工厂化循环水养殖系统中 pH 维持系统研究
Study on pH maintains system in the factory recirculating aquaculture
摘要
Abstract
In order to accurately regulate the pH of recirculating aquaculture systems , and build a suitable fish growth environment , we set up a new pH maintain system .The system adopts a new control algorithm , through using the method of continuous adding alkali into aquaculture ponds to maintain the pH of water at a stable value.This test set target the values of pH at 7.4, and combined PID, TCP, anticipation and various calculation algorithms to change metering pump output flow through using configuration software .Through injecting NaHCO 3 solution by metering pump continually , it could balance the consumption of alkali in water and make the pH stability for a long time in the range of 7.4 ±0.01.The pH maintain system could realize the pH of precise control in the recirculating aquaculture system , and keep the stability of water quality .It had important significance of promoting the healthy growth of fish .关键词
