Novel ammonia nitrogen biotreatment device

Abstract

The invention discloses a novel ammonia nitrogen biotreatment device comprising raw water supply equipment, raw water treatment equipment and water outlet equipment, which are connected in sequence, wherein the raw water treatment equipment comprises a water distributor, a facultative layer and an aerobic layer; the water distributor is connected with the raw water supply equipment; the facultative layer is perpendicularly mounted at the lower end of the water distributor; the aerobic layer is perpendicularly mounted at the lower end of the facultative layer; the aerobic layer is connected with the water outlet equipment; the facultative layer is uniformly filled with zeolite; and the aerobic layer is uniformly filled with clinoptilolite. The novel ammonia nitrogen biotreatment device comprehensively utilizes the measures of adsorption, ion exchange, biodegradation and the like, can synchronously remove pollutants such as CODcr, ammonia nitrogen, suspended matters and feculence, and has a good treatment effect as well as the advantages of long service life, energy conservation, low operation cost, small occupied area, labor conservation and the like.

Description

technical field [0001] The invention relates to ammonia nitrogen treatment equipment, in particular to a novel ammonia nitrogen biological processor with simple structure, low cost and easy operation. Background technique [0002] Ammonia nitrogen biological processor is a new biochemical removal device for ammonia nitrogen and CODcr. Ammonia nitrogen and CODcr are important pollution indicators for energy saving and emission reduction. If the water body of rivers, lakes and seas is polluted by it, the water body will become smelly and algae will be produced. , the water body is seriously hypoxic. At present, ammonia nitrogen and CODcr are pollutants that must be treated in industrial wastewater and domestic sewage. The treatment methods include biochemical treatment and physical and chemical treatment; The method of denitrifying microorganisms to deal with ammonia nitrogen and CODcr requires a long period of cultivation and acclimation, and the volume is very large, and the...

[0002] Ammonia nitrogen biological processor is a new biochemical removal device for ammonia nitrogen and CODcr. Ammonia nitrogen and CODcr are important pollution indicators for energy saving and emission reduction. If the water body of rivers, lakes and seas is polluted by it, the water body will become smelly and algae will be produced. , the water body is seriously hypoxic. At present, ammonia nitrogen and CODcr are pollutants that must be treated in industrial wastewater and domestic sewage. The treatment methods include biochemical treatment and physical and chemical treatment; The method of denitrifying microorganisms to deal with ammonia nitrogen and CODcr has a long cultivation and acclimation period, and the volume is very large, and the investment is high and the management is complicated.

Physical and chemical methods such as ion exchange, reverse osmosis, etc. also have high investment and high operating costs, while chemical methods such as ion exchange, breakpoint chlorination, and electrochemical treatment are all investment-intensive, cumbersome to operate, and high in operating costs.

Although some people currently use natural zeolite for adsorption and ion exchange to remove ammonia nitrogen, the regeneration of chemical agents is required, the operation is relatively complicated, the consumption of chemical substances is relatively high, and there are still certain problems.
