Decontamination device used for cultivation

Abstract

The invention discloses a decontamination device used for cultivation. The decontamination device comprises a booster pump, a high-pressure tank body and an air flotation bucket, wherein the booster pump is provided with a clear water suction hole and an air suction hole; the outlet of the booster pump communicates with a bottom outlet of the high-pressure tank body; the outlet of the high-pressure tank body is connected with a pressure releasing device; the pressure releasing device communicates with the air flotation bucket; the top of the air flotation bucket is connected with a bubble collection device; the bubble collection device is provided with a contamination draining pipe; and the upper part of the air flotation bucket is provided with a water discharging pipe. A use method of the decontamination device is that a cultivation water body and air form an air-water mixture under a function of the booster pump, then, the cultivation water body flows into the high-pressure tank body, a great quantity of air is dissolved in the water body under a high-pressure function and is injected into a water inlet pipe of the air flotation bucket through the pressure releasing device, tinybubbles are released under a low-pressure environment, and tiny particles and soluble pollutants are adsorbed to enter the bubble collection device to achieve a purpose of water treatment. The decontamination device has the advantages of low energy consumption, a large tiny bubble yield, evenness in distribution and high suspended particle and protein removal efficiency.

Description

technical field [0001] The invention relates to the field of aquaculture water body treatment, in particular to a decontamination device for aquaculture. Background technique [0002] At present, the aquaculture treatment system usually includes multi-stage treatment units, but the reduction is the core principle of the water treatment system design, that is, through various technologies such as rapid sewage discharge, solid-liquid separation, etc., the residual bait and feces and other particulate matter generated during the aquaculture process are discharged from the system. , Reduce the load of pollutant treatment. According to different treatment objects, the reduction treatment units can be divided into the following two categories. The first category is to remove sedimentable particles such as residual bait and feces. This type of treatment unit has a simple structure and operating conditions but the reduction effect is obvious, such as: Vortex resolution separator, s...

Problems solved by technology

[0003] The microfiltration machine uses physical filtration to remove suspended particles, with high removal efficiency and stability, but it is not suitable for fine particles (<35μm). The aquaculture industry usually uses protein separators to remove fine particles and some proteins. The structure and operation of protein separators are simple and reliable , and the effect is relatively stable, easy to maintain

But also there are following deficiencies in actual effect and application: (1) the air bubble particle size that various methods produce in existing protein skimmer is bigger and distributes unevenly, and fine particle and protein removal efficiency are not high, and supporting multiple Jet pump, high energy consumption; (2) In the freshwater aquaculture system, the bubbles produced by the low viscosity of freshwater are large and small, and have poor adsorption capacity for particulate matter and protein, and the protein separator has almost no effect in freshwater aquaculture; (3) Seawater Ozone dosing in the protein skimmer in farming is often not fully utilized due to uneven mixing and there is a problem of ozone residue
