Problems solved by technology

[0004] 1. Most of the sewage treatment equipment is relatively large and requires supporting projects. This is inseparable from a large area of ​​the site and also requires a large amount of financial support. It is aimed at the sewage treatment of large and medium-sized enterprises or centralized sewage treatment, thus limiting the effluent treatment of many SMEs
2. Although there are a few sewage treatment equipment that can change the sewage treatment problems of small and medium-sized enterprises, they can directly turn sewage into clean water, but these equipment are inseparable from backwashing and must discharge backwashing water; discharge liquid sludge; discharge filth Turbid water, thus leaving a lot of sequelae to the environmental protection
3. Although there are very few equipments that do not have the first two disadvantages, they can only treat sewage with moderate amounts of elements and magnetic pollutants in the water, which also limits the treatment capacity and effect of sewage, even the same kind of sewage But as long as the content is different, the treatment effect will be greatly affected
[0009] 1. The purified water after treatment is not as clear and transparent as tap water. There are suspended solids and car wash liquid foam in the water, which will leave traces after cleaning the car; 2. The purified water cannot be reused multiple times, and it will become cloudy after repeated use It will deteriorate and stink, and the peculiar smell will remain after cleaning the car; 3. The blockage of mud slag makes the backwashing of the filter element very troublesome, and it will gradually shorten the backwashing interval and cause more frequent backwashing; 4. The backwashing water The impact will cause friction and consumption of the filter element material, which will increase the cost of use
In addition to these major defects, "car wash sewage treatment equipment" also has two adverse consequences of use:
[0010] 1. The concentrated sludge water and backwash water after sewage treatment should be discharged from the equipment and flow into the sewer pipe, which will cause secondary pollution
Treating sewage protects the environment, but discharging sewage and sludge water pollutes the environment
2. The "circulating water equipment" that was originally used to treat sewage, but in turn, flushes the "circulating water equipment" with a large amount of purified water and discharges it, which changes the performance of the equipment and still wastes water
Therefore, the promotion of "circulating water equipment" is very difficult

Embodiment 1

[0024]Dirty water enters the equipment through the blade pulverizer and enters the No. 1 filter dehydration separator between 4 mesh and 100 mesh. The cake comes out of the equipment and packed in bags. The sewage separated by the No. 1 filter dehydration separator enters the No. 1 sewage tank through the dosing device. The No. 1 sewage tank is higher than the sedimentation reaction device, so that the sewage produces a drop into the sedimentation reaction device with a large upper part and a smaller one at the lower part. The dosing sewage enters from the water inlet hole in the middle part of the sedimentation reaction tank in a rotating manner, so that the sewage rotates downwards faster. To form a centripetal force to promote the sedimentation and concentration of sludge. When the clear water overflows from the top edge of the sedimentation reaction tank to the overflow tank, the siphon connected to the outlet at the bottom of the precipitation reaction tank will produce ...

Embodiment 2

[0026] The No. 1 sewage tank is higher than the sedimentation reaction device, so that the sewage has a drop and enters the sedimentation reaction device, which is small at the bottom and large at the top. Centrifugal force is formed to separate clean water. When the clean water rises to the vertical small hole through the sewage interceptor, part of the clean water will flow into the ring groove from the vertical small hole, so that the speed of clean water rising to the top of the reaction barrel will be slower, prolonging the interval time of the siphon phenomenon in the siphon tube, which is conducive to the reaction The sludge at the lower end of the bucket is coagulated and concentrated. Clean water flows into the ring groove from the vertical small hole and the top edge of the reaction tank, and then enters the filter device through the water outlet hole. After the water enters from the lower part of the filter device, it pushes the lower screen to move, and the filter ...
