Comprehensive treatment method for odour pollution of urban refuse landfill

A technology of odor pollution and comprehensive treatment, applied in the direction of deodorization, disinfection, solid waste removal, etc., can solve the problem of the effective storage capacity of waste landfills that consume large land resources, the lack of mature, economical and effective technologies and means, and the shortening of waste landfills. The service life of the field and other issues can be prevented to prevent the emission of odorous pollutants, save land resources, and improve the status of odorous pollution.

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 cons

Embodiment Construction

[0019] The comprehensive treatment method for malodorous pollution in urban refuse landfills of the present invention comprises the following steps:

[0020] 1) Use garbage compression trucks to collect garbage in the living area, compress and pre-treat the original garbage and transport it to the landfill, thereby reducing the moisture content of the garbage entering the landfill and reducing the amount of odorous substances in the original garbage; The garbage and sewage collected in the sealed collection box are discharged into each covered and sealed treatment unit of the landfill leachate treatment plant, and the malodorous gas generated during the treatment process of each treatment unit is collected and sent to the biological filtration device for deodorization; after biological filtration Deodorization treatment, the removal rate of the main odor pollutants H2S and NH3 produced in the leachate treatment process reaches more than 95%, and the reduction rate of odor inten...

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...
