Embodiment
As shown in Figure 1, a kind of circulating water culture system of efficient energy-saving, be divided into culture zone and purification of water quality district.Culture zone comprises culturing pool 1, and the water inlet of culturing pool 1 is connected with the delivery port in purification of water quality district, and the delivery port of culturing pool 1 is connected by pipeline with the water inlet in purification of water quality district.The water of culturing pool 1 and dirt enter after the purification of water quality district processes and return in culturing pool 1, so aquaculture water constantly recycles and becomes cycle water.
Culturing pool 1 is the square fillet cement pit, is of a size of 5 * 5 * 1.2m, and the water treatment zone overall dimensions is 5 * 1.2 * 1.2m, and culture zone and water treatment zone area ratio are 3: 1～5: 1, and optimum is 4: 1.At the bottom of culturing pool 1 pond, central authorities arrange four dirt sucking tubes 11, the pvc pipe that dirt sucking tube 11 is caliber 40mm by diagonal.There is sewage draining exit at the Chi Di center, and this sewage draining exit is as the delivery port of culturing pool 1 simultaneously.Dirt sucking tube 11 is communicated with sewage draining exit, for collecting the dirt in cycle water and pond.Because current can form counterclockwise whirlpool culturing pool 1 is interior, thus each dirt sucking tube 11 is met to the water inlet direction, also be the equidistant perforate of anti-water outlet direction one side.
Aquaculture wastewater flow to the purification of water quality district through outlet pipe.Purification of water quality is divided into 8 functional unit ponds, comprising the preliminary sedimentation tank 2 along water (flow) direction, second pond 3, retaining water lift pond 4, aeration filtration pond 5, suspended particulate sedimentation basin 6, filter pulp filtering ponds 7, filtration counterbalance cell 8 and water outlet cistern 9.Preliminary sedimentation tank 2, second pond 3 form elementary settling zone, and aeration filtration pond 5, suspended particulate sedimentation basin 6, filter pulp filtering ponds 7, filtration counterbalance cell 8 and water outlet cistern 9 form filtering areas.Cycle water is shown in Fig. 2 at the flow graph in purification of water quality district.
With reference to figure 1, at the in-built body elasticity filler 21 of setting up of preliminary sedimentation tank 2, in the present embodiment, be hairbrush, the aquaculture wastewater in culturing pool 1 first flows into preliminary sedimentation tank 2, and the large particulate matter in water, as residual bait chip, ight soil etc. are filtered precipitation.
Be provided with the first bolting silk net group 31 in second pond 3, be comprised of the multilayer nylon mesh tulle sheet of equidistantly arranging perpendicular to water (flow) direction, bolting silk net sheet aperture 40 orders, hang perpendicular to the water surface, and all be immersed in water.Can form the water body suspended particulate that enters second pond 3 after thereby biomembrane precipitation absorption preliminary sedimentation tank 2 is processed on bolting silk net sheet.
Water after second pond 3 is processed flows in retaining water lift pond 4, by elevator pump 41, water is evacuated to aeration filtration pond 5.
The aeration filtration pond is provided with aeration tube 51 at the bottom of 5 ponds, and these aeration tubes 51 are connected with the air inlet pipe 10 outside pond.Suspended filter material 52 also is set in pond, and microorganism can adhere on it.Water in retaining water lift pond 4 flows in aeration filtration pond 5 and decomposes the dissolubility pollutant matter such as organic matter, ammonia nitrogen, nitrite nitrogen in water body to absorb.
Be provided with the second bolting silk net group 61, the second bolting silk net groups 61 in suspended particulate sedimentation basin 6 and consist of the multilayer nylon mesh tulle sheet of equidistantly arranging perpendicular to water (flow) direction, wherein bolting silk net sheet is 60 orders.Suspended particulate sedimentation basin 6 is mainly that precipitation is adsorbed suspended particulate matter in the water body entered after aeration filtration is processed.
Sewage after suspended particulate sedimentation basin 6 is processed enters filter pulp filtering ponds 7.Filter pulp filtering ponds 7 bottom, pond pool wall ends are provided with feet, height 10cm, upper suspension layer lay-up row frame of plastic is as filter cotton frame 72, frame size is 0.5 * 0.4 * 0.4m, inside fill out cellular filter pulp, center of top position, pond arranges top water distributor 71, the pvc pipe that water distributor is the 50mm caliber, and at the pipe end, nearly filter pulp direction one side is equidistantly opened water distributing pore.Filter pulp filtering ponds 7 are mainly the dissolubility pollutant matter such as organic matter, ammonia nitrogen, nitrite nitrogen in anaerobic denitrifying adsorption-decomposition function water body.
Sewage after filter pulp filtering ponds 7 are processed enters and filters counterbalance cell 8.Filter counterbalance cell 8 pond bottom center bottom water distributor 81 is set, the pool wall end is provided with feet, height 10cm, and upper suspension layer lay-up row frame of plastic is as coral sand frame 82, and frame size is 0.5 * 0.4 * 0.4m, inside fills out thick coral sand.The effect in this pond is dissolubility pollutant matter in further anaerobic denitrifying adsorption-decomposition function water body, and coral sand discharges the materials such as calcium, adjusts pond water intermediate ion balance.
The sewage filtered after counterbalance cell 8 is processed enters water outlet cistern 9.Micropore aeration pipe 91 is installed as oxygen-increasing device, for getting rid of the gases such as Water gas, carbonic acid gas, for entering the water oxygenation of culturing pool 1 in water outlet cistern 9 bottoms.Micropore aeration pipe 91 is connected with air inlet pipe 10.
Water after oxygenation reenters culturing pool 1, and aquaculture wastewater enters preliminary sedimentation tank 2 afterwards, so constantly circulation.
At the bottom of each unit cells pond in formation purification of water quality district, all to same direction, tilt, and the bottommost after tilting is provided with sewage draining exit, the blow-off pipe 12 concentrated discharge of the dirt in pond through being communicated with sewage draining exit.
Because the system in the present embodiment has adopted multiple filtrate (elastic filler, suspended filter material, bolting silk filter screen, filter pulp, coral sand etc.) combination and biological treatment (aerobic and anaerobism combination), effectively improve microbiological treatment efficiency.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
