Pressolution electrolytic pressolution biochemical multifunctional air-float complete sets of equipment

Abstract

The multifunctional air-floating complete set equipment integrates several water-treatment functions of electrochemical oxidation-reduction, electric physicochemical flocculation, pressure-solvation biochemical treatment and solid-liquid separation into one body. By adopting the basic principle of physico-chemical and bio-chemical linear combination the organic sewage is electrochemially and physicochemically pretreated firstly, then undergone the process of high-effective pressure solvation biochemical treatment, finally is electrochemically and physicochemically treated, and clear water and concentrated dross are respectively and continuously discharged. Said invention is suitable for treating various industrial sewages and city sewage.

Description

technical field [0001] The invention discloses a novel organic pollution wastewater treatment technology process system - "pressure-dissolving electrolysis pressure-dissolving biochemical air flotation complete set device". The device adopts the principle of linear combination of electrochemical physicochemical method and biochemical method, has multiple water treatment functions and excellent comprehensive performance, and is suitable for one-step treatment of many industrial sewage to meet the standard discharge; The one-step treatment after anaerobic treatment reaches the standard discharge; it is suitable for the one-step treatment of urban comprehensive sewage and meets the standard discharge. Background technique [0002] The more advanced technology of using air flotation device to treat organic polluted wastewater is "Comprehensive Air Flotation Device for Pressure Dissolution and Electrolysis", and its patent application number is: 98112775·4. The principle of the ...

Problems solved by technology

At this time, physical and chemical treatment should not be used, but biochemical treatment should be used to be more economical, but this will cause the entire project to be complicated, occupy more land, and be inconvenient to manage. Although the operating cost is much lower, the investment will increase correspondingly. , it is not cost-effective, there is no way, only to materialize to the end

At present, there are more than 300 industrial sewage treatment projects in the Huaihe River Basin in my country. The physical and chemical process is used to treat the discharge in one step to meet the discharge standards, but the operating costs are unbearable. They only operate during the day and do not add chemicals at night, which is a project failure.

[0018] "Piezolytic electrolysis comprehensive air flotation complete set" and the electrochemical oxidation, reduction, and electrophysiological flocculation technology contained in it have greatly improved compared with ordinary physical and chemical methods, greatly reducing operating costs and ensuring that the effluent water quality is up to standard, expanding The scope of application is widened, the sludge output is reduced, etc., but the removal rate of polar organic molecules that are easy to biochemically in organic sewage is still low, because the "Comprehensive Air Floatation Device for Pressure-solution Electrolysis" has no biochemical treatment function
