Role of wedge wire screen in coal mine wastewater pollution


Coal mine sewage is a headache for many enterprises. A large number of harmful substances will be produced in the process of coal mining. If it is not treated in time, it will seriously endanger our health. The wastewater generated by the coal mine industry needs to be treated in time, and at this time, wedge wire screen self-cleaning filters are needed.

According to statistics, the annual discharge of mine water in China reaches 2.2 billion tons, but the reuse rate of mine water resources is only about 20%, which leads to the direct discharge of a large number of untreated coal mine sewage, which not only seriously pollutes the environment, but also wastes the mine water resources of coal mines, which is very unfavorable to China’s development and environment. The self-cleaning filter can not only solve the problem of coal mine sewage discharge, but also protect the environment and save water, killing two birds with one stone.

The waste water pollution source in the coal mining industry has seriously exceeded the standard, which contains a large number of metal ions, which are harmful to human body. If these wastewater is discharged unreasonably, it will cause the blockage of the river, the abnormal production of minerals, seriously affect the water quality and environment, and cause a large number of deaths to organisms in the water. If people accidentally mistake fish or shrimp and other organisms in the water, they can’t imagine the consequences. Therefore, the self-cleaning filter must stand up to solve this problem and give us a clean water source.

Self cleaning filter is a kind of precision equipment that directly intercepts impurities, floating objects and particles in liquid by using wedge wire filter screen, reduces water turbidity and dirt, and ensures the normal operation and service life of rear equipment. It has the characteristics of automatic sewage discharge and effectively solves the problem of sewage quality.

Compared with the traditional filter products, the self-cleaning filter has many disadvantages, such as small pollution capacity, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and the filter state cannot be monitored. It has the function of filtering the raw water and automatically cleaning and discharging the filter element. In addition, the system provides uninterrupted water supply during cleaning and discharging, which can monitor the working state of the filter, and the degree of automation is still very high. The self-cleaning filter covers the requirements of various filtration accuracy from 10um to 3000um, which can completely make the turbid sewage clear.

The self-cleaning filter is not timid in the face of the serious pollution of coal mine wastewater. Instead, it goes forward bravely, which also shows the courage of the self-cleaning filter. It is still capable of solving the pollution problem of coal mine wastewater, making the river no longer muddy and people’s life no longer afraid.
