Description
Technical field
The present invention relates to a kind of methods of breeding wastewater decoloration, belong to technical field of waste water processing.
Background technology
Breeding wastewater mostlys come from swine excrement, pig urine and pigsty flushing water during large-scale cultivation.At biology
The pollutant load of the waste water of reason, waste water is substantially up to standard, but the coloration of treated waste water is compared with deep, biodegradability is poor, directly row
It puts to receiving water body, the pollution for not accommodating environment of sense organ can be caused.It is said from the wastewater processing technology applied at present, it can be effective
The method of removal chroma in waste water has absorption method, Coagulation Method, bioanalysis, membrane separation process, chemical oxidization method level-one electric flocculation method etc..Its
Middle chemical oxidization method have technical maturity, at low cost, treatment effeciency is high, high-quality.The principle of chemical oxidation decoloration is to utilize oxygen
Agent destroy waste water in substance that show color unsaturated group and chromophoric group and reach decoloration purpose.With strong oxidisability
Decolorising agent also have the function of decompose substance that show color, achieve the purpose that thoroughly to decolourize.Therefore chemical oxidization method can be applied to difficulty
It is handled with the waste water decoloring using the decoloration of other methods.But the decolorising agent main ingredient that current chemical oxidization method uses is hypochlorous acid
Calcium, sodium hypochlorite, hypochlorous acid etc., although therefore waste water coloration after decoloration it is low, water quality contains a small amount of Active Chlorine, and
Active Chlorine has strong toxicity to biological cell, can endanger water plant and animal, and threaten the health of the mankind.
Invention content
The technical problems to be solved by the invention：The Active Chlorine that is also easy to produce in decolorization for current breeding wastewater or
The a large amount of sludge generated after decoloration, the problem of causing environmental pollution, the present invention provides a kind of methods of breeding wastewater decoloration.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of method of breeding wastewater decoloration, this method comprises the following steps：
（1）Cultivation water reuse filter screen is filtered, bulky grain solid impurity is removed, filtrate is sent into cement pit, to
The additive of filtrate quality 10~15% is added in cement pit, is heated, heating temperature is 60~70 DEG C；
（2）After heating, cooled to room temperature is stood, and filtrate is collected in filtering, by filtrate feeding amount culture pond, culture
Bottom of pond portion is composite soil, then plantation hornwort and duckweed pass through after filtrate stands 10~15h in culture pond into culture pond
Culture pond bottom excludes the liquid in culture pond, collects and excludes liquid；
（3）Liquid will be excluded to purify by clarifier-tank, the temperature of clarifier-tank is maintained at 45~50 DEG C, by the liquid of purification from
Clarifier-tank bottom is flowed out, and is discharged after outflow, you can complete the decoloration of breeding wastewater.
The step（1）Middle additive is by potassium carbonate and ammonium hydrogen carbonate in mass ratio 4:3 mix.
The step（2）The each feeding amount of middle filtrate will flood composite soil completely, and be higher by 7~10cm of composite soil.
The step（2）Middle composite soil is by fertile soil, quartz sand and peat soil in mass ratio 2~4:8:5 mix.
The step（2）The plantation amount of middle hornwort be per 10~20 plants of square meter, the plantation amount of duckweed be per square meter 20~
23 plants.
The step（3）Middle clarifier-tank is internally provided with mixed fillers, excludes liquid and is flowed from top to bottom, passes through clarifier-tank
It flows out bottom.

Modified activated carbon.
Compared with other methods, advantageous effects are the present invention：
The present invention is removed by filtration wherein big grain size solid impurity, and additive is added and is neutralized to the acid in waste water, simultaneously
Moieties therein are settled, in culture pond, using microorganism abundant in composite soil to having in breeding wastewater
Machine matter is degraded, first, reducing the coloration in breeding wastewater, second is that the activity of waste water can be improved, improves automatical cleaning ability,
It will pass through to plant and plant at composite soil surface, in order to avoid the accumulation of nutriment process or harmful substance organic matter is old
Object carries out it using decomposition, and by the effect of plant, can further purify water, and avoids the production of harmful sludge
It is raw, it is purified finally by mixed fillers, by using activated carbon as base material, using copper nitrate, aluminium isopropoxide etc. as golden
Belong to donor, makes metal particles deposition in activated carbon surface, increase the adsorption-decomposition function ability of activated carbon, and using in metal member
Oxygenating is carried out to waste water under the action of element, further water quality is purified, to effectively handle breeding wastewater.
