AI Technical Summary

Technical Problem

The existing circulating water aquaculture system responds slowly when adjusting the circulation volume of water, and the adjustment results are lagging, which is not conducive to the stable operation of the system.

Method used

By setting up a liquid level sensor in the micro filter, the liquid level data of the clean water chamber is collected in real time, and combined with the backwashing times and water consumption of the backwashing pump, the control system is used to determine whether the flow rate of the circulating pump needs to be adjusted to achieve real-time adjustment of the water circulation.

Benefits of technology

Real-time adjustment of water in the circulating water aquaculture system is achieved, with fast response speed and no lag in adjustment results, avoiding the problem of mismatch in water quality treatment and ensuring the stable operation of the system.

Abstract

The invention relates to the field of aquatic feed, in particular to a recirculating aquaculture system and a flow control method thereof. The invention discloses a flow control method of a recirculating aquaculture system. The flow control method comprises the following steps: collecting liquid level data of a clear water bin in a microfilter, and judging whether the liquid level data of the clear water bin in unit time exceeds a set threshold value or not so as to determine whether a control system starts a backwashing pump to carry out backwashing on the microfilter or not. And collecting the backwashing times of the backwashing pump in unit time and judging whether the backwashing times exceed a set threshold value II or not. And collecting the water consumption of the backwashing pump during backwashing in unit time, and judging whether the water consumption exceeds a set threshold value III or not. Whether the circulation amount of water in the circulating water culture system needs to be regulated or not is judged according to the number of times of backwashing and the water consumption. By means of the flow control method, the circulation amount of water in the circulating water aquaculture system can be accurately and rapidly adjusted, the response speed of the whole adjusting process is high, and the adjusting result does not have hysteresis.
