Problems solved by technology

This method is proposed for the treatment of eutrophication in landscape water bodies, focusing on eliminating algae hydration. Since the source pollutants of eutrophication are not solved, it is only suitable for the treatment of eutrophication in small water bodies, but not suitable for large water bodies such as eutrophication in sea areas. treatment, not suitable for sewage treatment
[0006] In summary, there is currently no feasible, efficient and stable method for completely eliminating eutrophication in sewage and related water purification systems, and it is impossible to effectively alleviate the problem of marine eutrophication

Embodiment 1

[0033] This embodiment provides a method for treating eutrophication substances in sewage through Artemia culture, which includes the following steps: building a treatment pool, and injecting salt field brine into the treatment pool. The sewage to be treated is injected into the treatment pool in a continuous or semi-continuous manner, and the net evaporation rate of the water body in the treatment pool is kept the same as the injection rate of the sewage to be treated. Adjust and maintain the salinity of the water body in the treatment pond at 6°Bé to 14°Bé, cultivate Artemia in the water body in the treatment pond, and catch Artemia adults.

[0034] When the type of sewage to be treated is domestic sewage, the sewage to be treated is first subjected to an aeration step before being injected into the treatment tank. In the aeration step, oxygen-increasing treatment is performed on the domestic sewage, and harmful substances such as ammonia nitrogen and sulfide are oxidized, s...

Embodiment 2

[0038] Such as figure 1 As shown, this embodiment more specifically provides a water purification system applying the method described in the foregoing embodiment 1, including a sewage main pipe 1 and a sewage treatment unit 3, and the sewage treatment unit 3 includes interconnected treatment tanks and aeration pool; the sewage main pipe 1 communicates with the aeration tank through a connecting pipe, and a flow valve 2 is arranged on the connecting pipe. The quantity of described treatment pool is two, and two described treatment pools are respectively interconnected first treatment pool 3-1 and tail treatment pool 3-16, and described sewage treatment unit 3 is also provided with to make sewage between the treatment pools The water pump 4 that circulates between.

[0039] The sewage treatment unit 3 also includes a circulating backwater pool 3-17, the right end of the first treatment pool 3-1 and the tail treatment pool 3-16 are directly connected, and the first treatment po...

Embodiment 3

[0043] Such as figure 2 As shown, this embodiment more specifically provides a water purification system applying the method described in Embodiment 1 above, including a sewage main pipe 1 and two sewage treatment units 3 .

[0044] Each of the sewage treatment units 3 includes a treatment tank and an aeration tank connected to each other; the sewage main pipe 1 and the aeration tank are connected through a connecting pipe, and a flow valve 2 is arranged on the connecting pipe. The quantity of described treatment pool is sixteen (corresponding label among the figure is successively 3-1, 3-2..., 3-16, and the label of head treatment pool is 3-1, tail treatment pool The labels are 3-16), and the sixteen treatment pools are respectively connected in sequence, and the sewage treatment unit 3 is also provided with a water pump 4 to circulate the sewage between the treatment pools.

[0045] The sewage treatment unit 3 also includes a water circulation pool 3-17, and the first trea...

Abstract

The invention provides a method for treating eutrophication substances in sewage through artemia culture. The method includes the following steps that S1, a treating pond is built, and salt lake brine is injected into the treating pond; S2, to-be-treated sewage is injected into the treating pond in a continuous or semi-continuous mode, and the net evaporation speed of a water body in the treating pond and the injection speed of the to-be-treated sewage are kept same; S3, the salinity of the water body in the treating pond is adjusted and kept 6 baume to 14 baume, nutrient substances in sewage are used, microalgae, microorganisms and the like are cultured to serve as baits of artemia, artemia in the water body in the treating pond is cultured, and nitrogen and phosphorus eutrophication substances are removed in sewage from water by catching artemia. By means of the method, it is achieved that the eutrophication substances in sewage are efficiently and continuously purified, zero discharging of the eutrophication substances is achieved, artemia produced in the water purifying process is high-quality baits for culturing animals and raw materials in cooperation with feed, and objective economic benefits can be created.

Description

technical field [0001] The invention belongs to the technical field of purification treatment of eutrophic substances in sewage and artemia culture, and specifically relates to a method and a water purification system for treating eutrophic substances in sewage through artemia cultivation. Background technique [0002] At present, urban sewage is generally treated by physical treatment, microbial treatment and other methods in sewage treatment plants to obtain reclaimed water that meets certain standards. Containing high nitrogen, phosphorus and other nutrients, it will cause eutrophication of the water near the coast where the reclaimed water is discharged. Usually, it is difficult and costly to further reduce total nitrogen and total phosphorus in sewage treatment plants, and the use of chemical phosphorus removal will also produce a large amount of chemical sludge and metal ion residues that are not easy to handle. In addition, the concentration of pollutants such as tot...
