Technical background
Along with the aggravation of water pollution and the decline of fishing resources, industrial circulating water cultivating has become the main developing direction of present culture fishery.The key of industrial circulating water cultivating is water technology, and biologic treating technique has crucial effects in the industrialized culture water treatment.China's industrial circulating water cultivating is from external introduction with the biofilter major part or adopts industrial sewage to handle and use biofilter at present.Have not yet to see rotary type efficient biofiltration device successful Application in industrial circulating water cultivating is produced.
Summary of the invention
The purpose of this invention is to provide a kind of rotary type efficient biological filtering water treatment equipment for circulating water cultivation, it can remedy the above-mentioned deficiency of prior art.
A kind of rotary type efficient biological filtering water treatment equipment for circulating water cultivation, it is characterized in that having a water pump, the outlet of this water pump communicates with the inlet of ejector by pipeline, the outlet of ejector is communicated with the inlet of pressure stabilizing cavity by pipeline, the outlet of pressure stabilizing cavity communicates with the rotation chamber by the rotation water channel, the indoor bottom of rotating drum is provided with current rotation boss, the rotation water channel is opened on the wall of rotation chamber bottom, have a water outlet on the upper portion side wall of rotation chamber, water outlet is outer to have an annular settling chamber and a foam collecting chamber around the rotation chamber, between annular settling chamber and the foam collecting chamber toroidal membrane is arranged, annular settling chamber and foam collecting chamber are by the top UNICOM of toroidal membrane; There is a perforate to communicate with clean water basin on the toroidal membrane by pipeline.Settling chamber and foam collecting chamber bottom communicate with sewage lagoon by pipeline and valve respectively.
The present invention can greatly improve dissolved oxygen in water, and the filtrate of high speed rotating has increased specific surface area and produced stable microbial film simultaneously, and water quality is effectively purified, and can improve the water treatment effect greatly.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Rotary type efficient biological filtering water treatment equipment for circulating water cultivation of the present invention has a water pump 1, the outlet of water pump 1 communicates by the import of pipeline with ejector 2, the negative pressure that produces by ejector 2 sucks air, and forms water containing high dissolved oxygen with the water thorough mixing that enters wherein.The outlet of ejector 2 is communicated with by the inlet of pipeline with pressure stabilizing cavity 3, and the outlet of pressure stabilizing cavity 3 communicates with rotation chamber 6 by rotation water channel 4, and rotating channel 4 is opened on the wall of rotation chamber 6, and the bottom in the rotation chamber 6 is provided with current rotation boss 5.After above-mentioned water containing high dissolved oxygen stream enters rotation chamber 6 through rotating channel 4, under the effect of current rotation boss 5, produce the rotation upwelling, make water containing high dissolved oxygen and the filtrate thorough mixing that is placed in the rotation chamber 6, and the rotation that suspends is risen, the filtrate that suspends has high specific surface area, and the microbial film that adheres on this filtrate plays cleaning action to water quality.Upper portion side wall at rotation chamber 6 has a water outlet 7, around rotation chamber 6 an annular settling chamber 8 and a foam collecting chamber 9 is arranged outside the water outlet 7, and a toroidal membrane 10 is arranged between annular settling chamber 8 and the foam collecting chamber 9, and passes through the top UNICOM of toroidal membrane 10.One perforate is arranged on the toroidal membrane 10, and communicate with clean water basin 14, the clear water after filtering can be introduced clean water basin 14 by pipeline.Settling chamber 8 and foam collecting chamber 9 bottoms communicate with sewage lagoon 13 by pipeline respectively, stopping valve 11 and 12 are housed respectively on the pipeline, open stopping valve 11 impurity in the energy settling chamber 8 is introduced sewage lagoon 13, open stopping valve 12 and the foam in the foam collecting chamber 9 can be introduced sewage lagoon 13.
The invention provides a kind of rotary type efficient biological filtering water treatment equipment for circulating water cultivation, during use, suck air when the water that the water pump 1 of this device is made passes through jet pipe 2 and produce high-solubility oxygen water with the water thorough mixing, current enter pressure stabilizing cavity 3 by pipeline, water in the pressure stabilizing cavity 3 enters rotation chamber 6 through rotation water channel 4, current rotation boss 5 is set in the rotation chamber 6, and be placed with the granular biological filtrate, high-pressure rotary current drive biologic packing material rotates together and rises, the specific surface area of filtrate is increased, and under the high-solubility oxygen situation, form microbial film, water quality is purified, the high speed rotating of filtrate makes the microbial film on the filtrate keep homogeneous thickness simultaneously, difficult drop-off has greatly improved the water treatment effect, in the current high speed rotating, the air that is dissolved in the water overflows the formation bubble from water, make impurity enter settling chamber 8 and foam collecting chamber 9 by exporting 7.The water that purifies enters the annular settling chamber 8 that rotates outside the chamber 6 by water outlet 7, enters clean water basin 14 through sedimentary water by the road by the perforate on the toroidal membrane 10.The foam that produces enters foam collecting chamber 9 through the top of toroidal membrane 10, opens stopping valve 11, the impurity in the settling chamber 8 can be introduced sewage lagoon 13, and the foam of opening in the stopping valve 12 foam collecting chambers is introduced sewage lagoon 13.
