Electromagnetic membrane suspension deodorization system for large-span sludge landfill, and operation method thereof

Abstract

The invention discloses an electromagnetic membrane suspension deodorization system for a large-span sludge landfill. The system comprises a beam column, a cross beam, a suspension guide rail, a motor, an electric pulley, an electromagnetic membrane suspension deodorization main machine, a cable pipe winding and unwinding device, a sling chain, an electromagnetic chuck, an electric guide pipe, a covering membrane, a deodorization panel and a secondary odor treatment device. The motor drives the electric pulley to enable the electromagnetic suspension deodorization main machine to move and position on the suspension guide rail, and the electromagnetic membrane suspension deodorization main machine sucks the deodorization panel pre-buried below the covering membrane into the air through the permanent magnetic chuck. Furthermore, the invention also comprises an operation method of the system. Odor generated by the sludge landfill is collected and purified through deodorization agent spraying and the secondary odor treatment device, large-area damage to the covering membrane is not needed, the system is convenient to move and deodorize above the large-span sludge landfill in an electromagnetic suspension mode, the adaptability is very high, and the possibility of odor poisoning of local construction personnel of the landfill can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of sludge landfill deodorization, and relates to an electromagnetic membrane suspension deodorization system, in particular to a system for realizing odor purification of large-span sludge landfills through electromagnetic membrane suspension technology and biochemical deodorization technology system and method of operation. Background technique [0002] The development of sludge treatment and disposal in my country is relatively late, and the sewage treatment plants built in the early stage generally have the tendency of "heavy water and light mud", pursuing the sewage treatment rate, while ignoring the final treatment and disposal of sludge, and most sewage treatment plants do not have complete supporting facilities Sludge treatment facilities. A lot of sludge is simply treated and then directly landfilled in the suburbs. Sludge landfills are one type of sewage storage ponds. Most of the sewage storage po...

AI Technical Summary

Problems solved by technology

Sludge landfills are one type of sewage storage ponds. Most of the sewage storage ponds have no anti-seepage measures, and the types of pollution are complex and diverse. Sediment, pond water, soil and groundwater are all polluted to varying degrees, and It is difficult to identify the pollution interface, and it is imminent to renovate the pollution reservoirs and ponds

However, domestic technology maturity in the treatment of sewage reservoirs and ponds is low, there are few large-scale old-fashioned sludge landfill reconstruction projects, and there is a lack of efficient pollution identification and comprehensive treatment programs and complete process systems

Landfill sludge has accumulated for a long time, anaerobic fermentation of microorganisms, microbial degradation of organic matter, etc. have caused a large amount of odorous gas inside the reservoir, and a large amount of odor will also be generated during the process of sludge extraction and transfer. How to remove the sludge Efficient and stable deodorization in the process of removal from landfill and dehydration will be the difficulty of exploration. There are still few related technologies for the treatment and disposal of old sludge in landfill.

[0003] On the other hand, the scale and size of many sludge landfills are so large that conventional deodorization devices and technologies are difficult to play a role in the treatment and disposal process

At present, there are very few efficient deodorization devices that can be placed in large-span sludge landfills in local areas. The inventions in related fields mainly focus on deodorization of conventional structures or sewage treatment facilities that are prone to odor. It is difficult to deodorize through simple Retrofit and use it for odor purification in sludge landfill
