Suspending floccules generating device used for controlling quality of industrial aquatic water of prawns

Abstract

The invention relates to a suspending floccules generating device used for controlling the quality of industrial aquatic water of prawns and a method for controlling the quality of the industrial aquatic water of the prawns by using the device. The method is characterized by comprising the steps of preparing the suspending floccules generating device, placing the suspending floccules generating device into a culture pond, selecting and placing bagasses of suitable particles sizes after being disinfected into the device, and ventilating to flowenable the bagasses flow circularly; inoculating and cultivating by the activated bacillus powder, supplementing the bagasses and the bacilli every about every 10 days, adjusting the output flow rate by rotating a flow controller, adjusting the particle diameterssizes of the bagasses by the sizes of screen meshes on the flow controller, quantitatively controlling the bagasses, less than the sizes of screens of the screen meshes, adhered with the bacilli less than the screens of the screen meshes to flow out of a round hole in the top of a reactor, generating the floccules in an oriented way, and controlling the quantity of the bacilli in the water, so as to realize an aim of controlling the quality of the aquatic water. The suspending floccules generating device provided by the invention has the advantages of being low in design cost, low in energy consumption and high in purification efficiency, is free from pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of mariculture, and in particular relates to a suspended flocculation generating device for adjusting and controlling the water quality of industrialized culture of prawns. Background technique [0002] During the high-density culture of prawns, a large amount of organic matter such as residual bait and feces will be produced. Especially in the middle and late stages of the culture, the water quality will easily deteriorate, leading to the outbreak of diseases, which will eventually lead to a reduction in the production of prawns, and even the failure of the culture. At present, there is a lack of a method that can not only keep the beneficial components in the pond from being lost, but also reduce the entry of pathogens into the pond, improve the water quality of the pond, and save costs.

[0003] Chinese patent (CN 103896410 A) discloses a biofilm-based aquaculture wastewater treatment system. Bagasse is screened with a sieve and placed in a mesh bag and placed on a support. Biofilm is cultivated by inoculating different strains, and the effect of microorganisms is used to improve Water quality, but it takes 25-30 days for the biofilm to mature, which is a long time, and the bagasse is piled up, which reduces the specific surface area for microorganisms to attach to. control
