System and device for treating water pollution by biological cultivation

Abstract

The invention relates to a system for controlling water pollution by microorganism culture, which is characterized in that the system is composed of crowded floating cages that are orderly arranged. Aquatic plants and fishes are placed in each cage, an aerating and supplementing machine is arranged on each cage, a wave generating machine is arranged in the middle of the cage, and the system is powered by local power generation or external power supply. The inventive system overcomes the worldwide problem of controlling large area water body pollution. The inventive system has very distinct and sustainable effect in wastewater treatment, especially urban household wastewater treatment. The system has the following advantages of: (1) environmental friendliness and sustainability; (2) changing from uninterrupted intensive investment of large-area water pollution controlling to once investment, and sustainable high output; (3) converting water pollutants to available precious resources; (4) providing a large amount of job opportunities; and (5) generating related industrial cluster and high-profit cycling economic chain. The inventive system can be not only used for water pollution controlling, but also for microorganism culture.

Description

technical field [0001] The invention relates to the technical field of biological breeding and sewage treatment, in particular to a system and device for biological breeding to control water pollution. Background technique [0002] Sewage treatment is still a worldwide problem. At present, the methods of sewage treatment can be roughly divided into three major technical routes: chemical method, physical method and biological method. The chemical method needs to add chemical drugs, and the drug itself contains harmful ingredients, so it is not suitable for use in large areas of water; the physical method consumes a lot of energy, costs high, and has limited effects. In recent years, the technology of biological treatment of sewage has more practical applications, and its effect is more obvious than that of chemical and physical methods. Biological treatment of sewage is to use the biological chain in the water and the relationship between organisms to grow and breed one or ...

Problems solved by technology

[0004] 2. There is no external man-made energy input in both methods, changing the energy structure of the water body itself, changing the activity direction of aquatic organisms in the water body and changing the biological chain of aquatic organisms in the water body;

[0005] 3. Closed aquaculture cannot fully and effectively absorb and decompose pollutants and harmful components of the water outside the closed cage, and under certain circumstances, it is necessary to put biological food into the water, causing new pollution;

[0006] 4. Open farming cannot effectively control the quantity, quality and harvest of organisms, resulting in the proliferation, loss of control and death of organisms, resulting in new pollution;
