Abstract
The present invention relates to a kind of aquatic farm circulating water cultivation method, the first step, prepares water purification facilities: second step, carries out water running management: after 1) former water enters and purifies into Shui Zongqu ecological canal, entered by water pump extracting and enter pond after water branch canal, start to breed fish; 2) when pond water quality is grown fat, carry out changing water, about 10 ~ 15% waste water enter water purification ecological canal sedimentation basin, add equivalent and purify waste water; 3) enter sedimentation basin waste water by entering clarifier-tank after precipitation, after clarifier-tank is detained 7 ~ 10 days, reach breeding water standard, open check gate, the water after purification enters into Shui Zongqu, as breeding water; ) and so forth, reach cultivation wastewater purification, recycle; Only supplement because evaporation waits the water yield of losing in whole breeding process, outwardly do not discharge breeding wastewater.Construction method of the present invention is simple, and regular maintenance is simple, with low cost, is easy to apply.
Description
Technical field
The present invention relates to a kind of aquatic farm circulating water cultivation method, belong to technical field of aquaculture.
Background technology
1) pond culture at present generally adopts " high investment, high production " aquaculture model, is characterized in; Put fingerling in a suitable place to breed by high density and drop into feed in a large number, obtaining high yield.
2) there are some researches show, the nitrogen in the feed of input, what absorbed by fish is about 49%, in the water that the nitrogen of 51% is trapped in pond by different modes and bed mud.The existence of a large amount of nitrogen, phosphorus causes body eutrophication, destroys water quality, affect fish growth, cause the generation of fish disease, and then in a large number medication, causes environmental pollution and Product quality and safety problem.
3) most plant of China build in last century the eighties to the nineties, irrigation and drainage system is unsound, and most plant is that draining and water inlet irrigation canals and ditches share in total canal one-level.Breeding wastewater discharges two approach: one is directly be disposed to the water system of adjoining with plant, produces pollute environment; Two is be disposed to plant's internal trenches system, produces pollute breeding water.
4) some plants pollute to solve breeding wastewater, build artificial swamp pollution abatement, calculate, build flat flow artificial swamp according to 100 mu of water surfaces for aquaculture, need the soil mating cultured area 20% ~ 25%, the balance of funding 100,000 yuan; Build underflow type artificial wet land, then need to mate 10 mu, soil, construction cost about 20 ~ 300,000 yuan.
The shortcoming of prior art:
1) do not build artificial swamp, breeding wastewater discharges two approach: one is directly be disposed to the water system of adjoining with plant, produces pollute environment; Two is be disposed to plant's internal trenches system, produces pollute breeding water.
2) build artificial swamp, need to take valuable land resources.Current plant land utilization rate is higher, there is no idle land, and most pond is contracted, builds artificial swamp land used and is difficult to solve.
3) build artificial swamp and need substantial contribution.
Summary of the invention
The present invention is a kind of circulating water cultivation administrative skill recycled after ecological canal purified treatment breeding wastewater.Its main contents are as follows:
1 water purification facilities
1) at cultivating pool, biological float valve is set according to 7.5% of pond area.
2) original escape canal is transform as cultivation wastewater purification ecological canal.
3) total canal of originally intaking is transform as purificating raw water ecological canal.
4) between branch canal and total canal, build check gate, the water body controlled between irrigation canals and ditches exchanges.
2 water running management
1), after former water enters and purifies into Shui Zongqu ecological canal, entered by water pump extracting and enter pond after water branch canal, start to breed fish.
2) when pond water quality is grown fat, carry out changing water (about 10 ~ 15%) waste water and enter water purification ecological canal sedimentation basin, add equivalent and purify waste water.
3) enter sedimentation basin waste water by entering clarifier-tank after precipitation, after clarifier-tank is detained 7d ~ 10d, reach breeding water standard, open check gate, the water after purification enters into Shui Zongqu, as breeding water.
4) and so forth, reach cultivation wastewater purification, recycle.Only supplement because evaporation waits the water yield of losing in whole breeding process, outwardly do not discharge breeding wastewater.
Advantage of the present invention is as follows:
1, by original culvert system transformation and operational management, reaches cultivation wastewater purification effect.
2 only supplement because evaporation waits the water yield of losing in whole breeding process, outwardly do not discharge breeding wastewater, reach breeding wastewater and recycle.
3 by original for plant enter escape canal transformation form the ecological canal of the purification of breeding wastewater, without the need to increasing soil, Economization on land, economizes on the use of funds.
4 construction methods of the present invention are simple, and regular maintenance is simple, with low cost, is easy to apply.
Embodiment
Hereinafter, will describe the present invention more fully now, show various embodiment.But the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, provide these embodiments to make the disclosure will be thoroughly with completely, and scope of the present invention is conveyed to those skilled in the art fully.
This technology is a kind of circulating water cultivation administrative skill recycled after ecological canal purified treatment breeding wastewater.Its main contents are as follows:
1 water purification facilities
1) at cultivating pool, biological float valve is set according to 7.5% of pond area.
2) original escape canal is transform as cultivation wastewater purification ecological canal.
3) total canal of originally intaking is transform as purificating raw water ecological canal.
4) between branch canal and total canal, build check gate, the water body controlled between irrigation canals and ditches exchanges.
2 water running management
1), after former water enters and purifies into Shui Zongqu ecological canal, entered by water pump extracting and enter pond after water branch canal, start to breed fish.
2) when pond water quality is grown fat, carry out changing water (about 10 ~ 15%) waste water and enter water purification ecological canal sedimentation basin, add equivalent and purify waste water.
3) enter sedimentation basin waste water by entering clarifier-tank after precipitation, after clarifier-tank is detained 7d ~ 10d, reach breeding water standard, open check gate, the water after purification enters into Shui Zongqu, as breeding water.
4) and so forth, reach cultivation wastewater purification, recycle.Only supplement because evaporation waits the water yield of losing in whole breeding process, outwardly do not discharge breeding wastewater.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable change and change.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
