Analysis of the principle of each combined equipment of Doyen China sewage treatment zero discharge system.

       Doyen China sewage treatment zero discharge system is a sewage purification and solid waste dry discharge solution designed and built by Doyen for enterprises of beneficiation, sand making, construction and other types with sewage treatment needs. According to the different materials and processing needs of enterprises, the equipment and specific processing technology of enterprises that may process the same kind of materials are different when planning the processing system.

       In many kinds of equipments that make up the zero discharge system, each kind of equipment has its own structure and working principle, which can be applied to the dehydration and pressure drying of different types and granularity materials. In this paper, we will show you the working principle of the common combined equipment of the zero discharge system of sewage treatment in the form of graphics and text, so as to provide you with a simple understanding.

1. Sludge concentration tank of hydrogen purification body

      The three hydrogen purification body sludge concentration tank is a kind of continuous working sludge concentration and clarification equipment. Based on the traditional vertical flow sedimentation equipment, the structure of the internal feed drum is improved, which greatly improves the efficiency of sedimentation. The tank body is circular in plane, and the suspended solids settle into the conical sludge hopper at the bottom of the tank under the action of gravity. The clarified water flows from the overflow weir around the upper end of the tank Discharge. Widely used in aggregate plant, precious metal concentrator, ceramics, glass and other industries.

2. Box filter press

      The chamber filter press uses the pressure difference between the two sides of the filter cloth to force most of the water in the material to pass through the filter cloth and flow out of the machine, while the material is blocked in the filter room to form a filter cake, so as to achieve the purpose of filtration.

3. Belt filter press

      The belt filter press is composed of two tensioned filter belts, which carry the sludge layer and pass through a series of regularly arranged rollers in the shape of S. depending on the tension of the filter belt itself, it forms the pressing and shearing force on the sludge layer, extrudes the capillary water in the sludge layer, and obtains the sludge cake with high solid content, so as to realize the sludge dehydration.

      Doyen specializes in providing belt press equipment for the Southeast Asian market. Welcome to visit our workshop, according to the actual situation of your company, develop a more scientific dehydration program.Welcome to joyce@doyenchina.com or visit https://www.doyenchina.com.
