Problems solved by technology

However, due to the action of river gushing water, the added sewage treatment agent is easily washed away and has little effect; if the amount of sewage treatment agent is increased, it is easy to block the river

Embodiment Construction

[0023] The present invention will be further described below in combination with specific embodiments.

[0024] The biological filler of the present invention includes the following parts by weight: 0.01-1 parts of graphene oxide, 2-20 parts of activated zeolite powder, 1-6 parts of carbon fiber powder, 1-6 parts of nano-silver powder, 1-6 parts of filler I, filler Ⅱ 1-6 copies. Among them, filler I is alumina, silicon oxide, calcium oxide, potassium oxide or iron oxide; filler II is aluminum oxide, silicon oxide, calcium oxide, potassium oxide or iron oxide; filler I and filler II are different Element.

[0025] Biological treatment plays an important role in today's various types of wastewater treatment. The use of biological fillers is a better way to treat sewage. It can not only increase the concentration of microorganisms, increase the BOD load, and the efficiency of nitrogen removal, but also reduce the area occupied and the amount of sludge produced, and enhance the ...

Abstract

The invention provides biological packing. The biological packing is prepared from components in parts by weight as follows: 0.01-1 part of graphene oxide, 2-20 parts of activated zeolite powder, 1-6parts of carbon fiber powder, 1-6 parts of nanometer silver powder, 1-6 parts of filler I and 1-6 parts of filler II. The biological packing is low in use cost, resistant to load impact, good in hydrophilicity and high in biological activity, has a large specific surface area, can purify sewage in flowing water, is less influenced by current scour, is high in sewage treatment efficiency and good in sewage treatment effect and convenient to use and cannot block river channels. The biological packing is suitable for sewage treatment projects such as nitrogen and phosphorus removal and the like of high-concentration organic wastewater, various types of industrial wastewater, refinery wastewater, commodity chemical wastewater, pharmaceutical wastewater and municipal domestic sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to a biological filler and its preparation method and application. Background technique [0002] With the development of social productivity, water resources are becoming more and more scarce. Sewage from various industries makes water rich. A large amount of domestic sewage, industrial sewage, aquaculture sewage and planting sewage are discharged into rivers every day, making water resources even more difficult. In short supply. However, the flow of river gushing is relatively large, and it is impossible to completely intercept the sewage, and the sewage treatment is more difficult, especially the high concentration of ammonia nitrogen and total nitrogen in the sewage, which reduces the dissolved oxygen content in the water and destroys the normal state of the water body. The environment caused a large number of aquatic animals and plants to die, causing t...
