Comprehensive treatment method for odour pollution of urban refuse landfill

Abstract

The invention discloses a comprehensive treatment method for odour pollution of an urban refuse landfill, which comprises the following steps of: collecting living area refuses by adopting a refuse compressing vehicle, performing compression pre-treatment on the raw refuses, conveying the pre-treated refuses to the refuse landfill, discharging the collected refuse sewage into a percolate treatment plant, and after treating the sewage by each covered and sealed treating unit, delivering the treated sewage into a biofilter for deodorization; pouring the compressed refuses into a mobile sealed air-inducing deodorization room, and removing the offensive odour in the room by mobile on-line monitoring deodorizing equipment; and first covering a layer of soil on the compacted refuse layer, then uniformly laying air ducts, and laying a layer of HDPF film. The method of the invention can obviously reduce the yield of odour substances of the raw refuses, improve the odour pollution of a landfill operating area, effectively restrain the odour pollution of the refuse percolate treatment plant, obviously reduce the annual reservoir capacity construction cost of the refuse landfill, decrease the using amount of landfill soil, save land resource, greatly expand the effective reservoir capacity of the refuse landfill and prolong the service life of the landfill.

Description

technical field [0001] The invention relates to a comprehensive treatment method for odor pollution in urban garbage landfills. Background technique [0002] With the rapid development of my country's social economy, the amount of urban domestic waste is increasing day by day. According to statistics, in 2008, the national urban domestic waste production amounted to 155 million tons, and the stockpiled amount of urban domestic waste reached 60 billion tons. More than 200 cities were surrounded by waste. one of the factors. At present, more than 80% of domestic waste in cities and towns in my country is disposed of by sanitary landfill. With the improvement of urban residents' requirements for the quality of living environment and the acceleration of urbanization, the problem of odor pollution generated during the landfill process has become increasingly prominent. Because the stench endangers the human respiratory, circulatory, endocrine and nervous systems, it can easily...

Problems solved by technology

[0003] The treatment of odor pollution in landfills generally adopts spraying chemical deodorants, increasing the amount of soil covered daily, and increasing the frequency of road flushing, etc., which not only has poor deodorization effect, high cost, and serious secondary pollution, but also consumes a lot of land resources and garbage. The effective storage capacity of the landfill, thereby shortening the service life of the landfill

At this stage, domestic research on odor pollution control of landfills is seriously backward, lacking mature, economical and effective technologies and means
