Eutrophicated water body double-fluidised form block-proof artificial wet land system

Abstract

The invention discloses a eutrophic water body double-fluidization plugging-up proof artifical wetland system, which comprises the following parts: vertical flow processing unit, oblique flow processing unit and sludge collecting unit, wherein the vertical flow processing unit cascades oblique flow processing unit together, which is separated by baffle to form double-flow form; the gap is remained under the bottom of baffle for water; the sludge collecting unit lies on the end bottom of oblique flow processing unit; the eutrophic water body is entered into vertical flow processing unit through piecing hole pipe and oblique flow processing unit from bottom, which drains water from back top of oblique flow processing unit; the sludge is collected into sludge collecting unit, which is drained into water bulk with flow through valve directly; the accumulated sludge and aged biological film are removed effectively, which avoids block of filler effectively.

Description

technical field [0001] The invention relates to a sewage treatment process, in particular to an artificial wetland system which has two water flow states of vertical flow and oblique flow to treat eutrophic water bodies and has better anti-clogging ability, and belongs to environmental engineering technology field. Background technique [0002] Constructed wetland's unique ability to purify water pollutants has been paid more and more attention. Constructed wetland has broad development prospects in the prevention and control of water pollution in rivers and lakes in our country. [0003] The basic principle of constructed wetland treatment of water pollutants is as follows: After the constructed wetland system operates stably, a large number of microorganisms grow on the surface of the substrate and plant roots and form biofilms. When sewage flows through the wetland, a large amount of pollutants are intercepted by the substrate and plant roots. It is removed through the a...

Problems solved by technology

[0006] The purpose of the present invention is to purify the pollution of eutrophic rivers and lakes, and develop a dual-flow state and anti-clogging artificial wetland system for eutrophic water bodies, so as to solve the problems of low treatment effect and easy blockage of ordinary artificial wetlands with single flow state. At the same time, it also considers the ease of operation and operation management, as well as the landscape requirements of constructed wetlands
