Problems solved by technology

Pure organic filler mixture, although the organic filler itself is rich in microorganisms, and organic matter can provide rich nutrients for the growth of microorganisms, but with the accumulation of microorganisms, the porosity of the filler decreases, resulting in compaction of the filler, which is easy to cause system failure. jam

Embodiment

[0041] The odor generated by the sewage treatment plant enters the odor treatment system through the fan, and the intake air volume is 300m h -1 , water distribution pipe tap water drip filter capacity 9×10 -3 m -3 h -1 . By monitoring the deodorization effect of the system for 30 days, the main odor pollutant H in the odor 2 The concentration of S is (0.148~0.684) mg·m -3 Between, after being processed by the multimedia system, H 2 The concentration of S is (0.013~0.064)mg·m -3 Between, the removal rate is over 84.5%, and the average removal rate is as high as 91.8%; NH 3 The intake air concentration is (0.107~0.652)mg·m -3 Between, the average is 0.310mg·m -3 , after system purification, in (0~0.081)mg·m -3 between, with an average of 0.040mg·m -3 . Its removal rate is above 75.2%, and the average removal rate is as high as 87.8%. At the same time, the odor concentration is used as the monitoring index, and the intake odor concentration is (977-4121) OU m -3 Betw...

Abstract

The invention discloses a smelly-gas treatment system based on combination of multiple filter material media in the field of biological material smelly-gas treatment and a method. The system is mainly composed of soil mixed layers, inorganic filler layers, a large-particle zeolite layer, a draught fan, a water distribution pipe, a gas distribution pipe, a grille board and a water discharging valve; and the grille board is located between one inorganic filler layer and the large-particle zeolite layer, the water distribution pipe is located at the top of the system, and the water discharging valve is located at the bottom of the system. Gases sequentially enter the large-particle zeolite layer, the inorganic filler layer and the soil mixed layer through conveying by the draught fan, are adsorbed by volcanic rock and then are subjected to metabolic conversion by microorganisms, so that the smelly gases are treated effectively. Compared with a smelly-gas treatment system which simply utilizes an inorganic filler or an organic filler, the system provided by the invention has the advantages that the system can effectively adsorb and treat the smelly gases for a long time, the microorganisms in a filler can be recycled, and the system is not easy to block.

Description

technical field [0001] The invention belongs to the field of biological material odor treatment, and specifically introduces an odor treatment system and method combining multiple filter materials and media. Background technique [0002] At present, in the process of organic waste treatment such as urban sewage treatment and landfill, a large amount of odor containing various odor pollutants will be produced. These pollutants mainly include inorganic substances such as hydrogen sulfide and ammonia, and organic substances such as low-molecular fatty acids, amines, and halogenated hydrocarbons. Many VOCs substances have foul smell, and quite a few VOCs are carcinogenic and genetically toxic. Long-term exposure to VOCs gas will cause damage to human vision, hearing, and memory; primary alcohols, ethers, aldehydes, Solvents such as ketones damage the nervous system of the human body; benzene and toluene damage the kidneys, liver, blood system and nervous system; Has been desig...
