Water quality purification system for lake water body

Abstract

The invention discloses a water quality purification system for lake water body. The water quality purification system comprises a supporting column fixed on the bottom of a lake, wherein the supporting column is provided with a solar power generation device, a fountain device and a gas purification device; the solar power generation device provides electric energy for the fountain device and thegas purification device; the solar power generation device is positioned below a water level and is not in direct contact with the water body; the gas purification device is positioned in the water body; the supporting column is in slippage connection with a floating body installed on the fountain device; the fountain device comprises a water supply part arranged on the bottom of the lake, a branch pipe arranged on the floating body, a plurality of nozzles arranged on the branch pipe and an extension tube for communicating the water supply part with the branch pipe; solar energy power supply does not need additional energy consumption, energy is saved, environment is protected, and operation cost is low; gas and pollutant in water are in full contact, harmful substances, including organicmatters, nitrogen , phosphorus and the like, in water can be subjected to oxydative degradation through oxidization reduction reaction, and various bacteria in the water can be subjected to oxidization sterilization to achieve the purpose of water quality purification.

Description

technical field [0001] The invention relates to the technical field of environmental water treatment, more specifically, it relates to a lake water purification system. Background technique [0002] Lake eutrophication control and cyanobacteria bloom control are global issues. Under the interference of human activities, domestic sewage and various industrial wastewater continue to flow into lakes and reservoirs. At the same time, farmland fertilizers washed by rainwater also pour in, making The excess of nutrients such as nitrogen and phosphorus required by organisms in the lake water causes various water quality problems. According to incomplete statistics, about 90% of the lakes in the country are polluted to varying degrees. [0003] At present, the comprehensive improvement of domestic urban lakes is mainly based on municipal engineering methods such as sewage interception, pollution control, water diversion, aeration and re-oxygenation, sediment dredging and lake cases,...

AI Technical Summary

Problems solved by technology

[0004] However, in the actual treatment process of lakes, in order to realize the whole lake treatment, it must be carried out on a full scale, resulting in the purification capacity being idle and wasted under normal circumstances, large investment in treatment funds, and low efficiency
