Description
Technical field
The present invention relates to a kind of paper mud and domestic waste biomass environment-friendly renewable sources of energy deodorizer; In addition, the invention still further relates to the preparation method of a kind of paper mud and domestic waste biomass environment-friendly renewable sources of energy deodorizer.
Background technology
Along with the continuous acceleration of socioeconomic develop rapidly and urbanization process, indoor and outdoor surroundings pollution problem becomes increasingly conspicuous.Domestic Waste Collection, life and industrial sludge sewage such as the production that is people such as the discharge of paper mill sludge (paper mud) and life cause very large puzzlement and inconvenience.And if processed not in time, not only easily communicate illness and insect pest, also can contaminated air and water source.In stench and environment, pathogenic bacteria multiplies in a large number and becomes one of environmental hazard, directly affects the quality of life of people, even jeopardizes the health of people, more and more receive the concern of people.
Odorant refers to the material that can cause the varied smelly sense of organum olfactorium.At present, the odorant with the detected by scent of people has kind more than 4000.The impact of stench on people is many-sided.It not only makes a large amount of pathophorous insecticides, bacteria breed procreation, and directly by olfactory system, produces strong impulse effect to respiratory system, nervous system, blood circulation, hormonal system.The effect of short time can engender a repugnance the symptoms such as sense, Nausea and vomiting, stimulates for a long time and can cause the symptom that endocrine disturbance, cardiovascular disease etc. are serious.Therefore, the Air Pollution Prevention Law of China makes strict rules foul gas discharge.
Odor treatment research is the most advanced with the state such as Japanese, Dutch, German.At present, the minimizing technology for stink mainly contains: (1) chemical deodorizing method, comprises oxidizing process, absorption process, absorption method; (2) combustion method, comprises flame combustion, catalytic combustion; (3) physical deodorization method, comprises the method for keeping away of covering, dilution diffusion method etc.; (4) biological odor removal method, mainly utilizes microbial deodorant, is transformed by material frowzy for tool by the physiological metabolism of microorganism.In above method, first three is planted and often removes in stink process " curing the symptoms, not the disease ", can not remove stink at all, even also can cause secondary pollution; Biological odor removal method is not only simple to operation, and safe and efficient, is convenient to promote the use of on a large scale, has good development prospect.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, a kind of paper mud and domestic waste biomass environment-friendly renewable sources of energy deodorizer are provided, this deodorizer has that cost is low, good deodorization effect, simple to operation, safety good, can not cause the advantages such as secondary pollution, the odor treatment for paper mud and domestic waste is of great importance.
The present invention also provides the preparation method of a kind of paper mud and domestic waste biomass environment-friendly renewable sources of energy deodorizer.
