A METHOD FOR THE PURIFICATION OF WASTE WATER OF CITY SOLID DOMESTIC WASTE PRODUCTS DUMPS

摘要

The invention concerns the field of ecology, in particular the technology of purifying industrial and domestic waste water. A method for the purification of waste water of city solid domestic waste products dumps includes liming and subsequent barometric-membrane treatment. As solvent to prepare lime milk used is concentrate being formed in the course of barometric-membrane treatment, and liming is performed at the medium pH values of not less than 11. Application of this method provides a degree of waste waters purification at the level of 91.5-93.5 %, increase of barometric-membrane separation efficiency to 4.5-4.8 mum/s and utilization of ecologically dangerous concentrate of barometric-membrane treatment.
