This document replaces GB/T 18916.12-2012 "Water Intake Quota Part 12: Alumina Production", and GB/T 18916.12- Compared with 2012, except for structural adjustment and editorial changes, the main technical changes are as follows:

a) Changed the water supply range (see 4.1.2);

b) The measurement of various water quantities has been deleted (see 4.1.2 of the 2012 edition);

c) Changed the water quota quota (see Chapter 5, Chapter 5 of the 2012 edition).

Introduction

Water quota is a technical standard and an important basis for measuring the level of water conservation. basis for rationalizing and conducting water resource justification. The quota standard for water use is to verify the permitted water volume, carry out water-saving evaluation, carrier construction, and standard-to-standard management it is also an important means to implement the most stringent water resources management system.

GB/T 18916 will clarify the range of water intake, the supply range of water intake and the limits of water intake according to the characteristics of water use in different industries.

Metering, stipulates the calculation method of water intake quota, divides the quota index level, and makes requirements for quota management.

GB/T 18916 is proposed to consist of the following parts.

--- Part 1. thermal power generation;
