Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1. Structure and Drafting Rules of Standardization Documents" drafted.

This document replaces GB/T 30887-2014 "Implementation Guidelines for Integrated Optimization of Water Systems in Iron and Steel Complexes", and GB/T 30887-2014 In contrast, apart from structural adjustments and editorial changes, the main technical changes are as follows:

a) Added "normative references" (see Chapter 2);

b) Modified the contents of some terms and definitions (see 3.1, 3.2, 3.3, 3.1, 3.3, 3.4 of the:2014 edition);

c) Increased the scope of investigation of petroleum refining, paper, alcohol, viscose and chemical fiber filament weaving enterprises (see 4.2.2, 4.2.3, 4.2.4, 4.2.5, 4.2.6);

d) Added the relevant content of "water system test" (see 4.4);

e) Changed the relevant technical content of "Drawing the current water network map" (see 4.5, 4.4 of the:2014 edition);

f) Added water quality constraints for petroleum refining, paper, alcohol, viscose and chemical fiber filament weaving enterprises, and classified them (see 5.2);

g) Added "The concentration of wastewater after regeneration should be determined according to the limit influent concentration with larger flow demand" in "Determining limit data". content (see 5.3.5);

h) Changed the relevant technical content of "integration optimization" (see 5.4.2.1, 5.4.1 of the:2014 edition);

i) Changed the relevant technical content of "Evaluation of water system integration optimization effect" (see Chapter 6, Chapter 6 of the:2014 edition);

j) Changed the relevant content in the appendix (see appendix A, appendix B, appendix C, appendix A, appendix C, appendix D of the:2014 edition).

1 Scope

This document provides guidance on the status quo investigation, integration optimization, and effectiveness evaluation of water system integration optimization in industrial enterprises.

This document is applicable to the optimization of water system integration in steel, petroleum refining, paper, alcohol, viscose and chemical fiber filament weaving enterprises.

The integration and optimization of water systems in other industries can be implemented by reference.
