Description
Technical field
The present invention relates to the process field of aquiculture sewerage discharge, various fresh water, brackish water and sea are especially adapted for use in
It is fresh temporarily that the aquaculture wastewater of aquatic organism, fresh water and sea-farming sewage, fresh water and seawater view and admire biological cultivation sewage, seafood and river
Support, the sewage discharge of the fresh transport of seafood and river processing.
Background technology
At present, breeding way is intensive culture pattern and industrial aquaculture pattern by pervious extensive cultivation, half intensive culture mode development,
But due to the economic benefit that covets, cultured area is continuously increased, cultivation density is continuously improved, and breed variety is excessively single, makes
The balance of natural ecosystems is broken in aquaculture system, and self-pollution is serious, produces substantial amounts of aquaculture wastewater.Aquatic products is supported
Broad-spectrum antibiotics are abused during growing to control the generation of disease, the resistance to the action of a drug of bacterium is added, more destroys aquaculture
The balance of waters normal bio fauna, so that forming vicious circle.Main pollutant has ammonia nitrogen, nitrous in aquiculture sewerage
Hydrochlorate, organic pollution, phosphorus and fouling organism.Aquiculture sewerage not by it is any processing be just directly discharged into river, river, lake,
The natural water bodies such as sea, make that eutrophication of natural water, antibiotic be exceeded, substrate ruins and induces a large amount of numerous of the pathogenic bacteria such as vibrios
Grow, cause disease frequent so that the ecosystem of natural water body is destroyed, and the ecosystem is unbalance, causes the disease-resistant of aquatic organism
Power reduces, and is more easy to infection pathogen.Currently, aquiculture sewerage processing is main uses：Physical technique, such as largely change water, aeration,
Filtering, precipitation, absorption, air supporting etc.；Chemical technology, such as flocculation, neutralization, complexing, redox, ozonization；Biotechnology,
Photosynthetic bacteria, Bacillus, actinomyces, more bacterium complex microorganism preparations, aquatic is added or cultivated such as in aquiculture sewerage
Plant, vegetables, flowers etc.；But these technologies are there are waste water resource, high energy consumption, system complex, it is cumbersome the problems such as, and
It is on the rise with the pollution of fishery water, substantial amounts of germ, virus, parasite, organic matter, antibiotic, a huge sum of money is incorporated in water
Belonging to and other harmful substances are very difficult to remove, aquiculture sewerage is arbitrarily discharged without processing, serious pollution natural water body,
So the problem of restoring nature after the bactericidal purifying of aquiculture sewerage is badly in need of solving.
The high speed development of culture fishery at present, the random discharge of breeding wastewater, natural water receive serious pollution,
So aquiculture sewerage discharge has to pass through processing.The processing method of traditional aquiculture sewerage discharge is mainly by heavy
Shallow lake pond removes the solid dirt do not allowed, and the harmful substances such as the ammonia nitrogen of water removal, nitrous acid are gone in biofilter, and ultraviolet and ozone carry out
Sterilization.There are the shortcomings of processing time is long, efficiency is low, high energy consumption, cumbersome, and regular maintenance is complicated.As aquaculture is dirty
The pollution getting worse of water, sewage quantity is more and more, and traditional aquiculture sewerage discharge treatment method cannot meet to work as
Preceding needs.It is badly in need of a kind of processing time is short, efficient, energy consumption is low, easy to operate, the simple aquiculture sewerage of regular maintenance
The processing method of discharge.
The content of the invention
In order to solve the treatment technology deficiency of existing aquiculture sewerage discharge, the present invention provides dirty for aquaculture
The processing method and equipment of water discharge, this method can not only kill germ, virus, parasite in water, reduce ammonia nitrogen and nitrous
Hydrochlorate concentration, goes soluble organic, antibiotic, the harmful substance such as heavy metal in water removal, also carries out reduction treatment to water body, make
The approximate free of contamination natural water body of water after processing；Equipment using modularized design is simple in structure, processing speed is fast, it is efficient,
Energy consumption is low, operation is easy, can also accurately be finely tuned according to various regions different quality and processing standard.
The present invention solves the technical solution that its technical problem uses：
To achieve these goals, the present invention provides a kind of processing method for aquiculture sewerage discharge, wherein,
Include the following steps：
Step A, the aquiculture sewerage of aquaculture pond bottom discharge, by precipitating filter plant preliminary purification, removes
The dirt not soluble in water such as suspended particulate and excrement；
Step B, aquiculture sewerage passes through cleaning equipment, removes ammonia nitrogen, nitrite, heavy metal, antibiotic in water removal
Etc. harmful substance and sterilize；
Step C, aquiculture sewerage passes through reduction apparatus, goes impurity tiny in water removal, colloid protein to be formed cotton-shaped
Precipitation, unnecessary cation and Strong oxdiative thing, the aquiculture sewerage for completing purification reduction treatment are directly discharged into by water outlet
The natural water bodies such as river, river, lake, sea.
Step A is specifically, aquiculture sewerage is carried from the bottom center sewage draining exit discharge of aquaculture pond by water pump
Rise, enter precipitation filter plant by water inlet c, primary purifying is carried out to aquiculture sewerage, water body first passes through water spray duckbilled

Matter, then aquiculture sewerage by precipitation process enter lautertuns by unrestrained water baffle, pass through filter media, removal
Tiny material not soluble in water in water, the aquiculture sewerage after filtering is entered by flow apron b and water level baffle b to catchment
Groove b, finally flows out from the water outlet c of catch basin b bottoms, completes preliminary purification processing, and the dirt isolated enters garbage pool, can
Recycled with working process as vegetable fertilizer；
Step B is carried out deeply net specifically, enter cleaning equipment by water inlet a by the aquiculture sewerage of step A
Change, cleaning equipment is made of cation generator and hydroxyl radical generator, and cation and hydroxyl can be produced by electrolysis
The Strong oxdiative thing such as free radical, cation and Strong oxdiative thing synergistic effect, can more quickly and efficiently kill bacterium in water, arc
Bacterium, virus, algae, parasite, reduce ammonia nitrogen and content of nitrite in aquiculture sewerage, remove in water body can be dissolved with
The harmful substances such as machine thing, antibiotic and heavy metal, aquiculture sewerage successively flow through cation generator and hydroxyl radical free radical hair
Purified treatment is goed deep into raw device, completion, and aquiculture sewerage is flowed out by water outlet a；
Step C by water inlet b by the aquiculture sewerage of step B specifically, enter reduction apparatus, by spray tube
Into reduction cell, Air Exposure carries out water body by nanometer aeration disk first in reduction cell, aeration can accelerate water body
Flocculation reaction, forms tiny suspended particulate and colloid protein that aquiculture sewerage produces in step B purification process cotton-shaped
Precipitation, then carries out reduction treatment by multilayer reducing medium to water body, removes aquiculture sewerage and is produced in aeration process
Flocculent deposit, while adsorb cation unnecessary in water, remove unnecessary Strong oxdiative material, revert to aquiculture sewerage
The state of approximate natural water, the aquiculture sewerage by reduction treatment flow into catch basin by flow apron a and water level baffle a
A, the aquiculture sewerage for finally completing purification reduction treatment are directly discharged into the natural waters such as river, river, lake, sea by water outlet b.
