| titleOfInvention | Small sewage treatment hydrolysis and gas-stripping and precipitation technique method |
| abstract | The invention provides a small sewage treatment hydrolysis and gas-stripping and precipitation technique method which comprises the following steps of: underground sewage, integrated anaerobic hydrolysis acidifying adjustment lift pump pond, integrated sewage treatment pond for Z type gas-stripping reflux two-stage precipitation, and up-to-standard emission. The anaerobic hydrolysis acidifying adjustment lift pump pond is adopted to replace various conventional and non-conventional comprehensive pretreatment procedures, the integrated sewage treatment pond for Z type gas-stripping reflux two-stage precipitation is adopted to replace procedures of a fine-rack girt chamber, an A/O biochemical reaction basin, a nitration liquid internal-reflux pump basin, a secondary precipitation basin, a sludge internal-reflux pump basin, a sludge external-reflux pump basin, a coagulation-flocculation reaction basin and an inclined-tube precipitation basin, a contact sterilization basin and the like in an A/O activated sludge method. The method has the advantages of being small in occupied space, less in investment and medicine consumption and sludge discharge, low in energy consumption and cost, stable and controllable in water quality, simple and convenient to run and manage, especially suitable for high-efficiency and compact treatment of nitrogen and phosphorus removal of sewage of ten thousand tonnage/per day and below. |
