Intelligent control integrated system for circulating water treatment

Abstract

The invention discloses an intelligent control integrated system for circulating water treatment, and belongs to the technical field of fish culture. The circulating water treatment system is formed by a culture pond, a water pump pond, an overflow filtration combined pond, a filtering basin, a sterilizing pond, a biological filter, and an aeration oxygenation pond which are in sequential and communicating arrangement; and a dissolved oxygen content stabilizing device and a slow flow net cylinder are also arranged. The beneficial effects of the system are that remained fish food and fish excreta precipitated at the bottom of the culture pond can be discharged from the pond bottom; primary purification is performed on water to be treated by adopting the overflow filtration combined pond, workloads of a micro filtration device and a biological filter are alleviated, purification effects are improved, and service life is prolonged; the dissolved oxygen content can be monitored and supplemented in real time by adopting the dissolved oxygen content stabilizing device, thus the dissolved oxygen content in the culture pond is always kept at a required level, and growth environments of bred fishes are guaranteed; and an intelligent circulating treatment device of the system can be suitable for high-density and intensive culture of cold water fishes, and the yield and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to an integrated system for processing and utilizing intelligently controlled circulating water. Background technique [0002] Most of the current farmed fish are cultured in ponds, the water surface is large, and the water quality is difficult to control. Due to the input of bait, fish excrement and various slag enrichment, etc., the feed that sinks into the bottom of the pond quickly rots and deteriorates, resulting in the deterioration of the water environment of the fish pond. Water quality needs updating. Existing method is to dig water inlet ditch and drainage ditch to change water. Inlet ditch and drainage ditch in this method for changing water all are arranged on the top of fishpond wall, can only change the water quality of fishpond top, and the dirt of bottom can't be processed. [0003] As a result, a circulating water treatment system has emerged. A typical circ...

Problems solved by technology

[0004] However, the construction and operation costs of the existing circulating water treatment system are very high, which is a technical bottleneck restricting the further popularization and application of the industrial circulating aquaculture production mode.

[0005] At the same time, in the existing aquaculture circulating water treatment system, the filtration efficiency per unit volume of the physical purification device is low, and the load of the biological purification device is relatively large; in order to meet a certain residence time, the biological purification device occupies a large area, and the mass transfer characteristics of biological purification are poor. low processing efficiency
