Aquaculture-tail-water treating system and method

Abstract

The invention discloses an aquaculture-tail-water treating system and method. The treating system comprises a first water storage tank, a first water pump, a second water storage tank, a second waterpump, a filtering device and a pipe cultivation device, wherein the first water pump is used for pumping aquaculture tail water into the first water storage tank; the second water pump is used for pumping water in the first water storage tank into the second water storage tank from the upper portion of the first water storage tank, and comprises a water outlet pipe; the filtering device is arranged at a water outlet of the water outlet pipe and used for filtering suspended matter in water pumped from the first water storage tank; the pipe cultivation device comprises multiple cultivation grooves, and at least one of the multiple cultivation grooves is communicated with a water draining opening of the second water storage tank through a pipe. According to the aquaculture-tail-water treatingsystem and method, the aquaculture tail water is subjected to standing and filtered to be fed into the pipe cultivation device, vegetables in the pipe cultivation device are used for absorbing microelements such as N and P in the tail water, the water quality of the aquaculture tail water is thus improved, and a guarantee is provided for achievement of aquatic-product healthful breeding and sustainable development.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and in particular relates to an aquaculture tail water treatment system, and also relates to an aquaculture tail water treatment method. Background technique [0002] In the traditional high-density aquaculture method, a large amount of residual bait and feces are discharged into the water body, which will lead to eutrophication of the water in the breeding pond. If it is not treated in time and effectively, it will not only deteriorate the aquaculture water environment, but also lead to the death of fish, shrimp, crabs and other farmed animals. Diseases occur, and the quality and output of aquaculture products decline; the discharge of aquaculture tail water into outer rivers will have a certain negative impact on the natural water environment. Therefore, providing an environmentally friendly aquaculture tail water treatment system has important practical significance for the healthy and...
