Industrial park terminal water treatment system assessment method

Abstract

The invention discloses an industrial park terminal water treatment system assessment method. Firstly an industrial park terminal water treatment system assessment indicator system including technical indicators, environmental impact indicators, economic indicators and operation management indicators is constructed, then the subjective weight of each assessment indicator is determined by adopting an analytic hierarchy process and the objective weight of each assessment indicator is determined by adopting an entropy weight method, and the comprehensive weight of each assessment indicator is calculated by utilizing the mode of combination of the subjective weight and the objective weight. Secondly the evaluation standard of each indicator of the industrial park terminal water treatment system evaluation space is determined based on the fuzzy comprehensive evaluation theory, the membership function of each assessment indicator is determined, the fuzzy judgment matrix of each assessment indicator is constructed, and the assessment result of the terminal water treatment scheme of each industrial park is further calculated. The advantages and the disadvantages of the industrial park terminal water treatment technology can be rapidly and accurately assessed so that feasible suggestions can be provided for the existing industrial park terminal water treatment technology, and reference can be provided for selection of the new industrial park terminal water treatment technology.

Description

technical field [0001] The invention relates to an evaluation method of a terminal water treatment system in an industrial park. Background technique [0002] As an important industrial organization model, industrial parks are measures taken by some developed countries after World War II to promote economic development and improve urban layout, which greatly promotes regional economic and social development. With the continuous strengthening of the construction of industrial parks and the continuous optimization of industrial layout adjustments, heavy polluting industrial enterprises and new industrial projects are gradually concentrated in the park, and the park has a large amount of sewage discharge, and is characterized by instability, complexity, and high hazards. , and most COD components are difficult to degrade, and the degree of harm to the water environment is far greater than that of pollutants discharged from domestic and agricultural sources, which poses a great ...

Problems solved by technology

With the continuous strengthening of the construction of industrial parks and the continuous optimization of industrial layout adjustments, heavy polluting industrial enterprises and new industrial projects are gradually concentrated in the park, and the park has a large amount of sewage discharge, and is characterized by instability, complexity, and high hazards. , and most COD components are difficult to degrade, and the degree of harm to the water environment is far greater than that of pollutants discharged from domestic and agricultural sources, which poses a great challenge to the terminal water treatment of industrial parks

[0003] At present, there are many evaluation methods for environmental pollution prevention and control technology, but there is no method for the evaluation of terminal sewage treatment technology in industrial parks

The existing domestic comprehensive industrial park sewage treatment plants mostly use the municipal sewage treatment system, and it is difficult to ensure that the water pollution prevention and control technology can adapt to the water quality characteristics of the terminal sewage in all industrial parks, resulting in unreasonable technology selection and difficult discharge of pollutants in a stable manner.

Therefore, a set of practical technology evaluation methods is needed to select the best available technology for terminal water treatment in industrial parks, so as to avoid the phenomenon that the sewage treatment effect in industrial parks is poor and cannot meet the standards stably.
