The diatom original soil is separated from the symbiotic impurities in the selection process and is called diatomite. Since the diatomite is composed of a non-conductive amorphous silica shell and superconducting diatom nanopores, an unbalanced potential is formed on the surface of the diatom. In the sewage treatment, the diatom concentrate treatment agent is added into the sewage in a small amount. Under the high-speed stirring or the pump blade that sucks the sewage, the unbalanced potential of the surface of the diatom can destroy the positive electricity formed by the negative ion nucleus in the sewage. The ion ring, and neutralizing the chargeability of the suspended ions, causes the zeta potential of the colloidal particles and the micelle structure to decrease or be zero, thereby achieving the purpose of detachment of the colloidal particles, and prompting physical flocculation and precipitation of the pollutants in the water. At the same time, the diatom has a large specific surface area, a large pore volume and a strong adsorption force, and the ultrafine particulate matter is adsorbed to the surface of the diatom to form a chain structure, which is instantly separated from the water body. In a special professional equipment, from several meters of water leached slag layer formed of 250 million per gram of diatoms, diatomaceous through nano-pores ultrafiltered effluent suspended solids, bacteria and heavy metal ions such as ultra Fine particles are removed and the water overflows upwards. In addition, the diatom also has its own function of dehydration, which is pressed and dehydrated by a vacuum dehydrator, and the sediment is taken into a cake and taken away, which can be recycled. This equipment is divided into vertical and horizontal structure, used for roughing steel ball blank, high rigidity, The rotation of main shaft and turntable adopt frequency conversion speed regulation;Hydraulic drive pressure, mechanical pressure preservation by compression spring and constant pressure nut locking;Adopt end face bearing with high capacity;The main shaft bearing adopts the mechanical seal structure, which eliminates the hidden danger of the main shaft oil leakage;Horizontal layout, large cycle machining;L type low gravity structure is adopted, and the rotating plate is moving pressurization;Adopt the separate structure of positioning, pressuring and sliding of rolling linear guide rail.The rotation of main shaft and turntable adopt frequency conversion speed regulation;Hydraulic drive pressure, normally open type hydraulic station; Alloy Steel Ball,Ball Flashing Machine,Steel Ball Processing,Horizontal Ball Flashing Xinxiang Sunrise CNC Bearing Equipment Co., Ltd. , https://www.cncsunrise.com
The clean water that meets the national emission standard flows into the biological treatment tank for secondary treatment, then removes residual trace contaminants, and finally passes through the diatom nanoporous ultrafiltration to make the effluent water quality reach the water reuse index stably.
