Method for constructing purifying water by constructing microbe film in pond by using elastic filler

Abstract

The invention relates to a method for purifying water by utilizing elastic filler to build a microbial film in a pond, and is characterized in that: the elastic filler is firstly hung at the center of an aquiculture pond, and the upper end of the elastic filler is fixed by a rope, while the lower end thereof is fastened up by a heavy article; when the water temperature reaches 20-30 DEG C, the elastic filler is hung in the water of the pond, meanwhile, micro-ecological agent is sprinkled, the dosage is as follows: 300-500g of micro-ecological agent is applied to every mu water surface of the aquiculture pond with the depth of one meter for every 7-10 days, and the solidified microbial film can be formed in 25-35 days; 300-500g of micro-ecological agent is applied to every mu water with the depth of one meter for every 25-30 days after the solidified microbial film is formed. The method of the invention introduces the elastic filler into the water of the pond, takes the indigenous microorganisms in water and the introduced exogenous microorganisms as microorganism sources to build the solidified microbial bacteria film of the pond, thus realizing efficient in situ bioremediation ofthe water environment, reducing water exchange rate, saving water resources, relieving the ecological pressure on the outer environment caused by aquiculture sewage and enhancing the quality and benefits of the pond aquiculture.

Description

technical field [0001] The invention relates to a method for purifying water quality by constructing a microbial membrane in a pond by using elastic fillers, and specifically belongs to the technical field of aquaculture. Background technique [0002] Because of its simple structure and strong controllability, the pond ecosystem has become the main water body of aquaculture production, and occupies a pivotal position in the fishery economy of our country. Most of the existing pond cultures adhere to the traditional farming model, that is, high-density stocking, a large amount of fertilization and feeding to obtain high yield and high efficiency. Under this farming model, the content of organic matter, nitrogen, and phosphorus in the pond water increases sharply, the water quality deteriorates, and the pollution becomes increasingly serious. In order to improve water quality and prevent diseases, the main technical means at present are to increase the amount of water exchang...

Problems solved by technology

On the one hand, changing water wastes water resources, on the other hand, it may cause pollution to the external environment of breeding

Although the use of chemical water treatment agents has certain effects, the effects are often short-term, unstable, and costly

At present, the application of micro-ecological preparations mostly uses the free cells of microorganisms to directly add to the water body. Because the survival and vitality, colonization and loss of free cells in the water body are greatly affected by environmental conditions, the purification effect on the water body is often not stable. , and sometimes even cause secondary pollution

Therefore, the above-mentioned methods all have certain defects.
