Screening method and device for treating large-area water-saving mold outbreaks in natural water bodies

Abstract

The invention belongs to the technical field of environmental protection. The invention provides a new method for removing water-saving mold when large-area water-saving mold breaks out in rivers, that is, a new green method of screen interception, physical collection and disposal. The invention also provides a device capable of effectively removing the water-saving mold when the water-saving mold breaks out in a large area in a river. The device is composed of a screen part and a part for extracting and scraping mildew. The sieve parts include a fixing device, a sieve device and a slide rail device; the extracting mold scraping parts include a slide rail transportation mold scraper and a mold collection bag. The specific steps are: the screen components are intercepted and placed across the river banks, and the water-saving mold in the water flow is intercepted on the screen; the mold scraper on the screen collects the water-saving mold intercepted on the screen into the mold collection bag, so as to achieve The purpose of removing water-saving mildew in rivers. Using the method and the device of the invention to remove the large-area erupting water-saving mold in rivers can ensure a 95% removal rate of the water-saving mold. The invention overcomes the disadvantages of high manpower cost and unclean manpower removal, and can quickly and effectively remove the water-saving mildew that breaks out in the water body. The invention has the advantages of convenient construction, high efficiency, low cost and simple operation.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection. The invention relates to a new method and device for removing water-saving mold when large-area water-saving mold breaks out in rivers, that is, a new green method for screen interception and physical collection and disposal. The parts are intercepted and placed across the river banks, and the water-saving mold in the water flow is intercepted on the screen, and the mold scraper on the screen collects the water-saving mold intercepted on the screen into the mold collection bag, so as to remove the water-saving mold in the river The method and device of the present invention can ensure a removal rate of 95% of water-saving mold by using the method and device of the present invention to remove large-area outbreaks of water-saving mold in rivers. Background technique [0002] Solidiasis is a low-level aquatic fungus, which belongs to the class Phycoides, Sojaea, and Sojaiaceae. It ...

Problems solved by technology

Leptomitus lacteus is a sewage fungus. When the river is polluted, it often explodes in a large area, presenting a "cotton-like" organism, which affects the water landscape and has potential harm to the water body. There have been Leptomitus lacteus in the United Kingdom and Germany Reports of large-scale outbreaks of water-saving fungus have also occurred in the ice-covered period of the Qiqihar section of the Nenjiang River in China, and in the wave section of the Mudanjiang River. Literature research at home and abroad shows that for the study of water-saving mold, relevant domestic and foreign Most of the research reports only stop at the preliminary research on its morphological characteristics, physiological and biochemical characteristics, etc., or simply analyze the causes of its occurrence in polluted rivers, and the control technology for the large-scale outbreak of S. Therefore, it is very meaningful to develop the key technologies for the removal and control of the large-scale outbreak of the mildew

In order to solve the pollution caused by water-saving mold to water bodies, whenever water-saving mold breaks out, huge human resources must be mobilized to salvage, which has the problems of time-consuming, laborious and high cost, and the problem of low salvage efficiency, and will be salvaged. The accumulation of water-saving mold on the river bank will cause secondary pollution to the environment. If chemical agents are thrown into the river to separate the water-saving mold, it will also cause secondary pollution
