Water body purification rope, preparation method and application thereof

Abstract

The invention discloses a water purification rope and a preparation method and application thereof. The water purification rope comprises a rope core, a heat insulation layer, a heat conduction layer,a transition layer, a purification layer and a conductive piece. The rope core, the heat insulation layer, the heat conduction layer, the transition layer and the purification layer are sequentiallywrapped from inside to outside; the conductive piece comprises an electrode and a wire; the electrode is electrically connected with the wire; the electrode is embedded in the heat conduction layer; the wire extends from the electrode to the outside of the heat conduction layer; an eM bacterium culture agent, EM bacteria and graphite oxide are embedded in the purification layer. The preparation method comprises the following steps: preparing a purification solution; forming the heat insulation layer; forming a heat conduction layer; forming the transition layer; forming the purification layer;the application mode is that the water body purification rope is put into water to be purified; the purification rope utilizes a microbe immobilization technology to be applied to river sewage purification, so that the restriction of microbe space competition and easy loss of efficient strains are avoided, the restriction of environmental condition temperature is avoided, and the microbe immobilization technology also plays the advantage of efficiently removing pollution.

Description

technical field [0001] The invention relates to a water purification rope, a preparation method and application thereof, and belongs to the technical field of water purification. Background technique [0002] my country is short of water resources and is one of the world's water-poor countries. With the rapid development of China's economy and society, water sources are increasingly polluted by industrial wastewater, agricultural sewage, and domestic wastewater, which has a great impact on human life and health. The pollution of water sources has also made the problem of water shortage in our country more serious. Bioimmobilization technology is an emerging technology in the field of modern bioengineering. Immobilized microorganism technology refers to the method of chemically or physically locating microorganisms or enzymes in a limited space area and making them not suspended in water but still maintaining biological activity and reusable. Compared with the traditional ...

Problems solved by technology

However, there are few microorganisms brought out of the biological fluidized bed system, poor sewage purification ability, large liquid-solid contact area, and high BOD volume load. At the same time, the microbial suspension carrier in the reaction zone is easy to move in series, and will flow to the drainage together with the sewage The mouth and water inlet will be blocked, which will seriously affect the purification effect of sewage

[0003] In addition, due to the wide area of ​​the water basin and the complex geographical environment, the use of traditional integrated treatment equipment often takes up a large space, and the energy consumption and input cost are high. Therefore, how to achieve low energy consumption, low cost, and low space Occupancy rate of river sewage purification has become a technical difficulty

[0004] In addition, the reproduction and action temperature of environmental microorganisms is between 15 and 35 degrees Celsius, and the temperature in autumn and winter is often below 10 degrees Celsius. Therefore, microbial immobilization technology cannot function in autumn and winter, which has become a key factor restricting the application of microbial immobilization technology
