Sewage discharging and purifying system for garbage temporary storage area of garbage transfer station and method thereof

Abstract

The invention discloses a sewage discharging and purifying system for a garbage temporary storage area of a garbage transfer station and a method thereof, and the system comprises a flushing device which is used for flushing leachate generated after the garbage temporary storage area is cleared and transported; a water collecting pit arranged under the ground of the garbage transfer station and is communicated with a drainage tank arranged on the ground; a sewage treatment subsystem comprises a collection and regulation tank, a floating oil filter, an iron-carbon electrolysis device, an intermediate tank, a security filter, an activated carbon filter and sewage disinfection equipment which are communicated in sequence; wherein the collecting and regulating tank is communicated with the water collecting pit through a water feeding pipeline and a lifting pump; the intermediate tank is provided with a coagulant dosing device; one end of the sewage disinfection equipment is communicated with the activated carbon filter, and the other end is connected with the blow-off pipeline through a sewer pipeline; and a high-pressure spray disinfection subsystem is arranged in the garbage temporary storage area and used for disinfecting the space and the ground of the garbage temporary storage area. The up-to-standard discharge and thorough disinfection of sewage treatment in the temporary garbage storage area are realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically, to a sewage discharge and purification system and method for a temporary garbage storage area of ​​a garbage transfer station. Background technique [0002] As a link between the source of waste generation and terminal treatment and disposal facilities, the garbage transfer station plays an important role in the management system of urban solid waste. The transfer station compresses and packs bulk garbage through receiving, sorting, and compressing devices, which not only realizes the sealing of garbage transportation, avoids the phenomenon of scattering and dripping during garbage transportation, but also improves the economy of long-distance transportation and reduces the need for vehicles. However, in the process of accepting, sorting and compressing bulk garbage at the garbage transfer station, a large amount of garbage leachate will be generated in the tempora...

AI Technical Summary

Problems solved by technology

The transfer station compresses and packs bulk garbage through receiving, sorting, and compressing devices, which not only realizes the sealing of garbage transportation, avoids the phenomenon of scattering and dripping during garbage transportation, but also improves the economy of long-distance transportation and reduces the cost of vehicles. However, in the process of receiving, sorting and compressing bulk garbage at the garbage transfer station, a large amount of garbage leachate will be generated in the temporary garbage storage area, especially for wet garbage, which will produce a large amount of high-concentration during the treatment and disposal process Wastewater, landfill leachate is a kind of high-concentration organic wastewater, which usually contains various organic pollutants, ammonia nitrogen, heavy metals and other inorganic compounds. If it is not effectively treated and disposed of, it will pose a huge threat to the surrounding environment and human health, and Leachate, etc. will also become more and more difficult to handle with the prolongation of storage time

[0003] Traditional landfill leachate treatment methods include biochemical and physical chemical methods, but biochemical or physical chemical methods can only reduce the organic components and solid particles in the leachate sewage, and it is difficult to meet the discharge standards of medical sewage, and the current temporary garbage storage area is still It is difficult to clean the ground leachate after garbage removal, and there is serious bacterial pollution in the garbage temporary storage area, and the working environment is harsh
