Description

Micro-flocculation water pump and cultivation tail water circulation treatment system
Technical Field
The invention relates to the field of water treatment, in particular to a micro-flocculation water pump and a cultivation tail water circulation treatment system.
Background
China is a large country of aquaculture, and along with the continuous improvement of demands of people on aquatic products, the aquaculture scale of China is also continuously increased. In the aquaculture process, aquaculture tail water containing aquatic animal feces, feed, medicines and the like can be produced, and if the tail water is not properly treated, serious harm to the ecological environment can be caused. Currently, government authorities also place increasing emphasis on the regulation of aquaculture tail water. Taking Jiangsu province as an example, jiangsu province in 6 months in 2021 issues "the discharge Standard of Tail Water for Pond culture", which provides a powerful basis for strengthening the pollution control and the promotion of the ecological healthy cultivation level of aquatic products in Jiangsu province. Along with the continuous improvement of the ecological environment quality requirements of China, a more perfect supervision system is built in the future.
The current three-pond two-dam treatment mode is the most commonly used mode of the aquaculture tail water, and the patent application with the application number of CN110590061A discloses an ecological purification and circulation system suitable for the tail water of an inland freshwater aquaculture pond, and the circulation system can effectively remove solid particle impurities, dissolved nitrogen and phosphorus content in the water, can effectively degrade pollutants and harmful substances, and has the advantages of environment beautifying, less investment, low running cost and the like. However, this system also has the following drawbacks during operation:
(1) The occupied area is large. The mode of three ponds and two dams requires that the area of tail water treatment facilities accounts for more than 6 percent of the cultivation area, and the proportion of part of cultivation types is even more than 10 percent; at present, land resources are increasingly scarce, are not only basic production data of agricultural production, but also material basis for survival and development of human beings, and if the proportion of the area of a treatment facility to the cultivation area can be reduced to 8% or below, important economic benefits can be generated, and important social benefits can also be generated.
(2) The treatment efficiency is low. The mode of 'three-tank two-dam' mainly realizes the removal of pollutants through modules such as a sedimentation tank, a filtering dam, an aeration tank, an ecological purification tank and the like, the whole treatment process and the independent treatment module have no theoretical basis and actual conditions for the efficient removal of pollutants, the operation mode is from operation experience, no support of basic theory is provided, and in practice, the water quality of 'three-tank two-dam' effluent is unstable.
(3) Poor impact load resistance. When the water amount, the water quality and the water temperature are changed greatly, the treatment mode does not have a mode for coping with the impact load. In addition, in the current aquaculture, farmers usually adopt a mode of batch treatment of tail water, namely, the tail water is intensively treated when the quality of the aquaculture tail water is deteriorated or the aquaculture period is finished, and the precondition of good operation of the three-pond two-dam is that the three-pond two-dam is in an operation state all year round, so that on one hand, the mode of the three-pond two-dam is not in line with the use habit of the farmers, and on the other hand, the water quality of the effluent of the three-pond two-dam is difficult to ensure during the centralized treatment. .
(4) The process flow is more, the construction, operation and management costs are high and complex. The whole process requires structures such as a sedimentation tank, an aeration tank, an ecological tank, a filtering dam and the like, and has more processes and higher various costs.

The method is characterized by further comprising a water collecting channel, wherein tail water to be treated in the culture pond is firstly collected into the water collecting channel, and then tail water in the water collecting channel is pumped into a sedimentation tank through a micro flocculation water pump.
As an improvement, the depth of the water collecting channel is lower than the bottom of the culture pond; the water collecting channel is provided with a gradient of 1 per mill towards the micro flocculation water pump, and the deeper end of the water collecting channel is connected with the micro flocculation water pump through a water pump inlet pipe of the micro flocculation water pump.
As improvement, porous adsorption particles are arranged in the filter dam, the porous adsorption particles are anthracite, volcanic rock, ceramic particles or coral stone, and the particle sizes of the porous adsorption particles are sequentially reduced along the advancing direction of water flow.
As an improvement, a disinfection ultraviolet lamp is arranged on the water surface of the disinfection tank.

Compared with the prior art, the invention has the beneficial effects that:

Therefore, the treatment efficiency of the invention is obviously improved compared with a three-pool two-dam treatment method. In addition, as the treatment of the sedimentation tank and the filtering dam is improved, the load of the subsequent treatment is also obviously reduced.
(2) The impact load resistance is strong.

Detailed Description
The present invention will be described in further detail with reference to examples.
(1) From the recycling treatment and utilization angle of the cultivation tail water, the water pump is required to be arranged, otherwise, the tail water cannot acquire the lifting water head, and recycling cannot be realized. The invention skillfully utilizes the mixing effect of the high-speed rotating blades of the centrifugal pump, so that the centrifugal pump has the effect of improving the water head of the tail water of the cultivation, simultaneously achieves the aim of quickly mixing the pollutants with the coagulant to remove the stability of the pollutants, and develops the micro-flocculation water pump on the basis. The micro flocculation water pump can replace a common water pump, so that the micro flocculation effect can be realized at the water pump.
The pollutant sources of the culture tail water are mainly residual baits, feces, dead organisms and the like, and the culture tail water can be divided into suspended matters, colloid, dissolved matters and the like according to the size of the pollutants, wherein the suspended matters, the colloid and the like can be removed through coagulation. The micro flocculation process adopted by the invention can improve the removal effect of suspended matters and colloid, because the suspended matters and the coagulant in the water pump are quickly mixed and destabilized, the suspended matters and the colloid with the stability removed form micro flocs, and the precipitation efficiency can be inevitably improved according to Stokes formula due to the increase of the size of the micro flocs. In addition, as the destabilization of pollutants in the water body is realized, the filter material can better act with the pollutants according to the filtering theory, so that the filtering efficiency can be improved through the micro flocculation process. Because the pollutants can be mostly removed on the sedimentation tank and the filtering dam, the treatment load of the subsequent treatment process is obviously reduced, which lays a foundation for the efficient treatment and utilization of the culture tail water. Finally, if a coagulant with characteristic pollutant removal function, such as a coagulant with high-efficiency removal capability for phosphorus, antibiotics and heavy metals, is used in the coagulant liquid storage tank, the process system can significantly improve the removal capability for removing relevant characteristic pollutants. That is, the process of the invention fully uses the advantages of the coagulation process and improves the pollutant removal capacity.
(2) When the ecological ditch is adopted, the partition wall of the ecological ditch can promote disturbance in the water body and collision of micro floccules in the flowing process of the destabilized water body, so that larger floccules are promoted to be formed, and the average size of pollutants in the water body is further improved. As previously mentioned, this will further enhance the contaminant removal capacity.
(3) The ecological pool is divided into an aeration zone and a non-aeration zone, DO value in water from a sedimentation pool and a filter dam is reduced, and anaerobic reaction can be carried out. The back end of the ecological pool, namely the back end of the whole process is subjected to aeration treatment, and at the moment, aerobic reaction, namely ammoniation and denitrification reaction can be carried out. Through the circulation effect of the reflux pump, the cultivation tail water circulation treatment system provided by the invention can realize the effect of multistage AO serial connection, and effectively realize the denitrification effect. This has a great value for solving the eutrophication problem of the cultivation tail water. The reflux pump can be closed according to actual demands, the system can be flexibly adjusted, and the system can be applicable according to actual demands.
