Problems solved by technology

Such as oily additives, extreme pressure additives, anti-rust additives, anti-foam additives, and anti-mildew additives, which make the composition of the emulsion more complex and more difficult to handle
Therefore, it is difficult to meet the emission requirements by using one method alone, and several process combinations are required to meet the standards.
[0004] At present, the treatment of emulsion wastewater is mainly based on chemical treatment, supplemented by biochemical reactions, with low technical level and high operating costs, and it is basically difficult to meet the discharge standards.
Even if some discharges meet the standards, they are basically mixed with other easily treated wastewater and diluted for treatment. The main reasons are: 1. The emulsion contains high concentrations of organic matter that is not easy to biodegrade. Using advanced ox

Abstract

The invention provides a novel emulsion wastewater treatment process. The process comprises a regulating reservoir, an accident pool, a demulsification device, a paper strip filter, a ceramic film filter, an ozonolysis tank, a hydrolysis acidification pool, an aeration tank, a settling pond, a quartz sand filter and a water discharge pool. Aiming at the characteristics of emulsion water quality, physicochemical treatment units and biological treatment units are reasonably combined, and the process has the advantages of short and compact process procedures, high treatment efficiency, low energy consumption, long service life of a film component and the like.

Description

Technical field [0001] The invention relates to the technical field of water treatment, in particular to a process method for treating emulsion wastewater. Background technique [0002] Emulsions are widely used in mechanical processing, automobile engine processing, cooling and lubrication of rolls and steel plates. Because of the influence of environmental media, it is easy to age and deteriorate, so it needs to be replaced regularly. The chemical properties of the replaced emulsion wastewater are extremely stable. The wastewater contains high concentration of oil and high concentration of organic matter. Therefore, the emulsion wastewater is difficult to treat and is easy to treat. The environment causes serious pollution. [0003] Emulsion wastewater treatment methods include physical and chemical methods and biochemical methods. Specifically, chemical coagulation method, co-coagulation air flotation method, electrocoagulation method, advanced oxidation method, ultrafiltratio...
