Low-pollution closed landscape water body circulating purification system

Abstract

The invention relates to a low-pollution closed landscape water body circulating purification system. The system comprises a landscape water body, one end of the landscape water body is connected with a water diversion tube, the water diversion tube is provided with an elevator pump, the other end of the water diversion tube is connected to the front end of a high-load undercurrent constructed wetland system, the rear end of the high-load undercurrent constructed wetland system is connected with a water supply tube, the water supply tube is connected to the other end of the landscape water body, water in the landscape water body goes through the elevator pump and the water diversion tube, enters the high-load undercurrent constructed wetland system and is purified, and purified water goes through the water supply tube and flows back to the landscape water body; and a plurality of ecological floating islands and a photovoltaic fountain are arranged in the landscape water body. The low-pollution closed landscape water body circulating purification system has the advantages of simple process flow, low running cost, excellent comprehensive effectiveness, realization of reduction of pollutants in the water body and "clear water and flowing water" dual water quality keeping function on the premise of promoting flow of the water body by adopting a water power circulating technology as a main technology and comprehensively integrating offline purification and in-situ restoration technologies, simple technologic principle and good effect.

Description

technical field [0001] The invention relates to a low-pollution closed landscape water circulation purification system, which belongs to the technical field of water pollution control. Background technique [0002] No matter in terms of theory and technology, or in terms of engineering practice, water pollution control and sewage treatment have both connections and differences. In theory, both take the natural purification process of pollutants as a logical starting point, and achieve efficient removal of pollutants through strengthening measures under different conditions. But generally speaking, different from sewage treatment methods, water body treatment is to treat the water body and its surrounding environment as one, and pay attention to the protection of its surrounding environment while purifying the water body. According to the spatial relationship between engineering measures and water bodies, water body treatment is divided into in-situ restoration and ex-situ t...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that most of the landscape water bodies in the current water pollution treatment methods are artificially divided into closed areas due to the convenience of management, resulting in poor water fluidity, easy accumulation of water pollutants, and eutrophication and black odor phenomena. problem, a low-pollution closed landscape water circulation purification system is provided
