A kind of washing and deodorizing tower and its deodorizing method with microbial deodorant

Abstract

The invention relates to a washing deodorization tower. The washing deodorization tower comprises an air guide machine, a first-grade main tower, a second-grade main tower and a third-grade main tower, wherein a medicinal liquid box, a partition plate, a spray device and a dehydration device are successively, from bottom to top, arranged inside the main body of each grade of main towers; the partition plate is prepared from a polyhedral hollow sphere material; the medicinal liquid box is connected with a spray pump, a nutrient liquid pump and an acid liquid pump which are respectively connected with a spray device, a nutrient liquid box and an acid liquid box through a liquid delivery pipe; and the spray pump, the nutrient liquid pump and the acid liquid pump are all connected with a controller. The invention also relates to a deodorization method by using the washing deodorization tower cooperating with a microbial deodorant. The method comprises the following steps: deodorant preparation, equipment installation, spray liquid preparation, spraying, and medicinal liquid replacing and supplementing. The objective of the invention is to prepare a highly-efficient deodorant; meanwhile, aiming at the deodorant, the deodorization tower specially used for liquid-gas deodorization is designed; thus, cyclic spray utilization of the deodorant can be realized; good deodorizing effect can be achieved; and the usage amount of the deodorant can be maximally saved.

Description

technical field [0001] The invention relates to the application field of deodorants, in particular to a washing and deodorizing tower and a deodorizing method with microbial deodorants. Background technique [0002] The annual production of municipal solid waste in my country is about 140 million tons. Except for a small part of incineration, composting or recycling, more than 80% are transported to landfills for landfill treatment; in the future, sanitary landfill treatment will still be the The basic way of domestic waste disposal in my country. Sanitary landfill, as the most common waste disposal method at present, also has many pollution problems, especially the large amount of landfill leachate generated during the landfill process, if not properly disposed of, it will cause serious pollution to the surrounding water and soil. [0003] Landfill leachate is high-concentration organic wastewater leached from microbial decomposition, rainwater washing, and surface water an...

Sanitary landfill, as the most common waste disposal method at present, also has many pollution problems, especially the large amount of landfill leachate generated during the landfill process, if not properly disposed of, it will cause serious pollution to the surrounding water and soil

[0003] Landfill leachate is high-concentration organic wastewater leached from microbial decomposition, rainwater washing, and surface water and groundwater immersion during garbage stacking and landfilling. It contains high concentrations of ammonia and hydrogen sulfide, causing landfills and The surrounding area is smelly, seriously polluting the environment, and affecting the normal life of the surrounding residents; due to the limitation of manpower and material resources, most of the leachate from landfills is simply pretreated before being merged into urban sewage treatment pipelines or It directly flows into the urban sewage treatment system and is treated together, and the odor in the leachate is not treated, resulting in an extremely bad smell in the landfill. Therefore, the deodorization treatment of the landfill leachate is the key to ensuring the long-term and safe disposal of garbage; The main feature and difficulty of the filtrate is its high concentration of ammonia nitrogen and hydrogen sulfide. Therefore, a microbial deodorant with stable quality, outstanding effect and fast deodorization is developed, and combined with advanced deodorization equipment to solve the problem of existing garbage. The problem of odor pollution from leachate is imminent
