Example Embodiment

[0017] The present invention will be further explained below with reference to the drawings and specific embodiments.

[0018] Such as figure 1 Shown is a schematic diagram of the structure of the suspended floc generating device of the present invention. As shown in the figure: a PVC pipe with an outer diameter of 250mm and a height of 90cm is used as the reactor 2, and its upper and lower ends are open; a PVC pipe with an outer diameter of 110mm and a height of 70cm is used as the center pipe 4, and its upper and lower ends are also open. , Its outer diameter is smaller than the inner diameter of the reactor 2, and is placed in the reactor 2. The bottom of the reactor 2 is connected with a PVC pipe with an inner diameter of 250mm. Connector 2 7 has a height of 20cm, an outer diameter of 250mm, and a row of PVC pipes with a diameter of 5cm round holes 12 as the base 8. The top wall of the reactor 2 has two A row of circular holes 14 with a diameter of 5cm, connected with an in...

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 s...
