Problems solved by technology

[0004] The main disadvantage of the existing technology is that most deodorization is only for a certain link, and there is no comprehensive deodorization control for the entire farm; the deodorization method is single and the effect is limited

Embodiment 1

[0033] Most of the livestock and poultry animals (such as pigs, cattle, sheep, chickens, etc.) in livestock farms are raised in captivity by feeding them in an open environment (such as poultry houses). Among them, there must be new agents in the growth process of livestock and poultry animals, and people need to dispose of livestock and poultry excrement in time to ensure the environmental sanitation of the farm and obtain certain economic benefits. The treatment of livestock and poultry excrement generally goes through the following process: first remove the livestock and poultry excrement from the poultry house and move it to the manure tank for processing; and then send the treated solids in the manure tank to the composting site for subsequent processing. In this way, there are at least three sources of odor in livestock and poultry farms: the odor of livestock and poultry animal excrement, the odor of poultry houses and / or manure tanks, and the odor of composting sites. A...

Embodiment 2

[0048] A. Odor source control: 100 weaned young pigs were randomly divided into 2 groups (control group, experimental group) and fed continuously for 30 days; the experimental group was fed pig feed supplemented with 0.01% (w / w) feed enzyme; control group Feed pig feed without adding feed enzymes. Compared with the control group, the experimental group's feed conversion rate increased by 3.5%, daily gain was 5.1%, and the incidence rate was reduced by 20%. Through sensory evaluation, the main odor components were significantly improved.

[0049] B. Odor control in open environment:

[0050] Combine Figure 4 Shown, photocatalyst-ClO 2 The combined device 2 may also include a thermometer and hygrometer 26 for detecting the temperature and humidity in the open environment and feeding back the detection result to the spray electric control box 25. More preferably, the catalyst -ClO 2 The combined device 2 is provided with a filter 27 between the water pump 23 and the water tank 24 fo...

Embodiment 3

[0056] A. Odor source control: 100 weaned young pigs were randomly divided into 2 groups (control group, experimental group), and fed continuously for 30 days; the experimental group was fed pig feed supplemented with 0.04% (w / w) feed enzyme; control group Feed pig feed without adding feed enzymes. Compared with the control group, the experimental group's feed conversion rate increased by 5.7%, daily weight gain was 11.09%, and the disease rate decreased by 29%. Through sensory evaluation, the main odor components were significantly improved.

[0057] B. Odor control in open environment:

[0058] The dust screen is coated with CT catalyst (30g / m 2 ) And nano iron oxide (20g / m 2 ) The composition of the combined catalyst, the pig house temperature is 22-28 ℃. Spray disinfection of the pig house every 36 hours, ClO 2 (Chlorine dioxide) The concentration is 100ppm, 60 minutes each time. After 12 days of testing, the stench of the experimental pig house has been greatly improved. Co...

Abstract

The invention discloses a comprehensive foul smell control system and method for a livestock and poultry farm. The comprehensive foul smell control system for the livestock and poultry farm comprises an open environment foul smell control system and a concentrated environment foul smell control system, wherein the open environment foul smell control system is a photocatalyst-ClO2 combination device around a livestock and poultry house and / or a cesspool; the concentrated environment foul smell control system is a bio-trickling tower-photocatalyst all-in-one machine arranged in a compost place. The comprehensive foul smell control method for the livestock and poultry farm comprises the steps of A, foul smell source control; B, open environment foul smell control; and C, concentrated environment foul smell control. The system can effectively reduce foul smell discharged from the livestock and poultry farm and is beneficial to ecological breeding and the health of workers.

Description

Technical field [0001] The invention belongs to the field of comprehensive management of malodor, and particularly relates to a system and method for comprehensive control of malodor in livestock and poultry farms. Background technique [0002] The stench of farms is a difficulty and a hot spot in pollution control of farms. The foul gas from farms can cause the immunity of livestock and poultry to decrease, affect the growth of livestock and poultry, and interfere with the sense of smell of nearby residents, often causing residents to complain and protest, directly restricting the development of my country's ecological animal husbandry. According to statistics, for every 10,000 pig farms, an average of 15.9kg NH is emitted into the atmosphere every hour 3 , 1.45kgH 2 S and 2.59kg feed dust. Taking ammonia as an example, the study found that when the volume fraction of ammonia in the air in the living environment of young pigs reaches 0.005%, the weight gain rate of young pigs w...
