Abstract
The invention discloses a method for removing ammonia in wastewater. The method comprises the following three steps: 1, adding compressed air into the wastewater and then jetting the wastewater under a high pressure into a reaction vessel, wherein the pressure of the compressed air is between 10 and 20 kg/cm<2>; 2, adding propanetriol into the reaction vessel and mixing the wastewater with the propanetriol; and 3, introducing the mixed wastewater into an air stripping vessel for aeration stripping. The method of the invention has the advantages of simple operation, high stability and high ammonia removal rate over 98 percent in the wastewater.
Description
Technical field
The present invention relates to the treatment process of ammonia in the trade effluents such as chemical industry.
Background technology
The ammonia wastewater source is in chemical fertilizer, coking, petrochemical industry, pharmacy, food, refuse landfill etc., and a large amount of ammonia waste water not only cause water body black smelly, crowd and biological generation toxic action.The ammonia method of wastewater treatment is mainly contained biological process, physico-chemical process and chemical method both at home and abroad at present.Biological method can only be handled low concentration ammonia waste water, physical method processing cost height; During chemical Treatment in the waste water ammonia residual quantity many, also need to handle again.
Summary of the invention
The objective of the invention is for overcoming the deficiencies in the prior art, the method for ammonia in a kind of effective removal waste water is provided.
The technical solution used in the present invention comprises following three steps:
1, add pressurized air in waste water, compressed-air actuated pressure is 10～20kg/cm
2, be injected in the reaction vessel through high pressure again;
2, in reaction vessel, add glycerol, waste water is mixed with glycerol;
3, mixed waste water is entered carry out aeration stripping in the stripping container.
It is simple to operate, stable high that the inventive method has, and ammonia removal rate is up to more than 98% in the waste water.
Embodiment
The present invention adds pressurized air earlier in waste water, compressed-air actuated pressure is 10～20kg/cm
2, be injected in the reaction vessel through high pressure again; In reaction vessel, add glycerol again, waste water is mixed with glycerol; At last mixed waste water is entered and carry out aeration stripping in the stripping container.By weight glycerol: waste water=10～20: 80～90; The aeration stripping time is 1～2 hour.
Put off until some time later bright the present invention with 4 embodiment below.

Embodiment 2
Add pressurized air in waste water, compressed-air actuated pressure is 20kg/cm
2, be injected in the reaction vessel through high pressure again; In reaction vessel, add glycerol, by weight glycerol: waste water=20: 80; Waste water is mixed with glycerol; At last mixed waste water is entered and carry out aeration stripping in the stripping container, the aeration stripping time is 2 hours.Ammonia removal rate reaches 98.5% in the waste water.
Embodiment 3
Add pressurized air in waste water, compressed-air actuated pressure is 15kg/cm
2, be injected in the reaction vessel through high pressure again; In reaction vessel, add glycerol, by weight glycerol: waste water=15: 85; Waste water is mixed with glycerol; At last mixed waste water is entered and carry out aeration stripping in the stripping container, the aeration stripping time is 1.5 hours, and ammonia removal rate reaches 99.5% in the waste water.
Embodiment 4
Add pressurized air in waste water, compressed-air actuated pressure is 18kg/cm
2, be injected in the reaction vessel through high pressure again; In reaction vessel, add glycerol, by weight glycerol: waste water=12: 88; Waste water is mixed with glycerol; At last mixed waste water is entered and carry out aeration stripping in the stripping container, the aeration stripping time is 2 hours.Ammonia removal rate reaches 99% in the waste water.
