Abstract
The present invention relates to a kind of helotism bioreactor coupling artificial wet field facilities for treating sewage and its processing methods.The device includes inlet tank, bioreactor and artificial swamp；Inlet tank connects bioreactor by water inlet pipe, and intake pump is provided on water inlet pipe, is provided with inner cylinder in the middle part of bioreactor, bioreactor connects artificial swamp by outlet pipe；It is provided in artificial swamp into water partition, the artificial swamp is divided into wetland variation unit, ozonization unit and film process unit by partition.It the described method comprises the following steps: waste water to be processed is successively passed through into bioreactor and artificial swamp, light source and Aeration fan, qualified discharge or reuse after bioreactor and wetland variation unit, ozonization unit, film process cell processing are opened in reaction process.The present invention is using bioreactor coupling artificial wetland treatment aquaculture tail water and uses PLC overall-in-one control schema, solves the processing problem of such waste water.
Description
Technical field
The invention belongs to technical field of waste water processing, and in particular to a kind of helotism bioreactor coupling Manual moist
Ground sewage-treatment plant and its processing method.
Background technique
Aquaculture be most important component part in China's freshwater aquiculture, by water resource, land area lack etc. first
The multiple factors such as its factor and cultivation infrastructure are poor, environmental pollution is heavy, productivity decline influence, especially with intensive water
The fast development of aquaculture model is produced, water quality deterioration and discharge of wastewater directly constrain the sustainable development of aquaculture industry.It cultivated
The discharge of bait, the decomposition of residual bait, the generation of excreta and chemicals and the use of antibiotic etc. in journey, make to seek in water body
It supports substance, organic debris etc. to severely exceed, causes the Cultivated water ecosystem unbalance, disease is bred, and water body environment evil is exacerbated
Change degree.It directly utilizes or circulating and recovering breeding water body is very harmful to fish, it is necessary to just can be used as cultivation after processing and use
Water.Major pollutants in aquaculture tail water have ammonia nitrogen, nitrite, organic matter, phosphorus etc., and ammonia nitrogen is the excretion of aquatic animal
The final product that the itrogenous organic substances such as object and residual bait, excrement and animals and plants corpse decompose, be easy to cause water body to deteriorate, to cultivation
Animal generates toxicity.Nitrite has very strong toxicity to fish, its presence can lead to fish, the blood red egg of ferrous iron in shrimp blood
It is white to be oxidized to high-speed rail ferrohemoglobin, and the latter cannot deliver oxygen, to inhibit the oxygen carrying capability of blood, cause tissue
Anoxic, the decline of aquatic animal ingestion ability, in addition it is dead.Organic matter is mainly by residual bait, the metabolite of planktonic organism and cultivation
The excreta of animal, which decomposes, to be generated, and high organic content often results in water body deterioration, causes fish growth slow or even general pond or dead
It dies.
A large amount of research has been carried out to aquaculture tail water processing technique and has been answered currently, having more researcher both at home and abroad
With some farms can be filtered tail water and handle using biological ball or filter etc., but this mode can only filter out
The purpose of depollution is not achieved in large granular impurity in tail water；A small number of farms will use the equipment such as Protein Skimmer
To carry out purified treatment to tail water, however, these tail water are usually successively after several cleaning equipments with regard to direct emission at present
It goes out, can still there is more poisonous and harmful substance in treated tail water, biggish pollution still can be caused to environment.
Summary of the invention
In view of this, the present invention aquaculture tail water in the prior art processing be not thorough, poor processing effect aiming at the problem that,
A kind of device suitable for the processing of aquaculture tail water and corresponding processing method are provided.
In order to achieve the above object, the technical solution adopted by the present invention is that:
A kind of helotism bioreactor coupling artificial wet field facilities for treating sewage, it is characterised in that: including water inlet
Case, bioreactor and artificial swamp；The inlet tank connects bioreactor, the water inlet pipe by water inlet pipe
On be provided with intake pump, be provided with inner cylinder in the middle part of the bioreactor, bow font partition be provided in the inner cylinder,
The bow font diaphragm internal is provided with multiple aeration heads, and the bow font diaphragm internal is additionally provided with multiple light sources, institute
It is filled with helotism body in the inner cylinder stated, is provided with overflow weir, the photo-biological above the bioreactor
Reactor connects artificial swamp by outlet pipe；It is provided in the artificial swamp into water partition, the artificial swamp is logical
It crosses partition and is divided into wetland variation unit, ozonization unit and film process unit.
Optionally, there are gaps between the multiple lateral partitions and longitudinal baffle of the bow font partition, and described is multiple
Light source is set to the gap location of multiple lateral partitions and longitudinal baffle, and the light source is incandescent lamp or fluorescent lamp, intensity of illumination
Between 3000-10000lx, pH meter, temperature monitor are additionally provided in the bioreactor.
Optionally, the wetland variation unit sequentially consists of coarse filtration layer, hypothallus, fine sand layer and plant
Layer, the coarse filtration layer are mixed using gravel with haydite, and mixed volume ratio is gravel: haydite 3:1, the hypothallus are adopted
With stalk and active carbon, mixed volume ratio is stalk: active carbon 2-3:1, the layer of plants be selected from canna, calamus,
One of Chinese pennisetum, wild rice stem, reed are a variety of.
Optionally, the processing unit is additionally provided with PLC control system, and the PLC control system is for controlling system
The start and stop of the Inlet and outlet water, light source control, aeration control, ozone generating-device and film process unit of system, multiple aerations
Head connects Aeration fan by aerated conduit.
Optionally, it is provided with ozone generating-device in the ozonization unit, is arranged in the film process unit
There is ultrafiltration membrane, the ultrafiltration membrane material is one of polyvinyl chloride, polystyrene or cellulose acetate, membrane aperture 0.1-
0.3 μm, film wire percent opening is 80%-95%.
The invention also discloses a kind of method using above-mentioned apparatus processing aquaculture tail water, aquacultures to be processed
Tail water is pumped into bioreactor through intake pump, is controlled the temperature in bioreactor by pH meter, temperature monitor and is existed
18-25 DEG C, pH adds the helotism body through taming into bioreactor in 6-7, opens inside bioreactor
Multiple light sources, while opening Aeration fan and handling aquaculture tail water, processing time are 8-14 hours, on treated
Clear liquid enters in artificial swamp through overflow to be continued with, and the bottom of wetland variation unit is entered by the bottom of water inlet partition, successively
