Water body ecological self-organizing repair system guided by photocatalysis in advance and using method thereof

Abstract

The invention discloses a water body ecological self-organizing repair system guided by photocatalysis in advance and a using method thereof. The water body ecological self-organizing repair system guided by photocatalysis in advance comprises at least two pile bodies, a photocatalysis net and a biological rope, the photocatalysis net is laid 10-20 cm below the water surface; the two ends of the photocatalysis net slidably sleeve the pile bodies through connecting ropes; a plurality of supporting rods crossing the net bodies are arranged at intervals on the photocatalysis net; rod sleeves areseparately arranged at two ends of the supporting rods; floating balls are arranged above the rod sleeves; biological ropes are arranged below the rod sleeves; balancing weights are arranged at the free ends of the biological ropes; and a composite of graphene, a visible light catalyst and a photosensitive material is loaded on the photocatalysis net. The using method comprises the steps of waterarea survey, net body design and assembly, net body laying, system operation and maintenance and water quality monitoring. The water body ecological self-organizing repair system guided by photocatalysis in advance enables aquatic organisms to be connected through food webs and adapt to the water environment, moving from chaos to order is achieved, and through feedback mechanism to iterate evolution and self-regulation, self-organization, self-maintenance and self-repair of aquatic ecosystems are achieved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water body ecological self-organization restoration system guided by photocatalysis first and a use method thereof. Background technique [0002] In the past 20 years, with the rapid development of my country's economy and the acceleration of urbanization, the scale and speed of the development and utilization of river and lake water resources have been greatly enhanced. River and lake reservoirs are important sources of industrial and agricultural water and domestic drinking water in my country. Due to the discharge of domestic wastewater and industrial sewage, rivers, lakes and reservoirs in our country are polluted to varying degrees. Water pollution seriously affects and threatens human survival and health, and restricts economic and social development. The average water quality compliance rate of 222 drinking water surface water sources in 113 key environmental prot...

Problems solved by technology

It is characterized by a simple structure of the treatment system, high treatment efficiency for many organic matter, and less affected by climatic conditions, but the treatment cycle is long, the floor area is large, it is difficult to degrade completely, and the operating cost is high

[0007] It can be seen that there are different degrees of problems in the current common water treatment methods, especially according to the water treatment standards of the EPA, the existing methods are difficult to completely remove the toxic organic substances in the water. Therefore, it is more economical to improve the technical level of water treatment and explore Effective water treatment methods have become the focus of current research in various countries

[0008] These technologies are mainly used to remove suspended solids, turbidity, and chroma in water, and the removal effect on dissolved organic matter is not good, while advanced treatment technologies have problems such as large investment and high operating costs.
