The coating wastewater treatment water treatment cycle is long, especially the anaerobic treatment time generally requires 6-9 hours, and the coagulation sedimentation process takes a long time

Inner Mongolia introduced new technologies for wastewater treatment , developed advanced oxidation technology at a lower cost, and gradually replaced traditional treatment processes. Except for the normal continuous discharge of some overflow water, phosphating, degreasing, electrophoresis, and paint spray baths are all intermittent tank concentration discharges, and the concentration of wastewater tanks or effluent pollutants is higher. Due to various wastewater components, different concentrations, and the characteristics of wastewater discharge at different times, water may change, and some concentrations are high, which has a certain irregular impact on wastewater discharge, resulting in an increase in the drainage of automobile coating lines. Quality change and chance.

It involves degreasing, phosphating, electrophoretic coating, paint and other processes for the pretreatment and passivation of wastewater in the automotive industry and painting workshops, and a large amount of industrial wastewater is produced during the production process. It contains various pollutants, including acids, alkalis, and phosphates. , Mineral oil, surfactants, paints, thinners and other heavy metals, such as COD, heavy metals, a wide variety, poor biochemical properties, and it is difficult to ignore the degree of pollution and toxicity. There are still many problems with the construction of wastewater treatment plants for automobile plants. The first is the issue of funds. The construction of a coating wastewater treatment station requires a large amount of capital investment; technical aspects: the initial commissioning and operation of the coating wastewater treatment station requires very professional personnel; the operation problem of the wastewater treatment in Inner Mongolia : the operating cost of the coating wastewater treatment.

The size of the ENT station is large, and if it cannot be managed effectively, it will cause problems such as cost waste. From the perspective of protecting water resources and the environment, give full play to the social, environmental and economic benefits of construction projects. Need to start from the following aspects. Adopt high-efficiency, energy-saving, stable and reliable processing technology and equipment to ensure that the water quality meets national requirements; engineering operation costs should be one of the important principles in the selection of technical solutions. The equipment is selected based on the principles of high efficiency, energy saving, reliability, and easy maintenance. The process operation effect is reduced, and the operation and maintenance costs are reduced. The monitoring instrument and automation technology suitable for the national conditions are used for easy operation and management. The area occupied by the processing technology should be considered. Small and efficient operation. On the premise of satisfying the construction, installation and maintenance, the structure should be concentrated as much as possible to save the floor space.

The coating wastewater treatment system uses a reliable control system, which is simple to operate and easy to maintain. Improve the automation level of sewage treatment stations. Although water is usually clear scum, it can be recycled after (or sediment), but there must be two things: it is part of the water that is discharged as waste water, adding a lot of fresh water and water; the second is water The curtain water goes through a cycle. ER uses all updates. This very high and highly toxic water curtain water is dangerous to humans if it is not treated directly in rivers (lakes) and must therefore be treated. Due to the high concentration of pollutants in the waste liquid, the discharge volume is unstable, and the discharge time is not fixed, the waste liquid should not be directly discharged into the automatic control sewage treatment tank. Inner Mongolia wastewater treatment We divide waste liquid into inorganic and organic secondary treatment, and perform pretreatment separately.
