Description
Technical field
The present invention relates to technical field of sewage, more particularly to a kind of fishery cultivating sewage water treatment method.
Background technology
Fishery cultivating sewage belongs to the high concentration organic sewage containing a large amount of pathogen, is discharged directly into water body or storing place
Point is improper, is entered water body by rain-out, it would be possible to cause the severe exacerbation of surface water or quality of groundwater.Current fishery is supported
Growing the main methods of water body has：Water purification agent processing, Anaerobic Treatment, Aerobic Process for Treatment.But water purification agent processing is time-consuming long, water purification
Agent belongs to pollution source using the rear overwhelming majority and can only be for the processing of partial contamination material, it is necessary to other supplementary mode
Purification can finally be realized.The characteristics of Anaerobic Treatment be take up an area less, energy requirement it is low, biogas can also be produced, but be processed into
This height, handles complex operation, and the methane quantity produced for the little sewage for the treatment of capacity is small to be unable to reuse, there is potential safety hazard and makes
Into secondary pollution.The general principle of Aerobic Process for Treatment be utilize microorganism decomposing organic matter under aerobic condition, it is simultaneously synthesizing itself
Cell (activated sludge), biodegradable organic matter can be finally fully oxidized as simple inorganic matter, including activated sludge,
Catalytic oxidation and biological rotating disk etc..High treating effect is characterized in, operating cost is moderate, but floor space is larger, and processing
During easily produce stench etc..Therefore, need a kind of concise in technology badly at present, it is easy to operate, to fishery cultivating wastewater treatment efficiency
The low method of good, cost.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.
The content of the invention
The present invention is directed to problem of the prior art, invents a kind of processing method of fishery cultivating sewage, it is intended to obtain one kind
Low, good to the aquaculture wastewater treatment effect method of concise in technology, easy to operate, cost.
To achieve the above object, the technical scheme that the present invention is provided is as follows：
A kind of processing method of fishery cultivating sewage, comprising：It is 7~10m by pretreated sewage control flow3/ h leads to
Enter to decontaminate in pond, the absorption stone after some soda acids is contained in cesspool, the sewage of decontamination pond outflow carries out subsequent treatment, i.e.,
；Wherein, the absorption stone after described soda acid is the erratic deposition rock that specification is 2~5cm of radius, is soaked in alkaline solution
Bubble 1~3 hour, is then placed in weak acid solution and soaks 10~30 minutes, takes out, dries, produce.Sedimentary rock is entered in the present invention
Again through peracid treatment after row alkaline solution treatment, it is possible to increase the density of sedimentary rock Hole, sedimentary rock is set to be inhaled as one kind
The rich nutritive material and the absorption stone of impurity contained in attached fishery cultivating sewage, improves the dynamics to sewage disposal and letter
The step of having changed desmear process.
Preferably, described alkaline solution is the ammonia spirit that mass percentage concentration is 3~11%.
Preferably, described weak acid solution is the citric acid solution that mass percentage concentration is 2~7%.
Preferably, described pretreatment is that sewage is passed through in standing pond, stands 3~5 days, large granular impurity and discarded
Thing sinks to the bottom or floated oilysewage surface, removes surface discarded object, flows into clarification sewage and is exposed to the sun in pond, is exposed to the sun 10~15 days.
Preferably, described subsequent treatment is to be discharged into Aerobic Pond from the water of decontamination bottom of pond portion discharge, by Aerobic Process for Treatment,
Produce.
Preferably, it is 50~100/m that described sedimentary rock, which delivers density,2。
Compared with prior art, the present invention has the advantages that：
Sewage water treatment method of the present invention can play effective dirty removal capacities, the absorption stone energy of use to fishery cultivating sewage
Targeting decontamination is played for pollutant present in aquaculture wastewater, more targetedly, and scavenging effect is strong, simplifies and decontaminated
Processing step in journey, reduces the risk that other extra stain remover inputs pollute to sewage secondary, reduces decontamination cost.
