Description
Technical field
The present invention relates to a kind of aquatic products industrialization circulating water culture system and method for treating water, particularly a kind of cultivating system of industrialization stratified pumping and method.
Background technology
Circulating water cultivation is the highest mode of production of industrial technology application level in the fish production, has the production efficiency height, economizes on water, saves land, the characteristics of energy-saving and emission-reduction.Industrialization is the inexorable trend of Modern Fishery development; its promote to form low consumption, capable of circulation, low emission, the continuable industrial structure and operational mode; be that China's mariculture industry is by the only way of extensive aquaculture model to the transformation of modernization industryization aquaculture model; it is not only significant to effective utilization and the ecological protection of water resource; main is effectively to change the fish production mode, promotes blue economic sustainable development fast.
At present, about 8,000,000 square metres of domestic industrial aquaculture area, wherein circulating water cultivation only has 400,000 square metres, and all the other mostly are flowing water and culture.The flowing water breeding way is when having wasted great amount of water resources, and the unordered discharging of breeding wastewater has caused great environmental pollution, so flowing water breed urgent need upgrading, and the circulating water cultivation development space is huge.But at present the circulation water breeding technique of China and institution all exist problems such as technology very complicated, cost of investment are bigger, have restricted the fast development of circulating water cultivation to a certain extent.
The technological process of industrialization circulating water culture system at present mainly is: culture the pond, and------physical filtering (equipment such as Microfilter, sieve bend, filtering tank)------return and culture the pond in air supporting by biofiltration (biofilter, biofilter etc.)---water quality optimizing (sterilization, temperature adjustment, oxygenation etc.)---in the pump pond.Wherein the main effect of physical filtering part is with the residual bait in the breed water and the organic particulate matter Separation of Solid and Liquid such as ight soil of fish, be rejected to outside the circulatory system, alleviate the load of follow-up biological cleaning with this, but in this link, also exist a lot of problems, as the cost of filtering plant equipment is relatively more expensive, fault rate is than higher, and seawater exists the operation of burn into equipment to need to consume many problems such as electric energy to the device fabrication material.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of cultivating system and method for industrialization stratified pumping clear water circulation, can utilize the water at the middle and upper levels of culturing the pond to circulate to reach, simplify technological process, save the purpose of equipment investment and equipment operation energy consumption.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of cultivating system of industrialization stratified pumping clear water circulation, comprise breed pond, buffering regulating reservoir, flotation tank, the biological cleaning pond that links to each other successively and the water quality optimizing pond of water body being carried out sterilization, oxygenation, temperature adjustment, final described water quality optimizing pond links to each other with described breed pond by water inlet pipe, forms circulating water culture system; But described breed pond central authorities vertically are provided with the drainpipe of stratified pumping, and described drainpipe links to each other with described buffering regulating reservoir by total water return pipeline, and central authorities are provided with particle and compile ejector at the bottom of the pond in described breed pond.
Preferably, the middle and upper part of described drainpipe has several perps or circular hole.
A kind of cultural method of industrialization stratified pumping clear water circulation, by culturing perps or the circular hole of the drainpipe middle and upper part that pond central authorities vertically set up, choose the water at the middle and upper levels of culturing the pond, flow into described buffering regulating reservoir by pipeline, enter flotation tank, biological cleaning pond and water quality optimizing pond more successively, return again at last and culture the pond, form circulating water culture system.
Preferably, residual bait in the described breed pond in the lower layer of water, ight soil the like waste, be pooled to through the cyclonic separation effect of culturing the pond that the particle of central authorities compiles in the ejector at the bottom of the pond, regularly open and be located at the by-pass valve control that the particle of culturing outside the pond compiles ejector, discarded object is rejected to outside the recirculation system.
Pass through technique scheme, the drainpipe that the cultivating system of industrialization stratified pumping clear water circulation provided by the invention utilizes the middle and upper part to have perps or circular hole is chosen clear water at the middle and upper levels, its gravity flow is imported total water return pipeline eases up towards regulating reservoir, with water circulating pump it is pumped in the flotation tank then, by pneumatically supported mode divide dried up in lighter suspension, mucus and colloid albumen, flow into the biological cleaning pond then, pass through nitration reaction, ammonia nitrogen, nitrite, harmful substances such as hydrogen sulphide can effectively be removed minimizing, flow into the water quality optimizing pond again, carry out ultraviolet-sterilization, oxygenation, temperature adjustment etc., total gas level in the water and water quality are approached or be better than fresh nature seawater, be back to by water inlet pipe at last and culture in the pond, form totally enclosed circulating water culture system.
Simultaneously, for remaining in organic particulate matters such as the residual bait of culturing in the pond, ight soil, by culturing the vortex water flow in the pond, there is the particle of autonomous channel to compile in the ejector at the bottom of being pooled to the pond, regularly open the by-pass valve control that particle at the bottom of the pond compiles ejector every day, will culture that the organic granular foreign material are rejected to outside the system in the pond.This technical scheme has been omitted the equipment of physical filtering link, has simplified original circulation technological process, has saved the energy consumption of equipment investment and equipment operation, has improved comprehensive benefit, therefore has broad application prospects.
