Embodiment 1

[0036] This embodiment provides a biological treatment process for the odor produced by the resource utilization of chicken manure, which is used to treat the odor produced during the fermentation process of chicken manure, such as figure 1 As shown, the biological treatment process includes the following steps:

[0037] (1) Obtain the odorous gas produced in the chicken manure fermentation process.

[0038] (2) Pass the acquired odor gas into an ultraviolet photolysis purifier to complete a cycle process of photocatalytic cracking treatment.

[0039] In this embodiment, nano-perkin particles and nano-titanium dioxide dispersed on a molecular sieve carrier are used as catalysts in the ultraviolet photolysis catalyst, and ultraviolet rays are irradiated around the catalyst; the period of a single photocatalytic cracking cycle is 7-8 minutes. In the ultraviolet photolysis purifier, the mass fraction of nano-platinum particles in the catalyst is not less than 0.1%; the power of ...

Embodiment 2

[0050] This embodiment provides an odor treatment system for resource utilization of organic waste. The system adopts the biological treatment process as in Embodiment 1 to harmlessly treat the odor gas generated during the composting process of organic waste. Such as figure 2 As shown, the odor treatment system includes: a gas collection mechanism 1 , at least two ultraviolet photolysis purifiers 2 , a water washing tank 3 , an adsorption chamber 4 , a biological digestion chamber 5 , a sterilization device 6 , and a controller 100 .

[0051] Among them, the gas collection mechanism 1 is used to collect the odorous gas to be treated and discharge the gas to the rear section;

[0052] Such as image 3 As shown, two ultraviolet photolysis purifiers 2 are installed side by side at the rear section of the air collection port 11, and the gas collected by the gas collection mechanism 1 is discharged into the processing chamber of the ultraviolet photolysis purifier 2 for processi...

Abstract

The invention relates to the field of biological environmental protection, in particular to a biological treatment process for odor generated by chicken manure recycling. The biological treatment process comprises the following steps of: (1) acquiring odor gas generated in a chicken manure fermentation process; (2) introducing the obtained odor gas into an ultraviolet photolysis purifier to complete a cyclic process of photocatalytic cracking treatment; (3) introducing the gas subjected to photocatalytic cracking treatment into a water washing tank for water washing treatment; (4) introducing the gas subjected to water washing treatment into an adsorption bin for adsorption treatment; (5) introducing the gas subjected to adsorption treatment into a biological digestion tank containing a biological digestion solution for biological digestion treatment; and (6) performing high-temperature sterilization treatment on the waste gas discharged from the biological digestion bin, and then discharging the waste gas. The problem that an existing composting field deodorization technology is not thorough in deodorization effect, can hardly deal with a scene with large-flow odor gas and low in treatment efficiency is solved.

Description

technical field [0001] The invention relates to the field of biological environmental protection, in particular to a biological treatment process for odor generated by resource utilization of chicken manure. Background technique [0002] Chicken manure, pig manure and other poultry manure and straw are very high-quality compost materials that can be used to produce bio-organic fertilizers. However, because these materials contain a large amount of available organic matter, various harmful microorganisms are easy to breed during the natural composting process. These harmful microorganisms will produce various types of odorous gases when decomposing organic matter, which will cause environmental pollution and affect composting. The health of staff or residents around the site. [0003] The existing odor treatment methods are mainly combustion method, water washing method, adsorption method and physical dilution method, etc., and the above methods all have certain deodorizing ...
