Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people.

The grid sewage removing machine is the first procedure of sewage treatment technology, also is one of the equipment that breaks down in the sewage treatment plant most easily, and in case break down, sewage treatment plant will not normally intake, and its problem that often appears has: 1. blocking of the grating machine: whether the grid machine runs continuously or intermittently, because the grid machine power device is contacted with sewage for a long time, abrasion is easy to cause, the running blockage phenomenon is easy to cause, and a chain or rake teeth are deflected or other mechanical faults are easy to cause; 2. blocking the grating machine: the sewage is often carried with long-strip-shaped fibers, plastic bags and other sundries which are easy to wind, and the grid bars, rake teeth and the like are easy to block. On the one hand, the section of the passing grid is reduced, the flow velocity of the passing grid is too high, and the trash blocking efficiency is reduced. On the other hand, the problems of slow water passing rate of the grid channel, sand deposition, overflow of the grid channel and the like can also be caused. At present these problems generally can only be carried out technical transformation perfect or the maintenance of working, adopt the mode of artifical clearance to solve, it is very consuming time hard, sewage filters with high costs, the filter effect also can receive the influence, general improvement device is like CN110026004A, does not solve above-mentioned problem, for this reason, we propose one kind and be difficult for by wearing and tearing corruption, concentrate pollutants such as big and small fibre, plastic bag, the clearance of being convenient for, the filter effect is good, the prevention blocks up and long service life's sewage filter equipment.
