Circulating water purification system and method applicable to lakes

Abstract

The invention discloses a circulating water purification system and method applicable to lakes. The system comprises a water purification device and ecological floating plates, wherein a connecting device is arranged between every two ecological floating plates; the water purification device comprises a base and a water purification chamber; the water purification chamber is arranged on the base; and the water purification chamber is sequentially provided with a filtering and flocculating chamber, a negative oxyanion electrolysis release chamber, a membrane bioreaction chamber and an oxygen aeration chamber which are sequentially arranged from left to right. The method comprises the following steps: (a) preparing for construction; (b) constructing a temporary cofferdam; (c) pumping water in the construction area; (d) building the water purification device; (e) installing the ecological floating plates; (f) installing a water supply device; and (g) carrying out water conditioning. The system is simple, feasible, scientific and convenient, has the advantages of environment friendliness, no pollution, low cost and high efficiency, and can implement accurate control. The treated lake water is clean and pollution-free. The system well solves the problem of lake water pollution.

Description

technical field [0001] The invention relates to a circulating water purification system and method applied to lakes. Background technique [0002] With the improvement of living standards, artificial lakes and artificial lakeways are constantly emerging in urban green spaces, park construction and large landmark buildings. However, the enrichment of nutrients such as nitrogen and phosphorus in the water body causes abnormal proliferation of algae, resulting in algae blooms or lake indigo. The transparency of the water body decreases, the dissolved oxygen decreases, and the water quality deteriorates seriously. Diseases, etc., so it is necessary to control the water body. [0003] Commonly used physical methods in water treatment include aeration, sediment dredging and water scour. Aeration is to artificially aerate the water body through the aeration system, increase the dissolved oxygen in the water, improve the activity of aerobic microorganisms in the water body, and th...
