GB18596—2001
This standard is formulated to implement the Environmental Protection Law, the Water Pollution Prevention and Control Law, and the Air Pollution Prevention and Control Law, to control the pollution of wastewater, waste residue and odor generated by livestock and poultry breeding to the environment, to promote the technological progress of livestock and poultry production technology, and to maintain ecological balance. This standard is only applicable to intensive and large-scale livestock and poultry breeding farms and breeding areas, and is not applicable to free-range livestock and poultry breeding. According to the scale of breeding, it will be gradually controlled in stages, and the combination of breeding and ecological breeding will be encouraged, so as to gradually realize the rational layout of the breeding industry in the country. According to the characteristics of pollutant emissions from livestock and poultry breeding, the pollutant control items specified in this standard include chemical indicators, hygienic indicators and sensory indicators. In order to promote the reduction, harmlessness and resource utilization of pollutants from livestock and poultry breeding, this standard stipulates the emission standards of wastewater and odor and the environmental harm of waste residue.
This standard is formulated for the first time.
This standard is proposed by the Science and Technology Standard Department of the State Environmental Protection Administration. This standard was drafted by the Environmental Protection Research and Monitoring Institute of the Ministry of Agriculture, Tianjin Animal Husbandry Bureau, Shanghai Animal Husbandry Office, and the Institute of Environmental Sciences of Shanghai Academy of Agricultural Sciences.
This standard was approved by the State Environmental Protection Administration on November 26, 2001. This standard is interpreted by the State Environmental Protection Administration. 1 Subject content and scope of application
1. 1 Subject content
Pollutant emission standard for livestock and poultry breeding industry
GB18596:2001
This standard specifies the maximum allowable average emission concentration and maximum allowable discharge volume of water pollutants and malodorous gases, and the harmless environmental standards for livestock and poultry slag according to the different scales of intensive livestock and poultry breeding industry. 1.2 Scope of application
This standard applies to the emission management of pollutants from intensive livestock and poultry farms and breeding areas throughout the country, as well as the environmental impact assessment, environmental protection facility design, completion acceptance and emission management of these construction projects after commissioning. 1.2.1 The scale classification of livestock and poultry farms and breeding areas to which this standard applies shall be implemented in accordance with Tables 1 and 2. 1 Applicable scale of intensive commercial poultry farms (in terms of number of livestock and poultry in stock) Category

1.2.2 For farms and breeding areas with different types of livestock and poultry, the scale can be converted from the breeding of chickens and cattle to the breeding of pigs. The conversion ratio is: 30 eggs One chicken is converted into one pig, 60 broiler chickens are converted into one pig, one dairy cow is converted into 10 pigs, and one beef cattle is converted into five pigs.
1.2.3 All intensive livestock and poultry farms and breeding areas within the first-level scale range, as well as intensive livestock and poultry farms and breeding areas within the first-level scale range and located in national key environmental protection cities, key river basins and seriously polluted river network areas, shall implement the standards from the date of implementation.
1.2.4 For intensive breeding farms and breeding areas within other regional scale ranges, the specific time for implementation of the standards may be determined by the environmental protection administrative department of the people's government at or above the county level, but shall not be later than July 1, 2004. 1.2.5 For intensive sheep farms and sheep breeding areas, the sheep breeding volume shall be converted into pig breeding volume, and the conversion ratio is: 3 sheep are converted into 1 pig. The scale level of the sheep farm or sheep breeding area shall be determined based on the converted breeding volume, and shall be implemented in accordance with the provisions of this standard. 2 CB 185962001 2.2 Intensive livestock and poultry breeding area refers to an area with a certain distance from residential areas and where multiple livestock and poultry breeding individuals are concentrated after administrative division. 2.3 Slag refers to solid wastes such as livestock and poultry excrement, livestock feed including bedding, waste feed and scattered feathers discharged from the breeding farm. 2.4 Harmful pollutants refer to all gaseous substances that stimulate the sense organs, cause discomfort to people and damage the living environment. 2.5 Odor concentration
refers to the dilution multiple required when malodorous gases (including odor) are diluted with odorless air until they are completely odorless. 2.6 Maximum allowable discharge volume
refers to the maximum allowable discharge volume of water directly used for production in the livestock and poultry breeding process. 3 Technical content
This standard is divided into the following three parts according to the discharge of water pollutants, wastewater and malodorous gases. 3.1 Discharge standard of pollutants in livestock and poultry breeding water 3.1.1 Livestock and poultry breeding water shall not be discharged into sensitive waters and waters with special functions. The discharge destination shall comply with relevant national and local regulations.
3.1.2 The discharge of water pollutants from poultry breeding within the scope of the standard shall comply with the provisions of Table 3, Table 4 and Table 5 respectively. 3. The maximum allowable discharge volume of water flushing technology in intensive poultry breeding industry is calculated as follows: [m*/(hundred heads·d)] [m\ (annual heads·d)] [H ... The maximum permissible discharge volume in autumn is calculated based on the average of winter and summer.

3.2 Environmental standards for harmless treatment of livestock slag from breeding industry 3.2.1 Livestock breeding industry must have fixed storage facilities and places for slag, and the storage places must have measures to prevent leakage and overflow of manure liquid. 3.2:2 The poultry manure used for direct return to the field must be treated harmlessly. 3.2.3 It is prohibited to dump the residue directly into the surface water or other environments. When returning livestock and poultry manure to the field, it must not exceed the local maximum farmland load to avoid non-point source pollution and groundwater pollution. 3.2.4 The waste residue after harmless treatment shall comply with the provisions of Table 6. 2

3.3 Emission standards for harmful pollutants from livestock breeding industry 3.3.1 The emission efficiency of harmful pollutants from intensive livestock and poultry farming shall comply with the provisions of Table 7, which means that the mortality rate is ≥95% and ≤10% of the individual/kg. Table 7 Emission standard of harmful pollutants from intensive livestock and poultry farming Control items Daily Gas concentration (special category) Standard value GB18596-2001 3.4 Poultry farming should actively use the pollutants discharged through the return of wastewater and feces to the fields or other measures to achieve the source of pollutants. 4 Monitoring The sampling points and sampling frequency of pollutant items monitored daily shall comply with the requirements of the national environmental monitoring technical specifications. The monitoring methods of pollutant items shall be implemented in accordance with Table 8.
