Method, device and system for treating landfill leachate

Abstract

The invention discloses a landfill leachate treatment method, device and system. The method comprises the technical process that based on the synergistic effect of a palladium catalyst supported on the surface of aluminum oxide and natural iron ores (including hematite, magnetite, siderite and the like), the device is fixed at the appropriate position of a reaction system, active free radicals (mainly hydroxyl radicals) are produced in site under the condition of hydrogen and oxygen leading, and contaminants including organic matter in wastewater such as leachate and dye wastewater are removed through interface mass transfer among gas, solid and liquid and relevant interface reaction. According to the organic wastewater treatment method, a good organic pollutant degrading effect is obtained through the synergistic effect of the fixedly supported palladium and the iron ores, and the continuous wastewater output and discharging process is achieved. In the organic wastewater treatment method, hydrogen and oxygen which do not participate in the reaction can be cyclically used, the fixedly supported catalyst can be repeatedly used, and the treatment cost is greatly reduced.

Description

technical field

[0001] The invention belongs to the field of waste water treatment, and more specifically relates to a treatment method, device and system for organic waste water-garbage leachate. Background technique

[0002] With the development of industry, pesticides and fertilizers, and various petroleum-derived materials industries, the pollution of water bodies by refractory organic pollutants such as phenols has become increasingly serious. Compared with general wastewater, the content of pollutants in this type of wastewater is relatively low, but it is difficult to be treated by most wastewater treatment systems, and the problem of its advanced treatment and discharge has not been effectively resolved. People who drink water containing trace amounts of organic pollutants for a long time are more likely to suffer from digestive tract cancer. At present, several commonly used wastewater treatment processes at home and abroad have unsatisfactory treatment effects on ...
