4.1 Processing category
According to the processing category of meat processing enterprises, it is divided into: National Environmental Protection Bureau Approved on 1992-05-18 and implemented on 1992-07-01
a.
Livestock slaughtering and processing,
b. Meat product processing,
c. Poultry slaughtering and processing.
4.2 Standard Classification
The standard classification is divided according to the type of discharge into the water. GB13457-92
4.2.1 Wastewater discharged into Class I and II waters in GB3838 (except water body protection areas) and Class II sea areas in GB3097 shall implement the first-level standards. 4.2.2 Wastewater discharged into Class IV and V waters in GB3838 and Class III sea areas in GB3097 shall be subject to secondary standards. 4.2.3 Wastewater discharged into urban sewers with secondary sewage treatment plants shall comply with Level 3 standards. 4.2.4 Wastewater discharged into urban sewers without secondary sewage treatment plants must comply with the provisions of 4.2.1 and 4.2.2 respectively according to the functional requirements of the sewer effluent receiving waters. 4.2.5 In water body protection zones in Class I, IIⅡI waters and Class IIⅢI waters in GB3838 and Class I sea areas in GB3097, new sewage outlets are prohibited, and expansion and reconstruction projects are not allowed to increase the amount of sewage discharge. 4.3 Standard values ??
This standard stipulates indicators such as drainage volume and the maximum allowable discharge concentration of water pollutants for meat processing enterprises according to different years. The standard values ??are respectively specified as:
