Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a self-maintenance and inoculation-free method and a special device for a biological filter in a circulating aquaculture system. First, solve the problem of self-propagation of water purification microorganisms in the biological filter of aquaculture circulating water through backflow; second. 2. By adjusting the return flow to balance the content of water purification microorganisms in the aquaculture circulating water biofilter; third, by setting multiple return points to balance the problems of various water purification microorganisms in the aquaculture recirculation water biofilter

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0016] Such as figure 1 As shown, the water inlet end of the circulation pump 4 is connected to the buffer adjustment tank 3 , and the water inlet end of the buffer adjustment pool 3 is connected to the culture pond 1 through the return pipe 2 . The aquaculture circulating water enters the pre-stage biofilter 6 through the circulation pump 4 and the water supply pipe 5 for biological filtration, and the pre-stage biofilter 6 is provided with a filler 7 for attaching water purification microorganisms.

[0017] A mid-section return pipe 8 is provided at the water outlet of the pre-stage biofilter 6 to divert part of the circulating water to the buffer adjustment tank 3 for recirculation through the circulating pump 4, and this part mainly returns saprophytic fungi free in the water. The water outlet end of the middle return pipe 8 installed with the first f...

Abstract

The invention discloses an automatic maintenance inoculation-free method for a biological filter of a circulating water culture system and a special device. Water purification microbes do not need to be inoculated in the operational process, the water purification microbes in the biological filter are continually propagated and regenerated by means of refluxing, and various free water purification microbes in the water are refluxed to the front end to play a role in water purification microbe inoculation, so that the biological purification capacity of the biological filter is kept and enhanced, and automatic maintenance and inoculation-free purposes of the biological filter are fulfilled; and the method is mainly applied to a factory circulating water culture water treatment biological purification system.

Description

technical field [0001] The invention relates to a self-maintenance and inoculation-free method for a biofilter in a circulating aquaculture system. The invention also relates to a special device for implementing said method. Background technique [0002] During the initial water intake debugging stage and daily operation of the recirculating aquaculture system, the first thing to encounter is the cultivation and domestication of water purification microorganisms, and then the daily management and maintenance. Poor management of any of these links will lead to poor microbial growth and failure of water purification. [0003] Since there are disinfection and sterilization devices before and after the circulating aquaculture water treatment, it is necessary to maintain the vitality of the system by inoculating water purification microorganisms and maintain the concentration of water purification microorganisms in the system, which puts forward the daily management and operatio...
