| titleOfInvention | The recovery method of high concentration nitrogen phosphate and sulfur waste water resource |
| abstract | The present invention relates to the recovery method of high concentration nitrogen phosphate and sulfur waste water resource, be have ammonia nitrogen, the high-concentration waste water of p and ses acid group at the same time in first add excessive magnesium oxide, phosphate radical and ammonium ion during which is made with water fully reacts, and generates the precipitation of ammoniomagnesium phosphate, takes out precipitate；The remaining water reuse calcium hydroxide containing sulfate radical reacts generation calcium sulfate.The present invention solves that high concentration useless Industrial Wastewater Treatment containing ammonia nitrogen, phosphorous and sulphuric acid etc. is not up to standard to enter that the element consumption such as nitrogen phosphorus sulfur in the Heavy environmental pollution and the wasting of resources and natural resourcess that environment causes is serious and the contradiction between scarcity that comes out gradually, by recycling, the consumption of above-mentioned element in natural resourcess will be greatly reduced, while also reducing the impact of environmental pollution. |
