Description
Technical field
The present invention relates to a kind of water treatment method and isolated plant thereof, particularly a kind of aquiculture recycled water air-float comprehensive treatment method and isolated plant thereof.Be mainly used in the industrial circulating water cultivating water treatment system.
Background technology
Because the fine suspension in culturing recirculated water is higher as colloid, Mierocrystalline cellulose, albumin, oily foam (shedding in the bait) and soluble proteins molecule content, and is totally unfavorable to follow-up water treatment.Existing water treatment method and associated processing device, since relatively poor to the specific aim of this special water quality, so can not adapt to the demand of aquiculture recycled water.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of above-mentioned existing water treatment method and device, and provide a kind of aquiculture recycled water air-float comprehensive treatment method and isolated plant thereof, by air supporting, precipitation and biochemical treatment, solve recirculated water fine suspension such as colloid, Mierocrystalline cellulose, albumin and the high problem of soluble proteins molecule content of culturing, culture the problem of the solid impurity that particle is bigger in the recirculated water, and the problem of culturing ammonia nitrogen in the recirculated water.
The present invention has adopted following technical scheme.
A kind of aquiculture recycled water air-float comprehensive treatment method is characterized in that: breed recirculated water at first enters and has the air supporting reaction tank of making bulb apparatus, and impurity formation foam, scum silica frost such as the suspended substance in the water, oily foam are separated; The reacted water of air supporting enters the three phase separation pond, and in the three phase separation pond, the solid impurity that particle is bigger sinks in the sewage sump at the bottom of the pond, drains by blow-off pipe; The scum silica frost that is held up by bubble flows into the collection foam dreg collecting slot on top, pond, discharges through row's foam scum pipe, and the biofilter material that clear water is then flowed through in the air supporting reaction tank carries out degradation of ammonia nitrogen, flows into next step operation through rising pipe afterwards and recycles.
A kind of aquiculture recycled water air supporting comprehensive treating process isolated plant is characterized in that: have water inlet pipe and be separated into three spaces with the body inside, comprehensive treating process pond of making bulb apparatus by twice separation body of wall, described separation body of wall top all has overflow port; The space of device front end is the air supporting reaction tank, and the space of rear end is the three phase separation pond, and collection foam dreg collecting slot is the 3rd space, and this collection foam dreg collecting slot is positioned at three phase separation pond upper rear end; Separation body of wall bottom between air supporting reaction tank and the three phase separation pond offers the backflow sewage draining exit, biofilter material is installed in the three phase separation pond, row's foam scum pipe is arranged on the collection foam dreg collecting slot outside, and rising pipe is arranged on middle side part outside the three phase separation pond, and blow-off pipe is arranged on three phase separation pond outer lower portion.
Positively effect of the present invention is: utilize the tiny bubble surface to adsorb to be mingled in various granular dirt and protein soluble in water in the water, separate and contract, implemented effective air supporting and handled.Adsorption is exactly that the solute of bubble surface is concentrated, the foam that removing forms on fluid surface, can remove the material that is concentrated, remove deleterious organic granular in the water fast, prevent that it from decomposing in water body, can be directly adsorbing and removing falls organism such as colloid, Mierocrystalline cellulose, albumin (can remove 80% in theory, in fact reach 50% and just can satisfy the requirement of culturing recirculated water) foam from water, scum silica frost is separated, but also total gas level of equilibrium water of air supporting.Bigger solid impurity solids precipitation discharges in the bottom simultaneously; Flow into next flow process behind the middle more clear water process biofiltration degradation of ammonia nitrogen, in culturing circulating water treatment, just reached rapid minimizing BOD like this
5, COD and ammonia nitrogen purpose.
The present invention also has the few and characteristics easy and simple to handle of power consumption.
