Technical Guidelines for Coal Chemical Wastewater Treatment and Reuse

1 Scope

This document stipulates the basic requirements, wastewater categories and technical requirements for coal chemical wastewater treatment and reuse. This document is applicable to the treatment and reuse of wastewater produced by using coal as raw material to produce fuels and chemical products through coal gasification or coal liquefaction processes. technical guidance.

2 Normative reference documents

The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document. GB/T 18920 Urban sewage recycling and urban miscellaneous water quality GB/T 21534 Water conservation terminology GB/T 50050 Design specifications for industrial circulating cooling water treatment GB/T 50483 Environmental protection engineering design standards for chemical construction projects GB 50684 Design specifications for chemical industry wastewater treatment and reuse GB/T 50977 Water-saving design specifications for chemical engineering SH/T 3099 Petrochemical water supply and drainage water quality standards

3 Terms and definitions

The terms and definitions defined in GB/T 21534 and the following apply to this document.

4 basic requirements

4.1 Coal chemical industry wastewater should follow the principles of classified collection, graded and qualitative treatment and qualitative reuse. After wastewater treatment, priority should be given to self-use. The overall process See Appendix A for the route. Among them, wastewater classification and quality treatment should include device pretreatment, wastewater treatment system, recycled water treatment system and concentrated brine processing system. 4.2 For coal chemical industry wastewater, technically and economically reasonable wastewater should be selected based on water quality, water quantity, reuse requirements, discharge standards and corporate water-saving goals. Treatment and recycling technology should comply with the provisions of GB/T 50483, GB 50684 and GB/T 50977.If necessary, the treatment can be determined through testing. processing technology. 4.3 When the quality of wastewater does not meet the water inlet index requirements of the wastewater treatment system, the device can be pre-treated to meet the requirements before it can be discharged into the wastewater treatment system. The processing technology should comply with the requirements of GB 50684. 4.4 The wastewater classification and quality treatment process should be carried out after obtaining the water quantity and quality of source water and wastewater, as well as the water quality requirements of recycled water. The water (salt) balance is determined after calculation. The full analysis report of water source quality is shown in Appendix B.

5 wastewater categories

5.1 Coal chemical industry wastewater includes process production wastewater, public engineering wastewater, auxiliary engineering wastewater, as well as floor washing water, initial contaminated rainwater, and separation ......
