Now, the sewage pump already in high-rise buildings, residential sewage station, wastewater discharge enterprises and other places have a pump is indispensable. At present, pretreatment of industrial wastewater treatment is mainly to improve the water quality, the removal of suspended solids and direct deposition of impurities, regulating water water quality and water temperature reducing waste, improving wastewater treatment effect, ensure the stability of the whole system, because this pretreatment plays an important role in the treatment of printing and dyeing wastewater in.
The pretreatment technique for dyeing wastewater treatment mainly includes: grille, screen, sand, water and water quality adjusting cooling process. According to different printing and dyeing wastewater treatment, different pretreatment methods are adopted to remove some of the pollutants, and improve the treatment effect of wastewater treatment units.
In recent years, the development and application of a variety of new materials is an important factor to promote the development of pump technology. The pump parts adopt a variety of new materials, the benefits of the main is to extend the pump in the corrosive medium of service life and reliability, and expand the scope of the use of the pump. In order to meet the needs of different conditions and uses, the product is bound to expand the product specifications, expand the scope of the development of performance.
