On the pipeline between sump pump and the water distributor, be provided with trip switch; Described condensing works is by pipeline and the placed in-line structure of condensing chamber by water pump; One control valve is located between condensing chamber bottom and the pump chamber.

Characteristics of the present utility model are:

1. the utility model has utilized ozone-ultransonic synergy, difficult for biological degradation pollutent in oxidized waste water, the particularly thick-oil waste water, can make the macromolecular substance in the waste water be decomposed into the less material of molecular weight, become the compound of relatively easy degraded, thereby the BOD/COD value of waste water rises, compare with wastewater treatment equipment in the prior art, the biodegradability of waste water is improved, and helps follow-up aerobe and handles.

2. the utility model device has utilized ozone-ultransonic synergy to handle the emulsification oil extraction waste water, it is carried out breakdown of emulsion handle, and has improved the coherency of pollutent, helps follow-up coagulating treatment.

3. adopt the utility model with ultrasonic rationally integrated with ozone technology, its comprehensive cost is lower, compare with anaerobic biological treatment device of the prior art, the utility model processing efficiency obviously improves, and the hydraulic detention time of waste water shortened to about 10-20 minute by several days.
