A water purification rope, its preparation method and application

Abstract

The invention discloses a water body purification rope, its preparation method and its application. The water body purification rope includes a rope core, a heat insulation layer, a heat conduction layer, a transition layer, a purification layer and a conductive part; the rope core, a heat insulation layer, a heat conduction layer, The transition layer and the purification layer are wrapped sequentially from the inside to the outside; the conductive parts include electrodes and wires; the electrodes and the wires are electrically connected; the electrodes are embedded in the heat conduction layer; the wires extend from the electrodes to the outside of the heat conduction layer; the purification layer is embedded with EM bacteria culture agent, EM bacteria and graphite oxide; the preparation method includes: purification solution preparation step; heat insulation layer forming step; heat conduction layer forming step; transition layer forming step; purification layer forming step; into the water to be purified; the purification rope uses microbial immobilization technology to purify river sewage, avoiding the constraints of microbial space competition, easy loss of high-efficiency bacteria, and environmental temperature constraints, and enabling microbial immobilization technology to exert its high-efficiency removal Advantages of pollution.

Description

Technical field [0001] The present invention relates to a water purification rope, their preparation and their use, belonging to the field of water purification technology. Background technique [0002] Shortage of water resources, is one of the world's water-poor countries. With the rapid economic and social development of China, by industrial waste water, agricultural waste water, domestic wastewater pollution is getting worse, to human life, health, it had a tremendous impact. Water pollution also make our water shortage problem worse. Biological fixation technology is an emerging technology in the field of modern biotechnology. Immobilized technique is the use of chemical or physical positioned in the microorganisms or enzymes defined spatial region is not allowed to become suspended in the water still retain the biological activity, the method can be repeatedly used. Compared with the conventional biological treatment suspension, the advantages are immobilized technique: a c...

AI Technical Summary

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
