Description
Technical field
The invention belongs to aquaculture fields, and in particular to a kind of purification process of aquiculture waste water.
Background technique
Intensive aquaculture rapidly develops both at home and abroad in recent years, and China is more swift and violent, and cultured output has accounted for generation
2/3rds or so of boundary's cultured output.The current aquaculture in China is in one from traditional high yield stocking model to scale
Change the Historical Transformation phase of cultivation, quality and benifit transformation, but since China's aquaculture is still by the way of drawing arrange greatly greatly, both greatly
Ground consumes water resource, and the pollutant that the feed remnants and excreta that launch in aquaculture process are formed, to water body,
Sediments cause pollution, so that breeding water body eutrophication increasingly, causes more surrounding body environment and ecological environment
Carry out bigger harm.If Ecological Disposal and recycle to breeding wastewater, then with consumption of natural resource (water resource),
The culture fishery that environment is cost is polluted, is difficult to keep a foothold under the impact of the production tide of conservation culture from now on.
Compared with city domestic sewage and industrial wastewater, aquaculture water pollution has the characteristics that its uniqueness, i.e. potential pollution
Object content is low, a displacement is big, has differences with common Lu Yuan sewage, and processing difficulty greatly increases.Nitrogen phosphorus in breeding wastewater
Nutritional ingredient, dissolved organic matter, pernicious gas (such as hydrogen sulfide), suspended matter and pathogen are the emphasis of processing.Existing skill
In art, the waste water that aquaculture generates mainly is directly emitted, and the processing method water resource waste is big, and periphery easy to pollute
Environment.
In view of this, the present invention proposes a kind of purification process of new aquiculture waste water, the technique by after wastewater treatment,
It can be directly re-used for aquaculture.
Summary of the invention
The purpose of the present invention is to provide a kind of purification process of aquiculture waste water, which, can by after wastewater treatment
It is directly re-used for aquaculture.
To achieve the goals above, used technical solution are as follows:
A kind of purification process of aquiculture waste water, comprising the following steps: after handling aerating wastewater, carry out at probiotics
Reason.
Further, it before the waste water carries out Air Exposure, first filters.
Further, the probiotics includes: at least one of photosynthetic bacteria, lactic acid bacteria, bacillus.
Further, the probiotics includes: photosynthetic bacteria, lactic acid bacteria and bacillus.
Further, the temperature of the probiotics processing is 25-35 DEG C.
Further, the temperature of the probiotics processing is 30-35 DEG C.
Further, the probiotics treated waste water, can be re-used for aquaculture.
Compared with prior art, the beneficial effects of the present invention are:
1, a kind of purification process of aquiculture waste water of the present invention, the technique mainly pass through Air Exposure, will have
Evil gas removal, and achieve the effect that oxidation；Along with probiotics is handled, the harmful bacteria in sewage is removed, effectively purification aquatic products
The waste water generated is cultivated, waste water is allow to be re-used for aquaculture.
2, a kind of purification process of aquiculture waste water of the present invention, the simple process and low cost can be purified effectively
Sewage recycles waste water again, reduces aquaculture cost.
Specific embodiment
In order to which the present invention is further explained, a kind of purification process of aquiculture waste water, reaches expected goal of the invention, below
In conjunction with preferred embodiment, to a kind of purification process of aquiculture waste water proposed according to the present invention, specific embodiment, knot
Structure, feature and its effect, detailed description is as follows.In the following description, different " embodiment " or " embodiment " refers to different
It surely is the same embodiment.In addition, the special characteristic, structure or feature in one or more embodiments can be by any suitable form groups
It closes.
Before elaborating a kind of purification process of aquiculture waste water of the present invention, it is necessary to what is referred in the present invention
Raw material and method etc. are described further, to reach better effect.
Aeration, refers to the oxygen in air forcing the process shifted into liquid, the purpose is to obtain enough dissolved oxygens.This
Outside, aeration also prevents suspended substance in pond from sinking, and reinforces the purpose that organic matter is contacted with microorganism and dissolved oxygen in pond.To protect
Microorganism is under conditions of having sufficient dissolved oxygen in card pond, to the oxygenolysis of dirty Organic substance in water
According to the principle of microecology, in probiotics, anaerobism, which is become reconciled, feeding microorganism and deposits, the useful object generated in growth
Matter and its secretion become the mechanism and raw material grown respectively or each other, by mutual symbiosis Relationship With Proliferation, form one
The microecosystem of a stabilization and complexity, can accelerate the degradation to organic matter, and play multi-functional.Therefore, as long as stringent control
Temperature processed gives full play to the symbiosis proliferation function of each flora, maintains good microecosystem, can preferably complete pollutant drop
The complex processes such as solution.
