Optimization calculation method for allowable amount of pollutes poured into sea in different fields of coastal city

Abstract

The invention provides an optimization calculation method for the allowable amount of pollutes poured into the sea in different fields of a coastal city and belongs to the technical field of environment protection. According to the method, firstly, a target function is set. Based on the target function model, the water environmental capacity is allocated to each of all fields in the administrative region of a city on the premise that the coordinated development of economy, environment and society is ensured. Meanwhile, the maximal allowable discharge capacity of a pollute discharge unit is calculated. After that, a constraint condition is set. According to the constraint condition, on the premise that the principle of economic benefit, the principle of justice, the minimum standard of living and the coordinated development of economy, environment and society are ensured, the water environmental capacity is allocated to each of all fields in the administrative region. The constraint condition is conducted in three aspects, namely the economical aspect, the environmental protection aspect and the social aspect. According to the technical scheme of the invention, the model can be used for calculating the amount of main chemical pollutes poured into the sea in 13 circum-Bohai-sea cities by means of computer software. By adopting the above method, the allowable discharge amounts of COD and DIN in 13 circum-Bohai-sea cities can be quickly calculated, so that the guidance is provided for the pollute discharge amount in each circum-Bohai-sea city.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an optimal calculation method for the allowable discharge of pollutants from different industries in coastal cities. technical background [0002] The Bohai Sea is the only semi-enclosed inland sea in my country, with an area of ​​77,284km 2 , has unique resource advantages and land source advantages, and is an important support system for the Bohai Rim Economic Circle. However, with the continuous acceleration of industrialization, informatization, and urbanization of coastal cities, marine ecological environmental problems such as deteriorating water quality in coastal waters, frequent red tide disasters, unbalanced marine ecosystems, and decline in fishery resources are becoming more and more serious. Since the end of the 1970s, the quality of the marine environment in the Bohai Sea has generally deteriorated, especially in the mid-to-late 1990s. ...

Problems solved by technology

At the same time, the State Oceanic Administration began to implement the Blue Sea Action Plan in key bays and estuaries at the beginning of this century, and it is urgent to further improve the theory and calculation methods of total amount control; while the research on the total amount of pollutant discharge into the sea in my country is still in the research and exploration stage. Difficult to meet the actual needs of total pollutant discharge control
