Description

A kind of efficient circulation cultivating system

Technical field

The utility model relates to a kind of efficient circulation cultivating system, belongs to cultural technique field.

Background technology

Circulating water cultivation is the highest mode of production of industrial technology application level in fish production, have production efficiency high, economize on water, save land, the feature 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; it is the only way that China's mariculture industry is changed to modernization industryization aquaculture model by extensive aquaculture model; it is not only significant to effective utilization and the ecological protection of water resource; main is effectively to change fish production mode, promotes blue Economic Sustainability and develops fast.Since reform and opening-up, the fishery development policy of " take and support as main " is carried out by China.Pond culture, the critical role with its area, output in total amount becomes the major part of China's aquaculture.In the last few years, because raiser lacks the cultivation idea of science, excessively pursue economic benefit at the moment, blindly improve cultivation density and output, cause the residual bait of a large amount of high protein feeds and fish excreta to accumulate in breeding environment, body eutrophication, water quality degenerates, this not only causes the underproduction, and even large area outburst fish disease, causes very big loss to fish production.Because traditional aquaculture mode is all open substantially, its production is extensive in addition, water resource waste, and the problems such as breeding pollution have seriously restricted the development of pond culture industry.There are some researches show, in the moist forage of throwing something and feeding in pond culture, have 5～10% by fish, not eaten; And had 25～30% with the form of ight soil, to discharge in the feed of the edible digestion of fish; The nitrogen of nature and artificial input, phosphorus are except only a part is with breed variety output, and having 50% enrichment at least is pond sediments.The fish that cultivate in this environment, after coming into the market, have also formed certain threat to the mankind's health.Thereby the pond healthy breading system of a kind of effective alleviation water environment pressure of research and extension is extremely urgent.

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.Flowing water culture mode is when having wasted a large amount of water resources, and the unordered discharge of breeding wastewater, has caused great environmental pollution, so flowing water culture urgent need upgrading, and 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 problems referred to above that exist in order to solve prior art, the utility model provides a kind of efficient circulation cultivating system.

Summary of the invention

For the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of efficient circulation cultivating system.

A kind of efficient circulation cultivating system, comprise aquaculture pond and the plant filter tank being connected successively by water pipe, biofilter, buffering regulating reservoir, flotation tank and water body is carried out to sterilization, oxygenation, the water quality optimizing pond of temperature adjustment, the water inlet in plant filter tank is connected with the discharge outlet of culturing pool, the water inlet of biofilter is connected with the discharge outlet in plant filter tank, water quality optimizing pond is connected with described culturing pool by water inlet pipe, form modular cycle water pond breeding ecological device, described culturing pool central authorities are vertically provided with drainpipe that can stratified pumping, described drainpipe is connected with described buffering regulating reservoir by total water return pipeline, at the bottom of the pond of described culturing pool, central authorities are provided with particle and collect ejector, described cultivating pool can be divided into 2 or a plurality of series connection, each pond is east-west, 2 mu of areas, dark 2.5 meters of pond, is furnished with bottom oxygenation facility, vane type oxygenation facility and change wetting system, guarantee that water body has sufficient dissolved oxygen.This pond can be divided into cage culture district, collecting dung district and purifying area 3 parts.Between described cultivating pool, by culvert pipe, mutually connect, culvert pipe is positioned at bottom, the ridge, pond, at front one end of culvert pipe water inlet, inserts a standpipe, and riser top is set up short sleeve in order to regulate and control water level, and the middle and upper part of described drainpipe has several perps or circular hole.

Described pond healthy breading system, connects mutually by culvert pipe between described cultivating pool, and culvert pipe is positioned at bottom, the ridge, pond.At front one end of culvert pipe water inlet, insert a standpipe, riser top is set up short sleeve in order to regulate and control water level; For preventing the fry string pool, at the additional hurdle cover pot of standpipe.During operation, sleeve pipe is extracted out, so that the superficial water in previous stage pond flows into voluntarily next collection pond bottom under differential pressure action.

Described pond healthy breading system, in described plant filter tank, be provided with the plant that area coverage is filter tank area 50%, institute's Plants is the reed (Phragmites australis) of local common grass family reed genus, the India canna (Canna indica) that Cannaceae India canna belongs to, the peppermint of Labiatae Mentha.

Described pond healthy breading system, is provided with biological purification plant in described biofilter, utilizes the microbial population with catharsis, as digestion flora and denitrification flora etc., water body is purified.

Pass through technique scheme, the drainpipe that the cultivating system of the industrialization stratified pumping clear water circulation that the utility model provides utilizes middle and upper part to have perps or circular hole is chosen clear water at the middle and upper levels, flow automatically and imported the gentle regulating reservoir that rushes of total water return pipeline, then with water circulating pump, be pumped in flotation tank, by lighter suspension in 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 water quality optimizing pond, carry out ultraviolet-sterilization, oxygenation, temperature adjustment etc., total gas level in water and water quality are approached or be better than fresh nature seawater, finally by water inlet pipe, be back in culturing pool, form totally enclosed circulating water culture system.

Simultaneously, for remaining in the organic particulate matters such as residual bait in culturing pool, ight soil, by the vortex water flow in culturing pool, the particle that is pooled to Di You autonomous channel, pond collects in ejector, regularly open the by-pass valve control that particle at the bottom of pond collects ejector every day, organic granular foreign material in culturing pool are rejected to outside 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.
