Refuse transfer station leachate treatment system and method thereof

Abstract

The invention discloses a garbage transfer station leachate treatment system and method thereof, at least two groups of filters of a primary filtering system are communicated in parallel, and a sand filter pipeline is connected with a chemical cleaning box, a pressure gauge and a water inlet pump; a first-stage membrane group and a second-stage membrane group of a precision filtration system are respectively communicated with a first-stage high-pressure pump and a second-stage high-pressure pump, the first-stage membrane group and the second-stage membrane group are connected with a concentrated water discharge pipeline, a water production pipeline and a raw water pipeline, the water production pipeline is communicated with a degassing tower, and water filtered and purified by the second-stage membrane group is degassed by the degassing tower and then stored in a water production tank; the two-stage membrane group combining parallel connection and series connection is matched with the primary filtering system and the precise filtering system, so that the landfill leachate can be treated in a two-stage series connection mode, the desalination rate reaches 98% or above, all produced water reaches the standard and is discharged, the problem of tail-end concentrated solution treatment is solved, the treatment efficiency is high, the operation cost is low, and full-amount treatment of the landfill leachate is realized.

Description

technical field [0001] The invention belongs to the field of garbage treatment, and in particular relates to a harmless treatment system and method for leachate of a garbage transfer station. Background technique [0002] With the improvement of social and economic level, the output of garbage, mainly domestic waste and kitchen waste, continues to increase, and the harmless treatment of garbage has always attracted attention. The sewage generated by the waste transfer operation belongs to the original landfill leachate, and it must meet the relevant standards after treatment before it is allowed to be discharged. The leachate composition of the garbage transfer station is complex, containing a large amount of organic matter, suspended solids, ammonia nitrogen, COD, heavy metal ions and germs, and the leachate concentration fluctuates greatly, so the requirements for leachate treatment technology are very high. At present, most garbage transfer stations use leachate to colle...

AI Technical Summary

Problems solved by technology

The former has the disadvantages of high treatment cost and low efficiency, while the latter will seriously pollute the environment. Therefore, it is very important for the garbage transfer station to propose a leachate treatment system that can operate stably and meet the discharge requirements.
