Abstract
The invention discloses a method and device for carrying out surface blowdown, blue-green alga treatment and oxygenation simultaneously. A drainage pipe is vertically arranged at the blowdown position in the center of a pond, a perforated blowdown pipe which is transversely connected to an elbow at the upper end of the drainage pipe and rotates around the center drainage pipe is used for carrying out surface blowdown and discharging blue-green algae at the same time, and a rotary aerator connected to the tail end of the blowdown pipe carries out oxygenation at the same time. Due to the fact that the drainage vertical pipe is fixed to the center of the pond, holes are formed in the transverse pipe, and one half of the drainage vertical pipe is immersed in surface-layer water, after the outer blowdown pipe is pulled out, only water on the surface flows in through the pipe holes; due to the fact that the transverse pipe rotates, all surface dirt is sucked into the pipe to be discharged. Due to the fact the blue-green algae generally exist on the surface layer of the water, the blue-green algae are sucked and discharged while the surface dirt is sucked and discharged, and the blue-green algae are treated. Due to the fact that the aerator is unfixed, the blue-green algae are started to push the pipe to rotate around the center pipe along the water surface, and the rotary aerator and the driven pipe can stir the surface water to achieve the aim of oxygenation.
Description
Technical field
The present invention relates to aquaculture field, particularly relate to the method for cultivating pool surface blow-off with improvement blue-green algae, oxygenation simultaneously and device.
Background technology
In aquaculture process, cultivating pool water surface often has the foreign material such as dead algae to swim in the water surface, and one is affect the molten oxygen of air to enter water body, and two is easily eaten by mistake and cause poisoning by aquaculture kinds such as fishes and shrimps. Cultivation settling decomposes consumption oxygen at the bottom of pond, release hazardous and noxious substances, and polluted-water, causes fish disease to take place frequently, and feed conversion rate is low, and aquaculture cost increases, and cultivation settling has exceeded water body self-purification ability, causes eutrophication, causes aquaculture water contaminating endogenous. At present, popularity pond, whole nation bottom blowdown method, pond is transformed into central blow-down pond, adopts pan bottom shape structure, establish a sewage draining exit in pond central authorities exactly, by burying pvc pipe at the bottom of the pool underground outside pond, blowdown place outside pond is vertical a pvc pipe, higher than the pond water surface, can be used as detection pond water level, pulling out standpipe when blowdown, water is due to hydraulic pressure effect just discharge. This kind of blowdown mode is called bottom blow-down, can effectively improve cultivation water, it is to increase pond fish quality and yield, but because the water of bottom and dirt can only be discharged, the dirt on surface, pond also exists, and blue-green algae also exists, and still easily causes pond waters anoxic at night.
Blue-green alga bloom is the result of the continuous eutrophication of water body in recent years, in natural lake, river and water used for aquiculture, harmful algal blooms has become seriously affects quality of water environment and the global problem of water ecology safety, and the development rapidly of industrial or agricultural accelerates the discharge of eutrophy salt and the eutrophication of water body such as nitrogen phosphorus, it also seriously affects the development of culture fishery simultaneously. Removal algal bloom has been carried out a large amount of experiments and research work by people in recent decades, generally adopts physics method, chemical method, changes water law except the methods such as algae, biological treatment, combination process method and animal predation are administered. ?ut lame waterside zinc stewing figurines in ? С ? small house border are whistled, the tranquil interpolation scratching promise ? chemical agent of С ? can bring new pollution to water body again. Chemical method institute with medicament has multiple, and such as copper sulfate, this pharmacy effect is of short duration, and it itself is also a kind of pollutent, should not repeatedly use. Change water law to cure the symptoms, not the disease. Biological method utilizes the growth of the natural enemy of algae and the amicine confrontation algae of generation thereof, breeding to suppress. This kind of biology is wanted efficiently can to remove Microcystis aeruginosa fast and can be guaranteed again the harm that aquaculture water and other water bodys can not cause species to invade, and the biological community structure and the eubiosis to water body itself can not produce to threaten, can be used for removing on algae bacterial classification preparation market of production application at present little, great majority only can stop at laboratory stage. Biological method is the molten algae of microorganism especially, and its onset time is very slow, and long action time, uses during actual aquaculture production is put into practice and has certain difficulty. Physical method is utilized to remove algae such as by the method for container mechanical harvest algae, it is difficult to be applied to the removing (consuming time, consumption money) that water body in large pollutes. Flocculent precipitation is the effect enrichment algae by sorbent material and algae or the molecular attraction between algae and pollutent, thus a kind of method that algae is removed from water body. But flocculant dosage ready-made at present is all very big. If adding the effect that low dose is difficult to reach desirable. Although having many methods administered by blue-green algae at present, but each method has respective relative merits, can not get widespread use. And blue-green algae is a kind of algae generally existed, be mainly distributed in surface layer of water, absorb sunlight and breed rapidly, it is easy to cause night pond waters anoxic and cause breed variety dead.
Summary of the invention
The present invention can be realized getting rid of surface contaminants by one method and device simultaneously, gets rid of blue-green algae and carries out oxygenation three kinds of objects in the middle of pond.
The technical scheme that the present invention gets is:
A kind of surface blow-off and the method administering blue-green algae, oxygenation simultaneously, it is characterized in that: at cultivation Chi Zhongyangpaiwuchu, water shoot is vertically set, perforate blow-off pipe by water shoot upper end bend pipe lateral connection, around central authorities' water shoot rotation sweeps away the water surface and carries out surface blow-off, siphon away dirt and blue-green algae, the rotation oxygenating machine that blow-off pipe end connects oxygenation simultaneously.
The device of a kind of surface blow-off and improvement blue-green algae oxygenation simultaneously, it is characterized in that: at cultivation Chi Zhongyangpaiwuchu, water shoot insertion water port is vertically set, water shoot upper end connects 90 degree of bend pipes by bearing, bend pipe is the unidirectional perforate blow-off pipe of lateral connection one section again, and the end at blow-off pipe connects an oxygenating machine bubbled through the water column by joint.
The length of described blow-off pipe regulates according to cultivating pool radius, and the half of pipe there is not upstream face, and sense of rotation side has row's circular hole.
Described oxygenating machine is not fixed.
The invention has the beneficial effects as follows:
The present invention is owing to being fixed with a standpipe and waterproof in cultivating pool central authorities, transverse tube has hole, and half is immersed in surface water, so after extracting the blow-off pipe of outside, only the water on surface is flowed into by the hole on transverse tube, add transverse tube in rotation, just discharge in whole for the dirt on surface tail pipe. And generally concentrate on the top layer of water due to blue-green algae, traditional bottom blow-down cannot discharge surface water, also blue-green algae just cannot really be administered, pharmaceutical chemicals of splashing easily affects again fishes and shrimps growth, the present invention can be single-minded discharge surface water and foreign material, also while suction goes out surface contaminants, just discharge blue-green algae, administer blue-green algae.In addition, the oxygenating machine of the present invention is not fixed, and starts oxygenating machine and namely promotes transverse tube to rotate around central canal along the water surface, and the oxygenating machine of rotation and the transverse tube of drive stir the object that surface water just can reach oxygenation.
