In the present water treatment device, as shown in the above patent, if the water pump is disposed outside the water body, one end of the suction pipe is generally immersed below the liquid level of the water body, and the other end (directly connected to the water pump end) of the suction pipe is higher than the liquid level of the water body, so that the water body can be pumped into the water pump by the self-priming principle. Otherwise, one end of the water suction pipe is immersed below the water surface, the other end of the water suction pipe is lower than the water surface, and the pipeline forms an inverted U-shaped shape, so that air in the U-shaped pipeline can not be discharged all the time in the water suction process of the water pump, the water pump can not be sucked into the water pump, the water pump can not normally operate, equipment is in failure, and the application range is greatly limited.
However, according to the prior art, if the liquid level of the water body is high and the water pump needs to be arranged at a position higher than the liquid level of the water body, a constructor needs to transport and install the pump at the higher position by means of a ladder and other tools, which causes a lot of problems, such as inconvenient installation, increased construction risk, increased cost of an installation platform, too high center of gravity, easy dumping, high later maintenance cost, large potential safety hazard and the like, and increased risk; if the water pump and the water tank are both placed on the ground, the water pump cannot normally operate according to the existing system, and the use environment of the equipment is greatly limited; to the higher occasion of the aqueous humor liquid level that needs to purify, if the water pump is placed in the position higher than the liquid level, then need place the top of basin in, and the top of basin is not convenient for place other parts usually, and the water pump sets up the position higher, also is not convenient for shift position.
Another method is to directly submerge the submersible pump into the water body to be purified, so that the water pump can normally operate and can also pump water into the water pump, but great inconvenience is brought to later-stage equipment maintenance, meanwhile, if the submersible pump is in a dangerous gas or liquid environment, great potential safety hazard exists in the submersible pump, and the submersible pump is very inconvenient when the water pump needs to be maintained in the later stage; if need maintain equipment, perhaps need still need fish out the water pump when purifying in the water in other regions, shift to other positions again and maintain, it is more inconvenient.
Meanwhile, the existing water pump only solves the problem of water flow generally, and can not solve the problems of improving the dissolved oxygen degree in water, improving water quality, improving survival rate of aquatic products, increasing yield and the like.
