| titleOfInvention | A kind of processing method of Electronics Factory's high phosphorus high-nitrogen waste water |
| abstract | The invention belongs to field of waste water treatment, and in particular to a kind of processing method of Electronics Factory's high phosphorus high-nitrogen waste water includes the following steps: step 1, and ferrous sulfate, lanthanide series compound, active carbon and water are mixed, and configuration forms medicament；Step 2, medicament is added into waste water, metal powder is then added, aqueous slkali is added and adjusts pH to 10-11, is stirred to react 60min or more, obtains reaction solution；Step 3, Polyferric Sulfate and polyacrylamide are added in reaction solution, supernatant is extracted after coagulating sedimentation, obtains supernatant and waste residue；Step 4, supernatant is added to the processing of comprehensive wastewater biochemical system, obtains relief liquor；Step 5, filter residue is added to filters pressing in filter press and obtains solid waste, as fixed-end forces.The present invention utilizes the reproducibility of elemental metals and ferrous ion, under alkaline condition, phosphorus drop nitrogen is dropped in the way of absorption and coagulation precipitating, is aided with biochemical system, guarantees that draining reaches national sewage comprehensive emission standard. |
