METHOD FOR TREATMENT OF WASTE WATER IN SOLID DOMESTIC WASTE LANDFILLS Russian patent published in 2010 - IPC C02F9/00 

FIELD: technological processes.

SUBSTANCE: invention is intended for treatment of waste water in solid domestic waste landfills. Method for treatment of waste water consists in preliminary treatment of waste water 1, their disinfection with ultrasound 2, alternating supply in at least three accumulating reservoirs 3, 4, 5 and direction to biological treatment 15 with further sorption polishing treatment 16. Supply of waste water into accumulating reservoirs 3, 4, 5 is carried out cyclically according to scheme. According to scheme, each cycle is divided into subcycles, which include operations of filling, settling and drain, which are equal in time. In process of waste water settling, water samples are taken from reservoir and analysed, and on the basis of this analysis preparation is carried out for water drain from reservoir to biological treatment 16. Each subcycle lags behind the previous subcycle by one operation and leaves behind subsequent subcycle by one operation.

EFFECT: improved efficiency of waste water treatment with reduction of sorbent consumption.
