Problems solved by technology

The concentration of some pollutants is very high, and it changes with the seasons of the year and different periods after landfill, so it is very difficult to deal with
Since the country promulgated new and strict discharge standards for landfill leachate in 2006, traditional treatment methods have been difficult to discharge up to the standard, so there are some shortcomings. The shortcoming is that when the discharge reaches the standard, the equipment investment is large , high operating costs

Abstract

The invention discloses a system for treating household garbage leachate, belongs to the environmental protection technical field, and relates to a technology for treating the household garbage lechate. The system for treating the household garbage leachate aims at reducing equipment investment and operating cost of the system for treating the household garbage leachate. The system for treating the household garbage leachate comprises a garbage leachate tank (1), a barrier (2), an aeration tank (4), a desilter (5), a sludge tank (6), a filtering tank (8), a reverse osmosis membrane treating tank (9), and a clean water tank (10). The system for treating the household garbage leachate is characterized in that a causticizing tank (3) is arranged between the barrier (2) and the aeration tank (4), the treating tanks are constructed by concrete, a former process tank is 0-0.6 meter higher than a later process tank, liquid flows naturally from the former process tank to the later process tank, machine-driven flow is replaced by natural flow, and therefore operating cost is decreased by around 50% compared with a traditional process. The system for treating the household garbage leachate is simple in structure.

Description

technical field [0001] The invention belongs to the technical field of environmental protection. It relates to a technology for treating leachate of domestic garbage. Background technique [0002] At present, with the development of the economy and the improvement of people's consumption level, the urban domestic waste is increasing year by year, and the sanitary landfill of its domestic waste is one of the common treatment methods at home and abroad. The infiltration of water in the landfill and ground precipitation makes the landfill plant produce a large amount of leachate. There are many kinds of pollutants in the leachate, including many toxic and harmful substances and refractory organic substances. The concentration of some pollutants is very high, and it changes with the season of the year and the time after landfill, so it is very difficult to deal with. Since the country promulgated new and strict discharge standards for landfill leachate in 2006, traditional tr...
