Problems solved by technology

[0002] With the rapid development of industrialization and urbanization in our country, the discharge of industrial wastewater is increasing. Industrial wastewater often contains a large amount of harmful substances such as heavy metal ions, inorganic compounds and organic compounds, such as Cr, Ni, phosphate, ammonia nitrogen compounds, Organic acids, etc., if the treatment is not up to standard, these substances will definitely cause extensive and serious harm to the ecological environment and human beings when they enter the environment, and they will even accumulate in organisms through the food chain, breathing or direct contact. If the concentration of heavy metal ions, inorganic compounds and organic compounds in the treated wastewater is only close to the discharge standard, it will cause the industrial wastewater treatment to be discharged directly and cannot be reused. This will cause a great waste of water resources, which does not meet the requirements of sustainable development

Abstract

The invention discloses an industrial wastewater treatment method, comprising the following steps: pretreatment, secondary treatment and advanced treatment of industrial wastewater, wherein the pretreatment of industrial wastewater comprises homogenization, filtration and biosorption, and the secondary treatment is a combination of anaerobic and aerobic treatments, and comprises hydrolysis acidification, anaerobic digestion, and aerobic biochemistry; the advanced treatment comprises a filler adsorption tower, and various indicators of wastewater treated are up to standard. The pretreatment process of the industrial wastewater treatment method disclosed by the invention effectively removes a large amount of suspended solids, sediments and heavy metal ions in the industrial wastewater, the secondary treatment process effectively removes inorganic substances, organic pollutants, nitrogen and phosphorus and other nutrients in the wastewater, and the advanced treatment strengthens the denitrification effect on the basis of further removing organic pollutants; after the wastewater is treated by the method disclosed by the invention, various indicators of the effluent all meet the first-level standard in the Integrated Wastewater Discharge Standard (GB8978-1996), and can be reused in industrial production.

Description

Technical field [0001] The invention belongs to the technical field of wastewater treatment, and specifically relates to an industrial wastewater treatment method. Background technique [0002] With the rapid development of China’s industrialization and urbanization, the discharge of industrial wastewater is increasing. Industrial wastewater often contains a large number of harmful substances such as heavy metal ions, inorganic compounds and organic compounds, such as Cr, Ni, phosphate, ammonia nitrogen compounds, Organic acids, etc., if the treatment is not up to standard, these substances entering the environment will inevitably cause extensive and serious harm to the ecological environment and humans, and even accumulate in organisms through the food chain, respiration, or direct contact pathways, which is harmful to organisms and humans. Health is a threat, and in severe cases it may even cause genetic mutations or induce cancer; and if the concentration of heavy metal ions, ...
