| 摘要 |
The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The system comprises a commonly known septic tank and recirculation tank. Septic tank effluent is collected in the recirculation tank, from which it is continually dosed by means of a pump to the top of the treatment media of the recirculating filter through pressure compensating drip emitters. Continuous dosing of diluted residential septic tank effluent through drip irrigation emitters provides a slow consistent application of liquid rich in organic material and pathogens over the treatment media. The treated effluent is then recirculated if water is low or went to final disposal. |
