Petrochemical wastewater treatment system

Abstract

The invention discloses a petrochemical wastewater treatment system. The system comprises a PH regulating tank, wherein an aeration tank and a disinfection tank, a liquid inlet hopper, a flocculatingagent feeding opening and a stirring motor are arranged above the PH adjusting tank; a first high-pressure pump is arranged on one side of the PH adjusting tank; the water pumping end of the first high-pressure pump is communicated with the inner cavity of the PH adjusting tank through a water pipe, and the water outlet end of the first high-pressure pump is communicated with the aeration tank through a water pipe; an aeration pump is arranged at the bottom of the aeration tank; and an oil scraping assembly is arranged above the inner cavity of the aeration tank; a second high-pressure pump isarranged on the outer side of the aeration tank, the water pumping end of the second high-pressure pump is communicated with the bottom of the aeration tank through a water pipe, the water outlet endof the second high-pressure pump is communicated with the disinfection tank through a water pipe, a disinfectant feeding opening is formed in the upper portion of the disinfection tank, a purified water outlet is formed in the lower portion of the disinfection tank, and a drain valve is arranged on the purified water outlet. Compared with like systems in the prior art, the wastewater treatment system of the invention has the advantages that wastewater can be subjected to multi-stage filtration treatment, and oil stains and harmful substances in the wastewater can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a petrochemical wastewater treatment system. Background technique [0002] The petrochemical industry is an important part of the chemical industry. It plays an important role in the development of the national economy and is one of the industrial pillars of our country. However, a large amount of sewage will be generated in the petrochemical industry. If the sewage produced cannot be effectively treated, it will not only cause It causes serious pollution to the environment, and cannot be recycled and reused, resulting in excessive waste of water resources. Therefore, a complete sewage treatment and reuse system is an indispensable and important facility in the petrochemical industry. However, in the chemical industry, the design of sewage treatment methods is still not perfect, resulting in ineffective filtration and inability to completely remove impurities, oil an...

[0002] The petrochemical industry is an important part of the chemical industry. It plays an important role in the development of the national economy and is one of the industrial pillars of our country. However, a large amount of sewage will be generated in the petrochemical industry. If the sewage produced cannot be effectively treated, it will not only cause It causes serious pollution to the environment, and cannot be recycled and reused, resulting in excessive waste of water resources. Therefore, a complete sewage treatment and reuse system is an indispensable and important facility in the petrochemical industry.

However, in the chemical industry, the design of sewage treatment methods is still not perfect, resulting in ineffective filtration and inability to completely remove impurities, oil and other harmful substances in sewage, resulting in substandard sewage purification and treatment quality.
