METHOD OF PURIFICATION OF SEWAGE AND NATURAL WATERS FROM SULFATE IONS OF DIVALENT IRON |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: purification method involves clarification and normalisation of hydrogen rate, when source water with concentration of divalent iron sulfate ions under 100 mg/l is aerated at redundant pressure of 1-4 atmospheres for 1-5 minutes, at that the water is fed to aeration in the form of wet air pulp. After the aeration the water is sent to clarification. ^ EFFECT: elimination of reagent preparation, consumption and neutralisation costs; streamlining of technology and reduction of costs for obtaining precipitation with improved structure and smaller volume, and of water treatment before discharge to the fishery pools due to the absence of a reagent. ^ 1 tbl, 3 ex |
