Abstract

The utility model aims at arranging a supported glass greenhouse or a plastic tunnel on the south surface of the greenhouse for aquaculture, wherein a water purifying basin is arranged in the greenhouse, and aquaculture waste water discharged is used as a nutrient source to plant aquatic plant with strong water purifying capability, such as hyacinth in the water purifying basin; in a closed environment, the aquatic plant purified the aquaculture water used for circulation. Besides, an ampullaria gigas cultivation basin is also arranged in the greenhouse, the hyacinth is used for feeding the ampullaria gigas used as feedstuff for fishes, trionychids, etc. A fan is arranged on the rear wall of the supported greenhouse, air between the greenhouse for the aquaculture and the supported water purifying glass greenhouse is exchanged by the fan; therefore, hot air in the supported water purifying glass greenhouse is injected into the greenhouse for aquaculture, and the purpose of exchanging O<2> and CO<2> is realized.

Description

Band supported type greenhouse aquiculture waste water purifies and EGR

The utility model relates to the survive the winter biological cleaning of breeding wastewater of batch production aquatic products (fish, soft-shelled turtle, shrimp etc.) insulation and recycles and a moving plant nutrition source EGR.

To support soft-shelled turtle is example; culture in the greenhouse fast in batch production; 28～30 ℃ of temperature of cultivation; remaining bait of soft-shelled turtle and excreta are deposited on very fast corruption in the water in the water body; cause water pollution; have a strong impact on growth and the survival of soft-shelled turtle; for addressing this problem; the common practice is often to change water to improve water quality; warm waste water is discharged, inject after extraneous cold water is heated, frequently change water; cause the consumption of heat and water very big, so to improve water quality also be the key factor that the cost of supporting fast soft-shelled turtle increases of heating to change the water method in the winter time.Existing biological rotating disk purifies not install with the fish and vegetable symbiotic system all can not realize nutraceutical recycling.

The purpose of this utility model is that a kind of decontamination cycle device will be provided, can be in thermal environment, and be nutrient source with the breeding wastewater of discharging, planting aquatic plants.

The purpose of this utility model is to realize like this, in the south in aquaculture greenhouse supported type glass greenhouse or plastic tunnel are set, water purifying tank is set in the greenhouse, the strong aquatic organisms of water purification ability such as plantation weter hyacinth or water lettuce in water purifying tank, be provided with simultaneously Pomacea canaliculata in addition and culture the pond, feed with weter hyacinth and to raise Pomacea canaliculata, Pomacea canaliculata is re-used as the feed of aquatic animals such as soft-shelled turtle.On the rear wall that relies on the greenhouse, fan is set, relies on fan to make the air exchange of culturing between greenhouse and the supported type water purification greenhouse, both made hot-air injection breed greenhouse in the supported type greenhouse, reach O again ₂With CO ₂The purpose that exchanges.

This device is cultured pond (3), weter hyacinth breed pond (4), sandstone filter tank (6) and water purification storage pool (11) five parts by aquatic plant cultivation pond (1), Pomacea canaliculata and is formed, it is characterized in that: above-mentioned five parts link to each other with partition wall respectively, have the flowing hole (5) of a band wire netting on the partition wall, water plants plant cultivation pond is communicated with by baffle plate (2) and separates, the sandstone filter tank is by adding fine sand layer (8) in the two-layer cobble (7), have the flowing hole (10) of a plurality of areas on the partition wall in filter tank (9), also have ventilating fan (12) on the rear wall of water temperature chamber less than cobble.

The utlity model has following advantage:

Water plants absorbs the required nutritive element of growth, in the environment of sealing, purify breed water simultaneously, made water circulation use no longer outwards discharging, reduced the consumption of fuel and water, simultaneously water plants can feed again and raise Pomacea canaliculata, and Pomacea canaliculata is the high-quality protein feed of aquatic animal such as soft-shelled turtle.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the water purifying tank in the basis supported type greenhouse that the utility model proposes and the profile of air AC system;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the A-A cutaway view of Fig. 2.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

The biological water purifying tank of this device is divided into five component parts, and first is aquatic plant cultivation pond (1), is communicated with plate washer (2) and separates, and to increase the mobile distance of waste water, improves purifying water effect.Second portion is that Pomacea canaliculata is cultured the weter hyacinth of fishing for first with instrument in pond (3) and fed and raise Pomacea canaliculata, the pieces of an egg of Pomacea canaliculata take out hatching separately and give birth, the 3rd partly still cultures pond (4) for weter hyacinth purifies the Pomacea canaliculata breeding water body once more, first, two, three parts link to each other with partition wall respectively, have the flowing hole (5) of a band wire netting on the partition wall, the 4th part is sandstone filter tank (6), the sandstone filter tank is made up of folder fine sand layer (8) in the two-layer cobble (7), have the flowing hole (10) of a plurality of areas on the partition wall in filter tank (9) less than cobble, water body is after the filtering of sandstone filter tank, deposit the water purification storage pool (11) of the 5th part in, inject the heated pool that adds in aquaculture greenhouse when needing with water pump extraction and cleaning water, after the water temperature that reaches required of heating, can inject aquaculture ponds such as soft-shelled turtle.Biological water purifying tank is looked production scale and can be made by timber, plastic plate or cement.

Two-way ventilating fan (12) is installed in the wall top after relying on the greenhouse, sunny, when temperature raises in the supported type greenhouse hot-air in the supported type greenhouse is pumped into the aquaculture greenhouse.
