Potted-landscape-type aerating ecological wetland device and method for purifying black and smelly riverway by using same

Abstract

The invention relates to a potted-landscape-type aerating ecological wetland device and a method for purifying a black and smelly riverway by using the same. The potted-landscape-type aerating ecological wetland device comprises a box body, a pipeline, a aerator, a secondary sedimentation tank and a jet diffuser, wherein the pipeline is arranged at the bottom of the inner side of the box body, and penetrates through the whole box body; a filler is arranged inside the box body; the pipeline consists of a submerged pump, a main water pipe and a connecting pipe; the submerged pump is connected at one end of the main water pipe; the connecting pipe is arranged on the main water pipe; the connecting pipe is connected with one end of a branch pipe though a tee pipe; the other end of the branch pipe is connected with the aerator and the secondary sedimentation tank sequentially; the jet diffuser is connected to a water outlet pipe of the secondary sedimentation tank; a main gas pipe is arranged inside the box body; the top end of the main gas pipe is exposed in air; and the bottom end of the main gas pipe is connected with the main water pipe. Sewage can purified under the action of the potted-landscape-type aerating ecological wetland device; the potted-landscape-type aerating ecological wetland device can be flexibly installed at a riverway, is low in operating cost, is completely self-controlled, can restore aquatic ecological environment stably and sustainably, and is applicable to treatment of the black and smelly riverway.

Description

technical field [0001] The invention relates to the technical field of ecological purification treatment of river courses (natural rivers, urban inland rivers, black and odorous river courses). Background technique [0002] With the development of our country's economy and the improvement of people's living standards, people's requirements for environmental quality, especially water environment quality, are getting higher and higher, and the problem of pollution control of polluted surface water has also received more and more attention and attention. [0003] In the field of treatment of polluted surface water, there are two main types of treatment methods commonly used at present: biological method and ecological method. Biological methods use plants, animals and microorganisms to enrich, absorb and degrade pollutants to restore water bodies. The restoration process is natural and in situ, but it is easily affected by environmental factors. The ecological method mainly ad...
