Abstract

The invention discloses a landfill leachate reverse osmosis treatment device. The landfill leachate reverse osmosis treatment device comprises a coarse filtering device for performing coarse filteringon leachate raw water, an air floating device connected with the coarse filtering device; a sand filter connected with the air floating device, wherein the front end and the rear end of the sand filter are respectively provided with an automatic acid injecting device and a scale inhibitor input device; a fine filter connected with the sand filter, a first-stage reverse osmosis unit connected withthe fine filter through a high-pressure pump; a concentrated solution storage device connected with a concentrated solution output port of the first-stage reverse osmosis unit; and a second-stage reverse osmosis unit connected with a clear water output port of the first-stage reverse osmosis unit, wherein a clear water output port of the second-stage reverse osmosis unit is connected with a clearwater storage tank, and the clear water storage tank is connected to a clear water reservoir; and a control device is connected with a pH value adjusting device, the second-stage reverse osmosis unit, the first-stage reverse osmosis unit, the automatic acid injecting device and the scale inhibitor input device. The invention has the beneficial effects that the landfill leachate reverse osmosis treatment device is short in treatment flow, full-automatically controlled in treatment process, and small in occupied area.

Description

technical field [0001] The invention relates to the technical field of environmental protection wastewater treatment, in particular to a landfill leachate reverse osmosis treatment device. Background technique [0002] With the rapid development of my country's economy and the rapid growth of urban population, the problem of urban domestic waste is becoming more and more serious. How to dispose of urban waste has become a difficult problem for countries all over the world. Incineration power generation is currently the safest and most effective way of domestic waste disposal in the world. Through incineration, the volume of waste can be reduced by 85%, which not only reduces land occupation and environmental burden, but also can use burning waste to generate electricity, which has the advantages of reduction, high efficiency, and resource regeneration. [0003] However, in the process of garbage incineration, in addition to producing waste gas that pollutes the atmosphere,...
