Environment-friendly chemical engineering sewage treatment equipment

Abstract

The invention discloses environment-friendly chemical engineering sewage treatment equipment, and belongs to the field of chemical engineering sewage treatment. The environment-friendly chemical engineering sewage treatment equipment comprises a water inlet pipe, a coarse filtering pool, a fine filtering pool, an anaerobic pool, a first anoxic pool, an aerobic pool, a second anoxic pool, a membrane pool and a water outlet pipe, wherein the coarse filtering pool, the fine filtering pool, the anaerobic pool, the first anoxic pool, the aerobic pool, the second anoxic pool, the membrane pool and the water outlet pipe are sequentially communicated; the fine filtering pool is a vertical filtering pipeline; a filtering screen is rotationally connected in the pipeline; the upper end of the filtering screen is communicated with a back flushing device; an ultraviolet sterilization device is arranged in the water outlet pipe; the ultraviolet sterilization device consists of a solar panel, a storage battery and an ultraviolet sterilization lamp. Sewage is subjected to a series of sewage treatment processes, so that the comprehensive purification treatment on the sewage is realized; the sewagepurification degree is improved.

Description

technical field [0001] The invention relates to the field of chemical sewage treatment, and more specifically relates to an environment-friendly chemical sewage treatment equipment. Background technique [0002] The function of the aerobic pool is to allow the activated sludge to perform aerobic respiration, further decompose the organic matter into inorganic matter, and remove the pollutants. The function of the aerobic pool is to control the oxygen content and other requirements of the microorganisms. Only when microorganisms can perform aerobic respiration with the greatest benefit; anaerobic treatment uses the action of anaerobic bacteria to remove organic matter in wastewater, which usually takes a long time. The anaerobic process can be divided into hydrolysis stage, acidification stage and methanation stage ; [0003] The anoxic pool is relatively anaerobic and aerobic, and generally refers to a biochemical system in which the dissolved oxygen is controlled between 0...

AI Technical Summary

Problems solved by technology

[0004] 1. The composition of chemical wastewater is complex, and the reaction raw materials are often solvent substances or compounds with a ring structure, which increases the difficulty of wastewater treatment; 2. The wastewater contains a large number of pollutants, mainly due to incomplete reaction of raw materials and raw materials or production. 3. There are many toxic and harmful substances. Many organic pollutants in fine chemical wastewater are toxic and harmful to microorganisms, such as halogen compounds, nitro compounds, dispersants or surfactants with bactericidal effects, etc.; 4. There are many biodegradable substances, low BOD / COD, and poor biodegradability; the wastewater generated in the production process of chemical products is characterized by large discharge, high toxicity, high concentration of organic matter, high salt content, high chroma, and refractory degradation The content of compounds is high and the treatment is difficult, but at the same time, wastewater also contains many available resources. As a high-tech, membrane technology plays an important role in the production and processing, energy saving and clean production of the chemical industry.
