The cultivating system of industrialization stratified pumping clear water circulation

Technical field

The utility model relates to a kind of aquatic products industrialization circulating water culture system, particularly a kind of cultivating system of industrialization stratified pumping.

Background technology

Circulating water cultivation is the highest mode of production of industrial technology application level in the fish production, have production efficiency high, economize on water, save 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; 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 Sustainability and develops fast.

At present, approximately 8,000,000 square metres of domestic industrial aquaculture areas, wherein circulating water cultivation only has 400,000 square metres, and all the other mostly are flowing water culture.The flowing water culture mode is when having wasted a large amount of water resources, and the unordered discharging of breeding wastewater has caused great environmental pollution, so flowing water culture 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 the problems such as technology very complicated, cost of investment are larger, have restricted to a certain extent the fast development of circulating water cultivation.

The at present technological process of industrialization circulating water culture system mainly is:------------culturing pool is returned in biofiltration (biofilter, biofilter etc.)---water quality optimizing (sterilization, temperature adjustment, oxygenation etc.)---to physical filtering (equipment such as Microfilter, sieve bend, filtering tank) to culturing pool in air supporting in the pump pond.Wherein the Main Function of physical filtering part is with the residual bait in the aquaculture 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 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.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of cultivating system of industrialization stratified pumping clear water circulation, can utilize the at the middle and upper levels water of culturing pool to circulate to reach, simplification of flowsheet, the purpose of saving equipment investment and equipment operation energy consumption.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of cultivating system of industrialization stratified pumping clear water circulation, comprise culturing pool, buffering regulating reservoir, flotation tank, the biological purifying tank 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 culturing pool by water inlet pipe, forms circulating water culture system; But described culturing pool 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 of described culturing pool.

Preferably, the middle and upper part of described drainpipe has several perps or circular hole.

Pass through technique scheme, the drainpipe that the cultivating system of the industrialization stratified pumping clear water circulation that the utility model provides 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 the gentle regulating reservoir that rushes of total water return pipeline, then with water circulating pump it is pumped in the flotation tank, by lighter suspension in the pneumatically supported mode Separation of Water, mucus and colloid albumen, then flow into biological purifying tank, pass through nitration reaction, ammonia nitrogen, nitrite, the harmful substances such as hydrogen sulphide can effectively be removed minimizing, flow into again the water quality optimizing pond, 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 in the culturing pool by water inlet pipe at last, form totally enclosed circulating water culture system.

Simultaneously, for remaining in the organic particulate matters such as residual bait in the culturing pool, ight soil, by the vortex water flow in the culturing pool, 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, organic granular foreign material in the culturing pool are rejected to outside the system.This technical scheme has been omitted the equipment of physical filtering link, has simplified original Process of Water Circulating System flow process, has saved the energy consumption of equipment investment and equipment operation, has improved comprehensive benefit, therefore has broad application prospects.
