Material and method for biologically purifying water body by using carbon nano-tube

Abstract

The invention relates to a material and method for biologically purifying a water body by using a carbon nano-tube, belonging to the technical field of environment friendliness and environment control. The material mainly comprises ash residues or plant ash from a biomass power plant, cement, sand or gravels, a carbon nano-tube, a photocatalyst and bacillus. The method comprises the steps of firstly, fixing and protecting microbial bacillus by using a granulation method; then, uniformly mixing the ash residues or plant ash generated after combustion in the biomass power plant, the carbon nano-tube, the photocatalyst, the sand or gravels, the granulation protected microbial bacillus and the high-standard cement, stirring the mixture, and pressing the mixture into a biomass purified brick by using a forming and brick making machine. The eutrophic water is subjected to purification treatment by using a technology and materials including a nanotechnology, plant ash residues, microbial bacteria and the like which are beneficial to environment protection, not only is the purification effect good, but also the environment protection property is considered, meanwhile, the initial investment is low, the maintenance and management costs are low, the relatively high cost performance is achieved, and the method is an optimal application technology capable of continuously taking effects.

Description

technical field [0001] The invention relates to a carbon nanotube (CNT) material and method for biologically purifying water, and belongs to the technical field of environmental protection and environmental governance. Background technique [0002] Eutrophication of water body refers to the phenomenon that the main nutrients nitrogen and phosphorus content in water body increase, which leads to the excessive reproduction of plankton. There are many reasons that affect the eutrophication of water bodies, and the main reason for the current cyanobacteria outbreak is caused by man-made eutrophication. With the development of the national economy and the improvement of people's living standards, as well as the development of cities and industries in my country in recent years, the extensive use of pesticides and fertilizers, the destruction of vegetation, the erosion of soil and water into the lake, etc., the nutrients discharged into the water body continue to increase, making ...

Problems solved by technology

Physical algae control generally adopts methods such as fishing by boats, sonic vibration, and water scour. The disadvantage is that it takes a long time and requires a lot of investment, making it difficult to implement.

Chemical algae control generally adopts sulfuric acid ketone method or adding promatriptide, calcium compound, aluminum compound and modified clay to local water bodies. Chemical killing can only solve the problem in a short time, but it will bring a series of negative effects. It is very likely to cause secondary pollution
