1、ERM China 1 GB 8978-1996 ICS 13.030.20 Z 60 National Standard of the Peoples Republic of China Integrated Wastewater Discharge Standard GB 8978 - 1996 Issued on 4 October 1996 Effective on 1 January 1998 Issued by: National Environmental Protection Bureau State Technology Supervision Bureau ERM Chin

2、a 2 GB 8978-1996 Preface This standard revises the Integrated Wastewater Discharge Standard (GB8978-88). The main revision is the date line provision. The date line replaces the division in the original standard between existing units and new, expanded, or rebuilt units. Time periods are divided by

3、the date when this standard was implemented. Units built before 31 December 1997 are subject to the standards set for the first phase; and units built after 1 January 1998 are subject to the standards set for the second phase. The Integrated Wastewater Discharge Standard and industrial discharge sta

4、ndards should not operate concurrently. Wastewater discharged by the following industries is subject to the relevant national industrial standards: paper making industry, shipping, shipping industry, marine petroleum development industry, textile dyeing industry, meat product industry, synthetic amm

5、onia industry, iron and steel industry, utilization of aviation propellants, weapon industry, phosphate fertilizer industry, caustic soda and polyvinyl chloride (PVC) industry. All other units who discharge wastewater are subject to this standard. Excluding the twelve industries named above, the sev

6、enteen previously issued industrial water pollutant discharge standards listed below are all included in this revised standard. Comparing this standard and the original standard, the standard values of the first phase basically maintain the new, expanded, and altered levels. In order to control the

7、characteristic pollutants and other toxic and harmful pollutants in the seventeen standards included in this revised standard, ten controlling parameters are added into the standard; as to the second phase, forty controlling parameters are added, and the maximum allowable discharge concentrations of

8、 parameters such as COD, BOD5, and so on, are more stringent to some extent. This standard, from the day put into effect, will replace GB8978-88 and the following seventeen standards: GBJ48-83 Hospital Wastewater Discharge Standard (Trial) GB3545-83 Beet Sugar Industrial Water Pollutant Discharge St

Standards Quoted Articles of the following standards become articles of this standard when quoted in this standard. GB3097-82 Marine Water Quality Stand

25、ard GB3838-88 Surface Water Environmental Quality Standard GB8703-88 Radiation Protection Rules ERM China 4 GB 8978-1996 3. Definitions. 3.1 Wastewater: the general name for water discharged during production and living activities. 3.2 Discharge capacity: Refers to the discharge capacity of water us

26、ed directly in technological production during the production process. This does not include indirect cooling water, wastewater from boilers on factory grounds or power stations. 3.3 All pollution discharging work units: refers to all the work units under the scope of this regulation, which discharg

27、e pollutants. 3.4 Other pollution discharging work units: refers to the remaining pollutant discharging units other than those specified for control of specific parameters 4. Technical Contents 4.1 Standard Classifications 4.1.1 Wastewater discharged into a GB3838 Class 3 water area (excluding desig

28、nated protected areas and scenic areas), and wastewater discharged into a GB3097 Class 2 marine area, must meet Class 1 standards. 4.1.2 Wastewater discharged to a GB3838 Class 4 or 5 area, and wastewater discharged to a GB3097 Class 3 marine area, must meet Class 2 standards. 4.1.3 Wastewater disch

29、arged into city and town sewage systems which have a secondary wastewater treatment plant, must meet Class 3 standards. 4.1.4 Wastewater discharged into city and town sewage systems which do not have a secondary wastewater treatment plant, should be subject to provisions in 4.1.1 or 4.1.2 according

30、to the functional requirements of the water area which receives effluent from the sewage system. 4.1.5 The construction of new pollution outlets is forbidden in Class 1 and Class 2 water areas and Class 3 designated protection regions of GB3838; and in Class 1 marine areas of GB3097. Mass loading co

31、ntrols should be implemented on existing outlets in accordance with the functional requirements of the water body in order to ensure that the water quality of the receiving water body conforms with the relevant water quality standard. 4.2 Standard Values 4.2.1 Under this standard, pollutants are div

32、ided into two types according to their characteristics and method of control: 4.2.1.1 Sampling for Type 1 pollutants, regardless of industry or discharge method, and regardless of the Class of the receiving water body, should be undertaken at the outlet of the workshop or the workshop treatment faci

33、lity. The maximum allowable concentration must comply with the requirements of this standard. (The outlet at the tailings dam of a mining operation is not considered to be a workshop outlet.) 4.2.1.2 Sampling for Type 2 pollutants should be conducted at the outlet of the discharging work unit. The m

34、aximum allowable concentration must comply with the requirements of this standard. 4.2.2 This standard provides the maximum allowable discharge concentrations of Type 1 and 2 pollutants and the maximum allowable discharge capacities of some industries in different time periods. These are: 4.2.2.1 Th

35、e discharge of water pollutants from work units constructed before 31 December 1997 (including renovation and expansion), must concurrently implement the provisions in Table 1, Table 2, and Table 3. 4.2.2.2 The discharge of water pollutants from work units constructed after 1 January 1998 (including

36、 renovation and expansion) must concurrently implement the provisions in Table 1, Table 4, and Table 5. ERM China 5 GB 8978-1996 4.2.2.3 The construction date (including renovation and expansion) of the work unit is determined by the approval date of the Environmental Impact Assessment (EIA) report

37、or the Environmental Impact Form (EIF). 4.3 Other Provisions 4.3.1 If there are two or more types of wastewater at one outlet, and the relevant standards of the two types of water are not the same, the discharge standard of the combined wastewater is determined by Appendix A. 4.3.2 The maximum allow

38、able discharge load of industrial wastewater pollutants should be calculated according to Appendix B. 4.3.3 The maximum allowable total annual pollutant discharge amount should be calculated according to Appendix C. 4.3.4 For the discharge of wastewater containing radiation, the Radiation Protection

39、 Regulation (GB8703-88), as well as this standard, should be implemented. 5. Monitoring 5.1 Sampling site The sampling site should be chosen according to the provisions of 4.2.1.1 and 4.2.1.2 for the establishment of Type 1 and 2 pollutant discharge outlets. Discharge outlets should be properly mark

40、ed with signs, and wastewater flow measurement and wastewater ratio sampling equipment should be installed at the outlet. 5.2 Sampling frequency The frequency of monitoring industrial wastewater is determined by the production cycle. If the production cycle is less than eight hours, sampling frequen

41、cy is once every two hours. If the production cycle is more than eight hours, sampling frequency is once every four hours. The sampling of other wastewater should not be less than twice every 24 hours. The maximum allowable discharge concentration is calculated by the mean value per day. 5.3 Dischar

42、ge capacity The discharge capacity is controlled by the maximum allowable discharge capacity or the minimum water recycling rate, and is calculated by the mean value per month. 5.4 Statistics Consumption of raw materials and the production output of an enterprise are determined by the statutory mont

43、hly or annual report form. 5.5 Measuring methods The measuring methods of this standard are described in Table 6. 6. Supervision of the Application of the Standard 6.1 The administrative department of the peoples government of a country or higher in charge of environmental protection is responsible

44、for the supervision of the application of this standard. 6.2 If implementation of the national water pollutant discharge standard does not meet local water environmental requirements, the peoples governments of provincial, autonomous region or municipality directly under the Central Government can f

45、ormulate standards stricter than the national standard, which should be reported to the national administrative department in charge of environmental protection for the record.
