Embodiment 1

[0039] Embodiment 1 of the water treatment method of the present invention is used for aquaculture water body control, and the structure of the water treatment algae box can refer to the above-mentioned embodiment, including the following steps:

[0040] 1) Harden all the fish ponds, put floating water treatment algae boxes in the natural breeding area, the algae boxes are full of rhizomes, and are also equipped with 5W LED lamp beads, all water treatment algae boxes account for 30% of the water area, Among them, 50% of the water treatment algae box adopts the form of mesh bottom wall, and the remaining 50% of the water treatment algae box adopts the form of inverted conical bottom wall. The side length of the water treatment algae box is 1m, and the total area of ​​the connecting holes is 20cm 2 , the water pump connected to the sewage pipe of the water treatment algae tank is turned on once a day, and the water is pumped for 3 minutes each time. The waste water pumped out pas...

Embodiment 3

[0051] Embodiment 3 of the water treatment method of the present invention is used for the cultivation of unicellular algae, and the structure of the water treatment algae box can refer to the above-mentioned embodiment, including the following steps:

[0052] 1) Fully harden the pool body, the water depth is 1 meter, and place a water treatment algae box with a side length of 1m in the breeding area. The water treatment algae box is full of rhizome algae, and 10W LED lamp beads are also arranged. The tank occupies 30% of the surface area of ​​the water body, and all adopt the form of mesh bottom wall;

[0053] 2) The sediment deposited at the bottom of the pool is discharged through the sedimentation discharge pipe, and the water pump connected to the sedimentation discharge pipe is turned on 6 times a day, 10 minutes each time, the collected algae water is settled by the settler to recover the microalgae, and the supernatant is treated by sand filtration Return to the pool b...

Abstract

The invention relates to a water treatment alga tank, a water treatment system and a water treatment method. The water treatment system comprises a system main body and a water treatment alga tank, wherein the system main body is used for containing a water body to be purified; the water treatment alga tank floats on the surface of the water body to be purified; the water treatment alga tank comprises a tank body; an inner cavity for containing filamentous algae is arranged inside the tank body; a communicating channel for communicating an external water body to be purified with the inner cavity is formed in the tank body. By adopting the water treatment alga tank provided by the invention, a great amount of nutrient substances such as carbon sources, N and P are absorbed by the filamentous algae from a water body, dissolved oxygen can be provided for the water body, and ecological functions of the water body can be maintained; the tank body provides a stable spatial environment for the filamentous algae, adaptability of algae and ambient water bodies is intensified, and biological purification functions of the algae can be efficiently brought into play; due to adoption of the communicating channel, exchange of the water body inside the tank body with the external water body can be achieved, and the purpose of ecological treatment on the external water body is achieved; the water treatment system is simple in structure, low in sewage treatment cost and good in effect.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a water treatment algae box, a water treatment system and a water treatment method. Background technique [0002] With industrial progress and social development, the problem of water pollution is becoming more and more serious. The main pollutants in ordinary sewage are COD, ammonia nitrogen, nitrate nitrogen and phosphate. These pollutants will promote the growth of microorganisms, deplete oxygen, cause the water body to stink, and kill fish and shrimp. [0003] Traditional biological sewage treatment methods such as activated sludge method have a good effect on the removal of organic matter and suspended matter in polluted water, but the treatment process consumes a lot of energy, and the treatment effect of total phosphorus and total nitrogen is unstable; a large amount of sludge will be produced during the treatment process. It brings about the problem of high sl...
