Car Wash Wastewater Treatment Equipment Car wash sewage treatment is an important issue, and here are some of the treatment methods:
Catalytic oxidation (including photocatalytic oxidation): This is a complete ** treatment process, including pretreatment, flocculation separation and photocatalytic oxidation. First of all, the sewage flows into the original ** sedimentation tank of the car wash for grit and oil separation. Then enter the collection tank and carry out a flocculation reaction to flocculate and remove pollutants such as car wash sewage and sediment, and the separated water is clear and transparent. Next, under the action of ultraviolet light and nano photocatalysts, the residual pollutants in the water are oxidized and degraded, and the pollutants that cause water odor are completely eliminated. This method has low operating costs and low maintenance costs.
Quartz sand filtration Activated carbon adsorption multi-media filter: This method lacks secondary treatment, and the water quality of the car wash is easy to clog the filter, once the filter is saturated, the equipment will be paralyzed and unusable, and the cost of frequent replacement is high. In addition, the quality of the treated water cannot meet the water quality standards for car wash water reuse.
Biochemical method and biofilm method: The nutrients of car wash water are not enough to meet the biochemical requirements, and certain artificial measures need to be taken to add nutrients. However, long-term addition of microbial nutrients is not feasible or operable in car washes, and the cost is high.
Membrane filtration method: After pretreatment, it directly enters the filter membrane filtration treatment to achieve reuse. However, this method lacks a secondary treatment process, and the filter element and membrane need to be replaced after a certain period of time, and the operation and maintenance cost is high.
The above are some methods for car wash sewage treatment, and the specific choice of which method needs to be judged according to the actual situation.
