Introduction of wastewater reuse system for spraying industrial wastewater treatment equipment



Introduction of wastewater reuse system for spraying industrial wastewater treatment equipment

The composition of pollutants in coating wastewater is complex (including metal ions, petroleum, pigment, COD, Las, SS, pH, etc.), high concentration, water quality and water quantity fluctuate greatly. The wastewater mainly comes from the pretreatment processes of pre degreasing, degreasing, surface conditioning, phosphating, passivation, etc.; in the cathodic electrophoretic process, intermediate coating and topcoat spraying processes, the automobile coating wastewater contains pollutants such as resin, surfactant, heavy metal ions, pigments, etc., especially the electrophoresis wastewater and painting wastewater, which have complex composition, high concentration and poor biodegradability. Before the treatment of coating wastewater, conventional separation treatment, coagulation sedimentation, coagulation flotation, sand filtration and other processes were mainly used to treat the coating wastewater, which generally contained resin, grease, and benzene (benzene series substances are toxic), and the biochemical ratio is very low, so the conventional treatment process is difficult to meet the standard.

 Spraying industrial wastewater treatment equipment

Source of coating wastewater:

  

Wastewater produced by coating production line of manufacturing related parts and components: furniture factory, paint factory, spraying plant, dye factory, automobile factory, shoe factory, ship, machining plant, etc. This series of products are suitable for the purification and treatment of the sewage produced in the painting line of the ship, automobile, tractor and machinery manufacturing industries. The treated water can be recycled and used for cleaning equipment or flushing floors and toilets.

 Spraying industrial wastewater treatment equipment

Treatment technology of spraying industrial wastewater

1. This product is a complete set of multi machine combination equipment, which is suitable for a wide range of water quality treatment.

2. Compact structure, reasonable operation.

First of all, the surface active agent can be recycled.

Then the sewage enters into the main engine automatically after adding chemicals. The stability of effluent quality is ensured.

5. The new technology that air is directly mixed with water through high-speed jet to produce dissolved air water ensures the effect of air flotation treatment and reduces the load of advanced treatment.

6. The biological oxidation device has the dual functions of biochemical and adsorption, and the filler can be used for a long time without replacement.

Harmfulness of coating wastewater:

Paint mist will be produced in the process of spray painting. In order to make normal production, it is necessary to remove the waste paint mist from the spray booth. The common and effective method is to set water curtain on the side of the spray paint line (i.e. the population of the exhaust duct), so that the water curtain can absorb most of the paint mist, and the waste gas not absorbed by the water curtain agent will be treated with the waste gas treatment method. Due to the different coating process, the source of coating wastewater is different, and the water quality is also different. The coating wastewater belongs to organic industrial wastewater, and the organic pollutants in the water come from the soluble substances in the coating and solvent.

Harm: after coating, the water contains a lot of surfactants and emulsified oil, COD in the water is about 700mg / L, BOD is about 200mg / L, if this kind of water is not treated and directly discharged into the river, a large amount of dissolved oxygen will be consumed when the organic matter in the wastewater is decomposed in the water, which will destroy the oxygen balance in the water body and cause the water quality to produce odor.

    Feedback of evaluation on the use of purchased sewage treatment equipment from Baoji City

    The equipment used for a few days, really good, good quality, low noise, and the price is very cheap, value for money, very satisfied. Customer service was also very good. I'll come back next time when I have the opportunity.

    Application evaluation of chemical wastewater treatment equipment purchased from [Tai'an City]

    The effect of the equipment is very good. I have chemical wastewater here. The local environmental protection department has detected that the pollutant concentration is very high, and they have been worried about the poor treatment. The Fenton + micro electrolysis process designed by the company was half understood and half understood at that time, but after the equipment arrived at the site, the effluent efficiency was improved

    Evaluation of the purchase of aquaculture wastewater treatment equipment from [Hefei city]

    As time goes by quickly, we have been cooperating with China hewogong environmental protection equipment for nearly three years. We are an influential sewage treatment equipment manufacturer. Thank you very much. The service was up to standard
