Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a landscape water pollution control device. Background Art

[0002] In recent years, in the construction of urban green spaces, parks and residential areas, landscape lakes, landscape ponds and landscape pools have continued to emerge. Urban landscape water bodies are mostly closed slow-flowing water bodies with static or poor mobility, generally with the characteristics of small water area, easy pollution, small water environment capacity, and low water self-purification ability. With the accumulation of endogenous pollutants in landscape water bodies and the continuous input of exogenous pollutants, landscape water bodies gradually become eutrophic, organic matter and other impurities increase day by day, the dissolved oxygen concentration in the water body fluctuates dramatically, a large number of microorganisms in the water body begin to reproduce, and even a large number of planktonic plants and animals appear, which makes the water color and taste worse, and a large number of fish and other organisms die, affecting the overall beauty of the landscape and the living environment of residents. For this reason, it is necessary to treat landscape water bodies regularly to maintain the liveliness, aura and beauty of landscape water bodies.

[0003] Electrochemical oxidation technology is commonly used in the prior art to quickly remove organic pollutants from water. The basic principle of electrochemical oxidation technology is to reduce or remove pollutants from wastewater by direct electrochemical reaction or indirect electrochemical conversion on electrodes. It can be divided into direct electrolysis and indirect electrolysis. Direct electrolysis refers to the removal of pollutants from wastewater by direct oxidation or reduction on electrodes. Indirect electrolysis refers to the use of electrochemically generated redox substances (such as chlorates, hypochlorites, H2O2 and O3 with strong oxidizing properties, as well as solvated electrons, OH - 、O2 - Free radicals such as chlorinated paraffin and chlorinated paraffin are used as oxidants to convert pollutants into non-toxic and non-polluting substances. Electrocatalytic treatment technology has the characteristics of versatility, high flexibility, no pollution or less pollution, and easy control. At the same time, it has small equipment, small footprint, simple operation and management, and good treatment effect, and is increasingly valued by people. However, due to its shortcomings in actual application, such as high power consumption and unstable effect, and considering that there is no effective treatment method for landscape water on the market, the only way is to spend a lot of manpower to manually filter insoluble or slightly soluble substances or change water, which has caused great waste of existing resources.
