Abstract

The invention relates to a method and a system of pool culture. The method for regulating water quality of pool complex culture comprises the following steps: the water body discharged from a fish pool (1) inflows into an ecological crab pool (3) after being treated by a biological purifying channel (2), the water body inflows into a water body purifying equipment of clay and ceramsite (4) by power after purifying treatment in the ecological crab pool (3) and finally refluxes into the fish pool (1). The system for regulating water quality of pool complex culture comprises the following steps: arraying a plurality of fish pools (1) and crab pools (3) in a way of juxtaposition with one side provided with a biological purifying channel (2) and the other side is provided with the water body purifying equipment of clay and ceramsite (4); communicating the fish pools (1), the biological purifying channel (2) and the ecological crab pool (3) subsequently through a cannula device (5), wherein, the ecological crab pool (3) is connected with the water body purifying equipment of clay and ceramsite (4) through a water pump (6), the water body purifying equipment of clay and ceramsite (4) is connected with the fish pool (1) through an inlet channel (7). The invention is the culturing method for regulating complex water quality, which has the characteristics of low cost, low energy consumption and high efficiency and conforms to the pool culturing model of ecological principle.

Description

A kind of water quality of pool complex culture regulate and control method and regulator control system
(1) technical field
The present invention relates to pond culture mode construction technology, especially a kind of method and the regulator control system thereof of water quality of pool complex culture regulation and control.
(2) background technology
Pond culture is the main mode of China's aquaculture, occupies an important position in China's aquatic products industry.But problems such as the environmental pollution that traditional pond culture exists, water resource waste, food security also become increasingly conspicuous, and these problems have seriously restricted the sustainable development of pond culture industry.
A lot of to the research of pond culture pattern both at home and abroad.In China, " Sang Ji fishery " pattern of rising at the Delta of the Pearl River before more than 400 year is the model of ecological fishery by generally acknowledging, is described as by UNESCO in 1992 " rare in this world beautiful scenery, benign cycle model ".Since the last century the eighties, the pond culture pattern of China has had development faster, the pond ecologic breeding mode of various ways occurred, as " fish-poultry-fowl pond culture pattern ", " fish-Nong pond culture pattern ", " fish-special aquatic products product pond culture pattern " or the like.These pond ecologic breeding patterns have certain ecological effect, and have improved the material transformation efficiency in the cultivating system to a certain extent, have reduced to culture and have polluted.But all there is problems such as can't quantizing and lack systematicness in these aquaculture models.
Because generality and extensive property that landlocked freshwater is cultured, people do not pay attention to reparation of pond culture environmental ecology and aquaculture model research for many years.Only be confined to forms such as oxygenation, desilting, blowdown aspect the pond culture environmental improvement, these modes can only play temporary transient regulating action, can not tackle the problem at its root.Aspect the research of water quality of pool complex culture regulation and control model, the present domestic starting stage that also is in.90 mid-terms year in generation of last century, culture the continuous outburst of disease along with sea pond, the begin one's study environment remediation problem of sea pond of people, as people such as yellow Guoqiang (2001), test with cycle water pond, many ponds cultured prawn (Fenneropenaeus chinese), each pond be the integrated culture pond be again water treating pond, regulate and control the water ecological environment on the shrimp-cultivation pool pool.Feng Minyi etc. (2006) utilize continental rise enclosure method to carry out BIOLOGICAL CONTROL cultivating pool Pollution Study, use probiotics (MP), philippine clam (Ruditapesphilippinarum), fragrant plant mentioned in ancient texts (Gracilaria tenuistip) to experimentize respectively, find to adopt the reparation of any biology that incomplete place is all arranged separately, have only the comprehensive regulate and control method of enforcement just may realize the pond environment reparation.High-order pond ecological environmental characteristic of prawn and biological modulated control techniques thereof have been studied in the thesis for the doctorate of Shen Yuchun (2003).Aspect freshwater breeding environment regulating and controlling water quality, studied the ecotope problematic feature that the fishing rice does altogether in Yang Yong (2004) thesis for the doctorate.Introduced the catharsis of high terrestrial plant in Guo Lixin (2004) Master's thesis to breeding wastewater.Dissolve into bright grade (2004) in laboratory research zero-emission aquiculture using recirculated water machinery-bacterium-grass comprehensive water treatment system.Li Gu (2005) thesis for the doctorate has been studied combined artificial wetland-pond culture ecosystem feature and function, has introduced the ecological characteristic of composite vertical current wetland-pond culture system.More than research provides good use for reference of planning for water quality of pool complex culture control technique and model study.But they possess some special knowledge and improve on a single technology, and single or two kinds of water technology simple combination are the needs handled of incompatibility aquiculture waste water.The pond culture pattern that meets ecological principle of design low cost, low power consuming, high purification efficiency, strengthen taking good care of growing dynamic and rational balance between the producer in the ecosystem, consumer, the analyst, further excavating the biological agent potentiality, is the developing direction of pond culture mode construction technology.
(3) summary of the invention
The objective of the invention is at deficiency in the background technology and pond culture characteristics, invention a kind of with to past different pond culture modular system, this system can effectively utilize water surface for aquaculture by comprehensive ways and means, improve the availability of eutrophication material, improve pond culture water quality, reduce and culture pollutant emission, realize recycling economy.
The objective of the invention is to be achieved through the following technical solutions:
