Embodiment 1

[0053] Table 1: Water quality of the membrane concentrate pool of a leachate treatment station of a domestic waste landfill in Guangshui City

[0054]

[0055] The source of the concentrated liquid in this example is the concentrated liquid retained by nanofiltration and reverse osmosis of the membrane advanced treatment unit of the main process. It can be seen from Table 1 that the water quality of the membrane concentrate pool has the characteristics of high conductivity, that is, high salt content, high concentration of non-biochemical and refractory organic pollutants, and the treatment is difficult.

[0056] The above-mentioned membrane concentrate is treated by the landfill leachate membrane concentrate solution provided by the present invention with a full amount of harmless zero discharge treatment system, and the treatment scale is 50m 3 / d, the system runs for 20 hours per day. The concentrated liquid retained by nanofiltration reverse osmosis is first stored in ...

Abstract

The invention relates to a membrane concentrated solution harmless treatment system and method, which solve the defects of the existing membrane concentrated solution treatment technology. According to the membrane concentrated solution full-amount harmless treatment process adopting advanced oxidation, membrane deamination and low-temperature evaporation, the advanced technology in the aspect ofhigh-concentration organic wastewater treatment is integrated, the concept of physical and chemical synergistic treatment is provided, and organic pollutants in the membrane concentrated solution aredecomposed into CO2 and H2O which are harmless to the environment in a chemical treatment mode; ammonia nitrogen pollutants in the membrane concentrated solution are separated into ammonia gas in a physical mode, and then the ammonia gas is absorbed by acid and alkali; and salt in the membrane concentrated solution is converted into solid miscellaneous salt in a physical mode, and full-amount harmless treatment of the membrane concentrated solution is achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a system and method for harmless treatment of membrane concentrated liquid. Background technique [0002] With the development of the economy and the rapid advancement of urbanization, the urban resident population has increased sharply, and the resulting domestic waste resource disposal is a major problem in contemporary urbanization governance. Nowadays, sanitary landfill and high-temperature incineration are generally used in the treatment of urban domestic waste. Both of them will produce landfill leachate during the treatment process. Its composition is complex, it is easy to produce stench, and contains many toxic and harmful substances. Disposal may pollute natural water bodies, thereby causing harm to human health. [0003] At present, most landfills and waste incineration plants in China have set up separate landfill leachate treatment stations, which usually adopt the m...
