Intelligent film-covering biological deodorization system

Abstract

An object of the invention is to provide an intelligent film-covering biological deodorization system. The intelligent film-covering biological deodorization system is used for solving problems in malodorous gas treatment in the prior art. The intelligent film-covering biological deodorization system provided by the invention comprises an odor monitoring unit, an air exhaust control unit, a film covering biological filtration deodorizing unit and an intelligent control unit. The intelligent film-covering biological deodorization system is applicable to odor treatment of units such as organic waste disposal enterprises, livestock and poultry breeding farms, sewage treatment plants and chemical enterprises, and is also suitable for reforming the existing biological filtering devices. The intelligent film-covering biological deodorization system has the advantages of intelligence in deodorization, good deodorization effect, 24-hour operation, convenience in maintenance, energy saving, andthe like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and healthy breeding of livestock and poultry, and relates to an intelligent film-covered biological deodorization system. Background technique [0002] Stench refers to any odor that can stimulate people's olfactory organs, generally cause unpleasantness or disgust, and damage human health. Odor gases are mainly emitted from livestock and poultry breeding, urban life and industrial production, and are produced in various industries such as livestock and poultry breeding, waste treatment, sewage treatment, food and seafood processing, slaughtering, metallurgy, petroleum smelting, pharmaceuticals, and chemicals , with broadness, where NH 3 、H 2 S and CH 3 SH concentration is the main odor component. Odor gas pollution is one of the seven major environmental hazards in the world. It has become one of the major problems of environmental pollution, and it will also cause the globa...

Problems solved by technology

[0005] In actual use, it is found that the current biological deodorization method still has some shortcomings: (1) The deodorization effect of the open biological deodorization filter is easily affected by adverse weather. The pressure increases; in hot weather, the water in the deodorizing filter bed loses rapid dispersion and the odor adsorption capacity is poor, which can lead to a decline in the deodorizing effect; (2) Weeds are easy to grow, and a large number of grass seeds will be brought into the biological deodorization with the wind In the filter tank, weeds grow, and the weed root system growing on the surface of the biological deodorization filter will block the ventilation gap and reduce the deodorization efficiency. Therefore, it is necessary to spray herbicides frequently for weeding, but the herbicides will affect the filling. Microorganisms have a great influence and affect the deodorization effect to a certain extent; (3) Bacteria, fungal spores and bioaerosols in the biofilter are easy to float into the air with the purified air during the deodorization process, which is harmful to the health of employees and surrounding residents (4) Most odor generating sites lack real-time odor monitoring and treatment systems, and the exhaust is only turned on when the employees are working or the odor in the site is treated by regular exhaust, which cannot keep the odor concentration at all times. Within a reasonable range, it will also cause unnecessary power consumption
