The drainpipe being equipped with is connected to rotary drum Microfilter, just by separation solid state fish, by discharge into water to first class purification area, the fish of discharge
Just discharge value adds flocculant into settling tank and promotes excrement sedimentation to settling tank.
The beneficial effects of the present invention are: subregion cultivating system of the invention forms a kind of water circulation, richness can be sought
The water of feedingization is changed into the water that suitable water supports biological existence, while also using the nutriment in the water of eutrophication as vegetable fertilizer
Material, has achieved the purpose that turn waste into wealth, has reduced the waste of water resource, advantageously reduce cost.This circulatory system need to only make
With a suction pump, operating cost has been saved.
Detailed description of the invention
Fig. 1 is subregion cultivating system structural framing figure of the invention.
Specific embodiment
To make the purpose of the present invention, technical solution and effect clearer, clear and definite, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that specific examples are only used to explain the present invention for description described herein, and do not have to
It is of the invention in limiting.
The present invention provides a kind of subregion cultivating systems, as shown in Figure 1, subregion cultivating system of the present invention includes being sequentially connected
Culture zone and purifying area, the culture zone bottom be higher than the water surface of purifying area, and two regions are relatively independent, and the water of culture zone passes through
Discharge outlet and discharge of pipes to purifying area purify, and due to already existing difference in height, drainage procedure is assisted without equipment such as water pumps,
The purified water of purifying area is pumped into culture zone by pulsating pump, so constitutes a circulation.
Wherein purifying area selects natural water, such as pool to have mud, nearest rich in the water after nature bacterium colony system purification
Nature, while purifying area is at least divided into two regions, first class purification area, secondary purification.
First class purification area is for adjusting ammonia-nitrogen content, since the sewage of culture zone is directly discharged to first class purification area,
The ammonia-nitrogen content in the region is higher, its content need to be reduced by chemically or physically method, and general chemical method uses breakpoint chlorination
Method, to the removal rate of ammonia nitrogen up to 90~100%, treatment effect is stablized, and not by Water Temperature, capital cost is not also high, but it is transported
Row is costly, and residual chlorine and chlorinatedorganic must be post-processed.Physical method selects zeolite, denitrogenates work using the absorption of zeolite
With in the three-D space structure of zeolite, having well-regulated cellular structure and hole, make it have sieve effect, exchange adsorption
The excellent performances such as selectivity, thermal stability and shape stability.There are many type of natural zeolite, for removing the predominantly oblique of ammonia nitrogen
Ptilolite.
First class purification area carry out preliminary purification after, water body due to first class purification area horizontal plane be higher than secondary purification area,
So that water body forms drop when reaching secondary purification area from first class purification area, cyanobacteria in the pre- waterproof body of the shearing force of drop is utilized
It generates, meanwhile, it is provided with baffler or divider wall between purifying area not at the same level, for subregion and forms drop phenomenon.
In order to preferably ensure clean-up effect, purification can be divided into three and area above, both ends are respectively first
Purifying area and self-purification area, centre are one or several regulatory regions, and the effect of the regulatory region is to manufacture nothing by addition yeast
Oxygen environment, so that the breeding of denitrifying bacteria be promoted to react, the final ammonia nitrogen consumed in water body, it is at different levels between have water-head,
And drop is formed, guarantee the generation of shearing force.
Natural evolution area weakens the catharsis of chemical addition agent, and the main natural ecosystems by water body carry out
Metabolism regulation reaches final evolution effect, and pulsating pump is located at the end in self-purification area, far from drop.
Culture zone, which can be designed as forms, the bottom such as box cultivation or the cultivation of other ponds, can form a gradient
10 ° of wedged bottom is discharged convenient for the deposition of excrement by drainpipe.
Pulsating pump is downdraft, only draws the superficial water in self-purification area, guarantees the high quality at the original water source in culture zone, high
Oxygen content etc..
The solid-liquid separating machine for separating particulate excrement is additionally provided on the pipeline of culture zone draining, which can be selected
Rotary drum Microfilter, it is molten as reduced the load of purifying area to water body that this micro-filtration technique reduces excrement ammonia nitrogen.
The excrement water of Microfilter discharge is stored in settling tank and carries out feces deposition, while can launch flocculant inward and accelerate excrement
Just sedimentation.Excrement after sedimentation is fished out to fermentation vat, progress anaerobic fermentation-is decomposed, forms organic fertilizer.
Embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but can not
Therefore it is construed as limiting the scope of the patent.It should be pointed out that for those of ordinary skill in the art,
Under the premise of not departing from present inventive concept, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.
Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
