[0020] Embodiment 1

[0021] Compared with the tail water treatment technology in the prior art, the utility model can efficiently remove excessive substances such as nitrogen and phosphorus in the water. It can effectively purify the tail water through step-by-step treatment in multiple treatment pools, thereby greatly saving the cost of tail water treatment.

[0022] like Figure 1 As shown, a system for treating aquaculture tailwater includes a coarse filtration pool 1, a planting pool 2, a filter pool 3 and a water diversion channel 4. The opposite sides of the planting pool 2 are connected to the coarse filtration pool 1 and the filter pool 3 respectively through the water diversion channel 4. A water diversion channel 4 is also provided on the side of the coarse filtration pool 1 away from the planting pool 2 for water intake. A water diversion channel 4 is also provided on the side of the filter pool 3 away from the planting pool 2 for water discharge; a coarse filtration dam 11 is provided in the coarse filtration pool 1. Large-leaf nine-crown plants are evenly planted in the planting pool 2. A filter material 31 is provided in the filter pool 3. The aquaculture tailwater passes through the coarse filtration pool 1, the planting pool 2 and the filter pool 3 in sequence and is filtered and discharged.

[0023] Furthermore, a valve 41 is provided on the water diversion channel 4. The valve 41 can control the inflow and outflow and the stationary state of the tail water in the system.

[0024] Furthermore, the coarse filter dam 11 is provided with a three-layer structure, which is a pebble layer 111, a brush layer 112 and a river sand layer 113 in the direction of water flow. The coarse filter dam 11 divides the coarse filter pool 1 into two parts, one part introduces tail water, and the other part discharges filtered tail water.

[0025] like Figure 2 As shown, further, a number of planting pots 21 are evenly arranged in the planting pool 2. The planting pot 21 is composed of a ceramic ring 211 and a planting basket 212 installed in the ceramic ring 211, and the planting basket 212 is planted with a large-leaf nine-crown plant. Large-leaf nine-crown is a common aquatic plant. When the large-leaf nine-crown plant appears as an aquatic grass, the young leaves are tea red and the leaves also have 5 long veins, but when it grows into an adult leaf, 2 of the veins are not obvious or disappear directly; the color of the adult leaf also changes to emerald green accordingly; the leaf shape is quite distinctive, the front half of the leaf is wavy, and the whole is linear. The aquatic plant has a large biomass, strong ability to adapt to the environment, and good ability to remove nitrogen and phosphorus; the large-leaf nine-crown planting method adopts a planting pot 21, and one aquatic plant is planted in one planting pot 21, and they are arranged side by side at the bottom of the planting pool 2. The arrangement method is perpendicular to the outlet of the water diversion channel 4, which effectively blocks the impact of water flow while allowing the leaves to fully contact the tail water, increasing the leaf utilization area of ​​the large-leaf nine-crown plant and maximizing the effect of utilization; at the same time, the use of planting pots 21 to plant large-leaf nine-crown plants is convenient for replacement and maintenance, providing convenience for subsequent care.

[0026] Furthermore, the filter material 31 includes a coral stone layer 311 arranged around the filter pool 3, and a filter ball layer 312 surrounded by the coral stone layer 311. The filter material 31 has many pores and good filtering effect, and is easy to provide a good environment for nitrifying bacteria.

[0027] Furthermore, the coarse filtration dam 11 is perpendicular to the flow direction of the water flow, and both ends thereof abut against the inner walls of both sides of the coarse filtration tank 1 .

[0028] Working principle:

[0029] The tail water is introduced into the coarse filter pool 1, and the coarse filter dam 11 introduces the tail water after removing floating impurities into the planting pool 2 for three to four days. The large-leaf nine-crown plant can effectively reduce the total nitrogen and total phosphorus content in the tail water. Then the treated tail water is filtered through the coral stone layer 311 and the filter ball layer 312 in the filter pool 3 to obtain purified water, and the tail water meets the secondary discharge standard.
