product description

I. Water quality analysis:

Aquaculture wastewater Aquaculture wastewater has the typical "three high" characteristics, namely high organic matter concentration, COD as high as 3000-12000mg / l, ammonia nitrogen as high as 800-2200mg / l, suspended matter SS exceeding the standard by dozens of times; general biochemical properties; large odor; washing The discharge time is concentrated and the impact load is large. According to the characteristics of the sewage, the biochemical method + physical and chemical treatment method can achieve a good treatment effect.

Second, process selection:

According to the characteristics of the specific sewage water quality of this project, this plan intends to use the conventional "anaerobic + air flotation machine (dosing) + A / O / O biological contact oxidation + disinfection equipment" process, the treatment process is relatively mature, easy to operate The daily cost is low, the water is stable, and the main equipment is a steel structure. Considering the surrounding environment and sanitation issues, the sewage treatment project decided to use a fully buried structure, with the upper part covered with soil, planting flowers and lawns, and further beautifying the environment.

Third, the process:

Fourth, process characteristics:

(1) The technological process is mature, with few structures, flexible operation and convenient management.
(2) The province has a low investment in infrastructure and low operating costs.
(3) The treatment effect is stable, and the quality of the effluent water is good, which can realize decarbonization, nitrogen and phosphorus removal.
(4) The amount of sludge is small, the sludge properties are stable, and the sludge treatment cost is low.
(5) Can withstand the impact of water volume and water quality.
(6) The sewage treatment system has high automation and convenient management.
