just directly discharged into river course without processing, much
Do not reach the secondary discharge standard of national regulation, thus car-washing sewage is again into another source of water pollution.And current shifting
Dynamic carwash service wastes big there is also car washing water, and car-washing sewage is allowed to crossing current, and car-washing sewage recovery utilization rate is low, pollutes ring
The shortcomings of border, destruction urban.Current and the water shortage problem of China becomes increasingly conspicuous from now on, water pollution is aggravated increasingly, therefore, section
About car washing water, reduction carwash water pollution are urgent problems.
