Car wash water contains a lot of surfactants and high SS. The processing flow is as follows:
Regulating tank-primary sedimentation tank (which can be integrated with regulating tank)-air flotation tank-biological contact oxidation tank-inclined plate (tube) sedimentation tank-intermediate tank-sand filtration-activated carbon-reclaimed water storage tank-reuse.
Since the country began to implement waste sorting, osawa Environmental Protection began to develop integrated kitchen waste leachate treatment equipment, which met the market demand. Osawa environmental protection kitchen waste leachate treatment equipment adopts physicochemical+two-stage AO biochemistry+"integrated reactor for biodegradation and separation" technology, with no concentrated solution and high treatment efficiency. The main advantages come down to the following points:
1) The effluent quality is good, stable and up to standard.
2) Equipment integration, simple construction and short construction period.
3) The floor space is small, and it can be used on the ground and underground.
4) Low operating cost.
And 5) the reverse osmosis membrane treatment process is not adopted, and membrane filtration concentrated solution is not generated, thus being environment-friendly.
6) It has a high degree of automation. With the intelligent level platform independently developed by osawa Environmental Protection, it can realize unattended operation and reduce the cost.
