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] Livestock and poultry animals (such as pigs, cattle, sheep, chickens, etc.) in livestock and poultry farms are mostly raised in captivity by feeding feed in an open environment (such as a poultry house). Among them, there must be metabolic agents in the growth process of livestock and poultry animals, and people need to deal with 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, the excrement of livestock and poultry is removed from the poultry house and moved to the septic tank for processing; then the processed solids in the septic tank are sent to the composting site for subsequent processing. Thus, there are at least three sources of odor in livestock farms: excrement odors from livestock animals, odors from poultry houses and / or cesspools, and odors from composting sites. Among them, the...

Embodiment 2

[0048] A. Odor source control: 100 weaned piglets were randomly divided into 2 groups (control group and experimental group) and fed continuously for 30 days; the experimental group was fed with pig feed supplemented with 0.01% (w / w) feeding enzyme; the control group Feed pig feed without added feed enzymes. Compared with the control group, the feed conversion rate of the experimental group increased by 3.5%, the daily weight 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 combination device 2 may also include a temperature and humidity meter 26 for detecting the temperature and humidity in an open environment, and feeding back the detection results to the spray electric control box 25 . More preferably, the catalyst-ClO 2 Combined device 2 is provided with filter 27 between water...

Embodiment 3

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

[0057] B. Odor control in open environment:

[0058] The dust net is coated with CT catalyst (30g / m 2 ) and nano iron oxide (20g / m 2 ) composed of a combined catalyst, the temperature of the pig house is 22-28°C. Spray and disinfect the piggery every 36 hours, ClO 2 (Chlorine dioxide) concentration is 100ppm, every 60 minutes. After 12 days of testing, the stench of the experimental pig house has been greatly...

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 stench, in particular to a system and method for comprehensive control of stench in livestock and poultry farms. Background technique [0002] Odor in farms is a difficult and hot spot in the pollution control of farms. The malodorous gas in the farm will cause the immunity of livestock and poultry to decline, 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, every 10,000 pig farms emit an average of 15.9kg NH per hour to the atmosphere 3 , 1.45 kg H 2 S and 2.59kg feed dust. Taking ammonia as an example, studies have 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 will decrease b...
