Submersible sewage pump for industrial wastewater treatment
With the development of petroleum and chemical technology, people gradually realize that, some of the production process of water quality demand is not high, the other processes in the sewage can and fresh water are mixed in a certain proportion, as the process of water. Then, along with the progress of water treatment technology, people found that some drainage process water is complex and difficult to deal with, and other water quality of drainage process simple, according to the different water quality of sewage treatment alone, than will the sewage mixed in with more economical.
Petroleum and chemical industry is a series of organic compounds in the process of oil as raw material, such as cracking, refining, fractionation, reforming and synthesis. The production process of petroleum and chemical products is long, the production equipment is much, the amount of sewage produced is big, the typical petrochemical sewage contains oil, CODCr, ammonia nitrogen, sulfur, phenol, cyanide and other conventional pollutants. At the same time, enterprises of different due to different products generated wastewater also contains various and organic chemical products related to the characteristics of pollutants, such as polycyclic aromatic hydrocarbons, aromatic amine compounds, heterocyclic compounds, resulting in sewage is not only a complicated water quality and toxic substances. In addition, the company's open parking, maintenance, changes in raw materials, such as the source of the fluctuations in the production of sewage and pollutants will cause the content and nature of the changes, increased the impact load of sewage treatment facilities.
