example 1

[0081] Project Example 1: The project is located at Qianpai River (Hongguan Town Section) in Xinyi City. The total length of River Channel 1 is designed to be 11.4km, the length of new embankment is 1.3km, the length of revetment is 15.0km, and the length of dredging of River Channel 1 is 7.5km. km, with a planned total investment of about 490,000 yuan.

[0082] The VOC content and total nitrogen content detected by purge-and-trap gas chromatography-mass spectrometry after 5 samplings of the treated river water body meet the detection requirements of "Surface Water Environmental Quality Standards" and "Urban Water Supply Quality Standards" , the main VOC pollutants detected were halogenated hydrocarbons (1,1-dichloroethylene, dichloromethane and bromochloromethane).

Abstract

The invention relates to the technical field of environment treatment, and particularly discloses a drainage basin treatment system and method based on water ecological environment function partition units. According to the drainage basin treatment system based on the water ecological environment function partition unit, the drainage basin treatment system comprises a protection slope, a restoration buffer wetland zone, a protection greening vegetation zone and a maintenance management and control zone from inside to outside in the width direction of a river channel drainage basin; a plurality of ditches are formed in the protection slope at intervals, grids are arranged in the ditches, and the ditches are communicated with water in the restoration buffer wetland zone; the protective greening vegetation belt comprises a high-rise green belt, a middle-rise green belt and a low-rise green belt; the restoration buffer wetland zone comprises a water body purification treatment area, a wetland ecological restoration area and a forest land ecological restoration area. The system has the effects of effectively treating and repairing the water ecological environment of the river drainage basin, improving and balancing water resources in the river drainage basin and enhancing the self-repairing speed of the water ecological environment in the river drainage basin.

Description

technical field [0001] The invention relates to the technical field of environmental governance, in particular to a river basin governance system and method based on water ecological environment functional zoning units. Background technique [0002] Water eco-environmental function zone refers to four areas, namely protection zone, reserve zone, buffer zone and development and utilization zone, which are divided according to the status of water resources, the status quo of water resource development and utilization, and the demand for water quantity and water quality of social and economic development. The rational allocation of water resources in the basin, the treatment of polluted water bodies and the rate of recycling and reuse. [0003] At present, although all provinces have divided water function zones, and on this basis, they have also carried out the management and control of river basins and comprehensive governance, but there is currently no specific and operable ...
