Description

A kind of rapidly and efficiently ammonia nitrogen removal agent and its preparation method and application
Technical field
The invention belongs to water-treatment technology field, a kind of rapidly and efficiently ammonia nitrogen removal agent and its preparation are concretely related to Methods and applications.
Background technology
High-concentration ammonia nitrogenous wastewater source very wide and discharge capacity is big, such as chemical fertilizer, coking, petrochemical industry, pharmacy, food, garbage loading embeading Field etc. produces a large amount of high-concentration ammonia nitrogenous wastewaters.A large amount of ammonia nitrogen waste waters, which are discharged into water body, not only to be caused body eutrophication, causes water Body is black smelly, and will increase the difficulty and cost of Water purification, or even to crowd and biological generation toxic action.Pollution administration, Energy-saving and emission-reduction have turned into the important topic of China's the Implement of sustainable development strategy, and ammonia nitrogen waste water is used as the important of body eutrophication Pollutant becomes the emphasis of improvement.Ammonia nitrogen waste water is discharged into after the water bodys such as lake, reservoir, river mouth, bay, will cause the richness of water body Amount reproduction is destroyed the ecological balance of water body by nutrient laden, aquatile particularly algae, causes water quality deterioration, fish dead. Therefore, removing ammonia nitrogen technology just turns into the focus of research and development and application in field of waste water treatment.So must be in waste water Ammonia nitrogen is handled.
Over nearly 20 years, both at home and abroad to having carried out more research in terms of ammonia nitrogen waste water processing, its research range is related to biology Method, the various handling process of physico-chemical process, such as biological method have nitrification and algal culture, but this method can only handle low concentration ammonia Nitrogen waste water, and treatment time is longer, is difficult to control in actual applications, can suppress the growth of microorganism for ammonia nitrogen in high density, And nitric efficiency is not high；Physical method has counter-infiltration, distillation etc., there is processing cost height, can not be used in big production；Chemistry Method has ion-exchange, ammonia aeration, chemical precipitation method, breakpoint chlorination, electrochemical treatments, catalytic pyrolysis etc., and these methods are passed through Ammonia nitrogen is unable to qualified discharge in waste water after single treatment, also needs subsequent treatment.Blow-off method nitric efficiency is high, but ammonia nitrogen not from Fundamentally remove.
The content of the invention
In order to overcome the shortcomings of that prior art is present, the invention provides a kind of rapidly and efficiently ammonia nitrogen removal agent and its preparation Methods and applications.Ammonia nitrogen removal agent of the present invention can voluntarily dissolve in water, noresidue, without secondary pollution, it is simple to operate, only It is short the time required to changing water quality, ammonia nitrogen can be rapidly and efficiently removed, and there is certain removal to imitate COD, total phosphorus, suspension etc. simultaneously Really.
A kind of rapidly and efficiently ammonia nitrogen removal agent, the ammonia nitrogen removal agent includes the component of following weight/mass percentage compositions：Oxidation Agent 5~35%, inorganic coagulant 5~50%, sorbing material 2~40%, calcium salt 1~15%, gas-producing disintegrant 1~20%.
The present invention operation principle be：
