Composite wet land artesian polluted river water purifying method

Abstract

A method for purifying pollutant river by stting up purifying regions on river beach or lake beach wet zones includes a primary purification and deep goingp urification. A pollute cut-off gate is set on the pollutant river, an outlet is set on the course in front of the gate, a deposit pool surrounded by grates stopping pollutes at the back of the outer, water from the deposit pool flows into the deep going purifying biological intensifying deposition pool cultivating suspending plants, water from it flows into distributing ditches then to the underflow wet zone pipe with a gag at the pipe outlet and an outlet on the pipe wall, limestones, cobbles are laid in layer on the pipe to let the water flow to a collecting ditch then to the surface wet zone with plants grown there and water coming out from the wet flow to the lower reach river courses.

Description

technical field [0001] The present invention relates to water pollution control and ecological restoration of inland water bodies, in particular to a composite wetland artesian purification system that utilizes beach wetlands and lake beach wetlands in estuary areas to construct purification systems, intercept and purify rivers entering lakes, and prevent lake pollution and eutrophication Ways to pollute river water. Background technique [0002] In the field of water pollution prevention and control, the prevention and control technologies for various point pollution sources are quite rich and mature, but there is a lack of economical, rapid and effective control technologies for non-point source pollution from vast rural areas, agriculture and runoff areas. Today, when point pollution sources have been basically controlled, non-point source pollution is the main pollution source that causes water quality pollution and eutrophication of rivers ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to address the problem of non-point source pollution control of rivers and lakes in my country, to explore the use of river beach wetlands and lake beach wetlands in estuary areas to build purification systems, to intercept and purify rivers entering lakes, to prevent lake pollution and eutrophication, and to address the water volume of polluted rivers, With the characteristics of large fluctuations in water quality and complex and diverse pollutants, referring to related content such as water conservancy projects, sewage treatment projects, and wetland ecological projects, and based on the comprehensive attributes of natural rivers, a compound wetland artesian method for purifying polluted river water is provided to achieve economical and effective , fast, durable and other goals
