Systematic purification treatment method for garbage press filtrate in transfer station

Abstract

The application provides a system purification treatment method for the garbage press filtrate of the transfer station, comprising the following steps: (1) collecting the garbage press filtrate of the transfer station to the adjustment tank for homogenization treatment and sedimentation pretreatment; The to-be-processed amount and parameter conditions of the garbage press filtrate of the transfer station determine the first-level treatment of the garbage press filtrate of the transfer station: 1) the COD value and the ammonia nitrogen content of the garbage press filtrate of the transfer station and the garbage press filter fluid of the transfer station are greater than predetermined Threshold, parallel processing; II) When the amount of waste press filtrate to be treated in the transfer station and the COD value and ammonia nitrogen content of the transfer station waste press filtrate are less than or equal to the predetermined threshold, AOP advanced oxidation treatment or multi-level after enhanced coagulation treatment Anaerobic treatment; (3) Second-level treatment of the garbage press filtrate at the transfer station: biological denitrification treatment after step (2); (4) The treated sewage is discharged into the sedimentation tank for further treatment. The operation route of this method is one for use and one for standby, one for normal and one for emergency, which fully guarantees the normal and stable operation of the wastewater station.

Description

technical field [0001] The present application relates to the technical field of garbage treatment, in particular, to a system purification treatment method for garbage press filtrate in a transfer station. Background technique [0002] Urban waste landfills are generally built far away from urban areas, which puts great pressure on the removal and transportation of urban waste. The expert committee of the China Urban Environmental Sanitation Association recommends that when the transportation distance of garbage (to the garbage treatment plant) exceeds 20km, in order to reduce investment and transportation costs, a garbage transfer station should be built, and it is proposed that future garbage collection and transportation equipment should focus on promoting compression Garbage trucks and compressed garbage transfer stations. However, a large amount of press filtrate will be produced during the garbage compression process. This type of wastewater has the characteristics o...

Problems solved by technology

[0006] Due to the complexity of the composition of the filtrate and the large changes in water quality and quantity, it is difficult for the anaerobic or aerobic treatment process of the general biochemical method to be effective.
