Problems solved by technology

[0003] At present, the leachate treatment of the transfer station generally uses membrane treatment technology. Although the effect of membrane treatment is acceptable, the investment cost of this process is relatively high, and it is easy for the transfer station leachate with high pollutant concentration. The formation of membrane fouling will bring inconvenience to operation and management, and the cleaning and replacement of the membrane will also increase the operating cost

Abstract

The invention relates to a disposal device of leachates of a garbage transfer station. The device solves the technical problems of low disposal efficiency and the like in the prior art. The disposal device for the leachates of the garbage transfer station comprises an insulating grid machine and an adjusting pool which are sequentially connected, wherein the insulating grid machine separates high-concentration suspended matter and pollutants with larger particle size in water. The device also comprises a biochemical system, a sedimentation pool for precipitating the leachates, a coagulation dosing pool for adding a coagulant into the leachates, a coagulation precipitation unit for carrying out coagulation precipitation on the leachates, and an active carbon pool for adsorbing and filteringthe leachates after coagulation precipitation, wherein the biochemical system is used for carrying out biochemical reaction disposal on the leachates by means of a biological contact oxidation method. The disposal device has the advantages that the cost is low, and the emission standard can be satisfied after disposal.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a treatment device for leachate of a garbage transfer station. Background technique [0002] The main sources of sewage in the garbage transfer station are domestic sewage, flushing wastewater and landfill leachate, and the treatment is mainly to treat the leachate produced in the process of waste extrusion and loading. Landfill leachate contains a large amount of pollutants. If it is not treated, it will seriously pollute the surrounding environment. It will have a bad impact on groundwater, surface water sources, soil, surrounding animals and plants, and even threaten the health of the general public. Therefore, landfill leachate must be treated effectively to minimize its impact on the environment. [0003] At present, the leachate treatment of the transfer station generally uses membrane treatment technology. Although the effect of membrane treat...
