Scope: This standard specifies the relevant terms and definitions, evaluation index system and requirements for the evaluation of water-saving enterprises in the chlor-alkali industry. It is applicable to the water-saving evaluation of caustic soda and polyvinyl chloride production enterprises in the chlor-alkali industry.

Introduction

GB/T 37271—2018 Standard In-depth Interpretation

1. Background and Significance of Standard Formulation

As the problem of water shortage becomes increasingly serious, the country's requirements for water-saving enterprises are constantly increasing. This standard was proposed by the Ministry of Water Resources and the Ministry of Industry and Information Technology to promote the efficient use of water resources in the chlor-alkali industry and promote green and sustainable development. By standardizing enterprise management indicators and technical indicators, it provides the industry with a clear direction and development path for water conservation.

2. Comparative analysis of standard frameworks

Standard dimension	Technical indicator	Unit	Indicator value
Water intake	Water intake per ton of caustic soda (30%)	m³/t	≤5.5
Reuse	Reuse rate	%	≥96
Reuse	Indirect cooling water circulation rate	%	≥98
Water leakage	Comprehensive water leakage rate	%	≤1.5

3. Implementation suggestions and case analysis

Technical indicator optimization suggestions: Enterprises should give priority to water-saving equipment, such as high-efficiency circulating cooling systems and steam condensate recovery devices. It is recommended to conduct water balance tests regularly to identify water waste points and formulate water-saving transformation plans based on actual conditions.

4. Professional terminology explanation

Taking the indirect cooling water circulation rate as an example, this indicator measures the efficiency of cooling water reuse in an enterprise. Water use efficiency can be significantly improved by optimizing the circulation system design and strengthening equipment maintenance.
