Regional industrial hierarchical water requirement calculating method based on efficiency statistics

Abstract

The invention provides a regional industrial hierarchical water requirement calculating method based on efficiency statistics. The method includes following steps: obtaining industrial enterprise water consumption data and information; obtaining actual measurement water consumption data of industrial enterprises through measurement according to a water balance experiment; correcting the industrial enterprise water consumption data according to the actual measurement water consumption data of the industrial enterprises; calculating fractiles of different process water consumption series of the industrial enterprises according to the corrected industrial enterprise water consumption data; and calculating the industrial hierarchical water requirement according to the fractiles of different process water consumption series of the industrial enterprises. According to the regional industrial hierarchical water requirement calculating method based on efficiency statistics, the problems of inaccurate calculation and large deviation of the regional industrial hierarchical water requirement is solved, the industrial hierarchical water requirement can be accurately calculated, the industrial water consumption efficiency is improved, water resources are saved, and effective data bases can be provided for management guidance and allocation planning of industrial water consumption.

Description

technical field [0001] The invention relates to the field of water resource demand forecasting, in particular to a calculation method for regional industrial level water demand based on efficiency statistics. Background technique [0002] Water is the blood of industry. Water participates in a series of important links in the production of industrial and mining enterprises, and plays an important role in manufacturing, processing, cooling, purification, air conditioning and washing. With the rapid development of industry, water plays an increasingly important role in the industrial production process, and there are more and more ways to use it. Generally speaking, water mainly plays three roles in industrial production: (1) reaction medium, water As a raw material in the reaction process to participate in the reaction, such as in various separation units (absorption, extraction and gas stripping, etc.) (3) Auxiliary water, which does not participate in the direct industrial...

Problems solved by technology

[0004] At present, with the continuous advancement of industrialization, the contradiction between industrial water demand and water supply has become increasingly prominent. Due to the unbalanced regional development, industrial water use is complicated, there are many industries, and the water use situation varies greatly. Some existing methods for calculating the water demand of industrial enterprises can be integrated Estimating industrial water consumption is difficult to accurately calculate the water demand of industrial enterprises. The calculation process is complicated and the results have large deviations. It cannot objectively reflect the influencing factors of the entire industrial water use process. The guidance management and allocation planning of water demand provide a reliable basis, which will cause waste of water resources and increase the pressure and contradiction of production and domestic water. Therefore, the research on the calculation method of industrial water demand has become an important issue
