Features of water treatment grille decontamination machine

 Water is the most important resource for human survival. Whether it is daily life, industrial development, urban construction, etc., will produce a lot of sewage. If left untreated, water will run out one day. In order to survive the continuation of the recycling and utilization of water resources, in addition to sewage equipment is a must for us. There are three common methods for sewage treatment, which are sieve interception method, gravity separation method and centrifugal separation method. Among them, the most used method is screening and intercepting sewage treatment. For example, the grid clean machine is a representative processing equipment.

 

In grid clean machine, grating is an important collection and drainage equipment. Rainwater screen and drum grille are commonly used. Rainwater screen is a simple and effective technology that can collect and drain a large amount of rainwater to reduce the possibility of flood. It can effectively prevent soil erosion, reduce the entry of pollutants, thus reducing water pollution. In addition, it can effectively collect sewage and direct it to the sewage treatment system. Rain grating is simple in structure. It is composed of a series of horizontal or oblique grooves, whose depth and width can be adjusted according to needs. The bottom of the tank can be covered with sand, gravel, brick and other materials, thus improving the collection efficiency. The construction of rain grating needs to consider many factors, such as terrain, displacement, soil type and building location. It must be built according to professional technical standards to ensure safety and effectiveness.

There are two types of drum grille, namely zg l type drum grille and zg II type drum grille. ZG l type drum grille is a rack and scraper type (spiral) structure, which is a new type of solid-liquid separation environmental protection equipment integrating three functions of grille, transmission machine and screw press. zg i type drum grille is a rack scraper type (spiral) structure, is a new type of solid-liquid separation environmental protection equipment integrating three functions of grille, transmission machine and screw press, can be installed directly in the canal, can also be installed in the container box. Sewage flows in from the front end of the grid basket of the g i type drum grille, flows out from the grid gap, and the filter slag is trapped in the grid basket. The accumulated filter slag on the zg type drum grille forms a filter layer to further filter, thereby improving the filtration efficiency of the zg type drum grille. When the water level difference after the front reaches the set value, the deceleration motor automatically starts, drives the slag rake to rotate, and the slag cleaning teeth extend between the grid bars, and all the filter slag is removed. When the drum grid is rotated to a vertical position, the filter slag automatically falls into the central hopper at the lower end of the screw, is transmitted by the screw, and is pressed at the same time, and finally falls into the material box or the transmission machine for external transport.

zg ll type drum grille is the result of the introduction and digestion of international advanced technology, improvement and innovation, widely used in urban domestic sewage treatment, industrial wastewater treatment, food sewage treatment, paper sewage treatment projects. The decontamination function of the rotary fine grid machine will extract the finer floating matter, suspended matter and sediment in the sewage, and then remove it after transmission and pressing.

zg ll type drum grille Compact design, all parts are made of stainless steel, no high-speed moving parts.

zg ll type drum grille automatic control, smooth operation, low energy consumption, low noise, small rotating grille gap, only 1-5mm, with the help of fluid diversion, equipment separation efficiency of up to 98%, the entire drum type fine grille machine can be self-cleaning during the operation of the equipment. Sand, slag and hard objects non-destructive equipment, no clogging.

 

Grille is an important part of the grille decontamination machine. There are many types of Grille, and we only introduce two widely used ones. Water is a necessary resource for sustainable development, for the sustainable development of human society, recycling sewage, turning waste into treasure, saving water resources, is an important and necessary goal of society.
