City landscape water body alga-controlling and pollutant-removing device

Abstract

The invention relates to a city landscape water body alga-controlling and pollutant-removing device. In the device of the invention, the inside of a hexahedron frame is divided into two spaces along a direction against the current, namely a front V1 space and a back V2 space, a suspending biological packing ball with a diameter of 15mm is arranged in the V1 space, and pebbles with a diameter of 20mm loaded with tetrasilver tetroxide are arranged in the V2 space. The invention overcomes the separate defects of the drainage control, sediment release technology, the manual aeration technology, the bioremediation technology and the chemical alga-killing technology. The invention integrates the biological and electrochemical methods to degrade the organic pollutants in water body and control the growth of alga in water body so that through the combination action of the biological and electrochemical methods, alga in water body is hard to grow and propagate largely while the pollutants are removed; the biological film on the surface of the suspending biological packing ball grows to absorb the organic pollutants in water body; and the pebbles loaded with tetrasilver tetroxide adopts theelectric field function of the microcell to effectively kill alga microorganisms in water and inhibit the growth of alga.

Description

technical field [0001] The invention relates to a decontamination device, in particular to an urban landscape water algae control decontamination device. Background technique [0002] With the continuous development of urbanization in our country, people pay more and more attention to the quality of living environment. In many urban green spaces, parks, and residential areas, landscape water bodies such as artificial lakes continue to emerge. However, many urban landscape water bodies are polluted to varying degrees, and water body odor and eutrophication are relatively serious. This not only seriously affects the visual effect of the surrounding landscape, loses the function of landscape water bodies, but also reduces the quality of human settlements and affects The construction of urban ecology, therefore, it is urgent to control and restore the polluted landscape water body. [0003] Prior to the present invention, the existing technologies for controlling the growth of...

Problems solved by technology

The disadvantage of controlling drainage and sediment release technology is that the project investment is huge and cannot be popularized and applied; the artificial aeration technology uses mechanical equipment to artificially re-oxygenate to increase the concentration of dissolved oxygen in the water body and create conditions that are conducive to the water body ecosystem. However, this technology not only Large investment and high daily operation and management costs are required, and the operability is poor; bioremediation technology is a good method, which uses specific organisms to absorb, transform or degrade water pollutants to reduce or eliminate water pollution. Biological measures to restore the ecological function of the water body. This technology can effectively remove some organic matter in the water body, but this technology cannot control the algae in the water body; the chemical algae killing technology mainly kills algae and microorganisms by adding chemical agents, but it is not thorough and can only be used in emergency situations. use, but also cause secondary pollution
