Description
Technical field
The invention belongs to environmental ecology technical field, and in particular to one kind prepares air cleaning using sludge and feces of livestock and poultry
Material and the method for composite fertilizer.
Background technology
The substantial amounts of excess sludge of sewage treatment plant's discharge is a great problem of environmental area.At present, various countries are frequently with defending
The method processing such as raw landfill and burning.But sanitary landfills has Environmental security hidden danger, burning method high cost, and easily pollution is big
Gas.Contain the nutritional ingredient such as substantial amounts of organic matter and nitrogen, phosphorus, potassium, amino acid and trace element, many compositions therein in sludge
All it is valuable resource.Thus, the method for comprehensive utilization of sludge is actively inquired into, turns waste into wealth, is the best outlet of sludge treatment.
But also containing heavy metal and toxic organic compound in sludge simultaneously, traditional compost method can not be removed effectively.Li Lingzhi et al.
（ZL 201310671591.0, a kind of activated sludge fertilizer）By adding EDTA, ferric sulfate, citric acid, potassium fulvate, sorb
The medicament such as sugar alcohol and ZnCl2, fertilizer is made by sludge, although can improve crop yield, but fertilizer prepared by this method does not have
The problem of having consideration pathogen, organic toxic substance and heavy metal；Ao Liaiou（ZL 200880012497.1, from sludge
The method for producing fertilizer）Using overheated steam to Treatment of Sludge, organic fertilizer is prepared for, pathogen, still, sludge has been killed
In heavy metal not yet remove, still there is pollution risk；Soup brilliance and Cao Xianzhong（Application number 201510078197.5, one
Plant the method that ecological fertilizer is prepared by sludge）Using the method for addition sludge heavy-metal blocking agent, sludge ecological fertilizer is prepared for,
Feng Tingting（Chengdu University of Technology's master thesis, 2009, master's modified coal ash passivation municipal sludge in heavy metal and its
In application study agriculturally）It is good using flyash, grand dream（Whiterot fungi is passivated shadow to sludge composting lignin degradation and heavy metal
Ring, Hua Zhong Agriculture University, 2009-06-01 master）Using whiterot fungi, space on daytime（Heat modification concave convex rod is added to weight in sludge
The research of metal passivation effect, Lanzhou Jiaotong University, 2014-04-01, master）Using modified attapulgite etc. to a huge sum of money in sludge
Category is passivated ..., although these methods can temporarily slow down the release of heavy metal, this method is heavy without thoroughly removing
Metal, the heavy metal for entering soil with fertilizer can be discharged, potential hazard is huge in the presence of microorganism etc..Sludge
Another outlet that the material for water treatment such as activated carbon are current sludge is prepared, but sludge phosphorus content is relatively low, impurity content
It is higher, prepare activated carbon high cost.
In traditional agriculture, feces of livestock and poultry is all to be used for agricultural production after compost.But, in modern livestock and poultry cultivation industry
In, in order to improve the yield and quality of meat, eggs and milk, and needs of preventing and curing diseases, it can add substantial amounts of rich in micro member in feed
The nutritional ingredient and various additives of element, after livestock and poultry feed, these materials have greatly can be in the form of original shape with excrement
Homaluria comes out, so, can also be containing a large amount of in feces of livestock and poultry in addition to containing protein, amino acid and cellulose wood quality
The heavy metal such as copper and iron zinc, and the harmful substance such as antibiotic and growth promoter.Traditional composting process, it is impossible to effectively remove this
A little harmful substances, these harmful substances enter soil with muck, can agricultural product and environment be caused with serious harm.Cao enters use
Adsorbent is added in feces of livestock and poultry, the method for mixing after fermentation prepares organic fertilizer（Patent of invention, application number：
201310511848.6, a kind of method that utilization feces of livestock and poultry produces organic fertilizer）.Li Ronghua uses maize straw for conditioning
Agent, using trade waste flyash, weathered coal and bentonite as heavy metal deactivator, fermentation process feces of livestock and poultry（Li Ronghua, west
Northern agriculture and forestry science and technology university, Ph.D. Dissertation, influence research of the addition heavy metal deactivator to Aerobic Compost of Pig Manure, 2013）Deng
Deng.These methods for relying solely on fermentation can not effectively remove the harmful substances such as antibiotic, and the passivation of heavy metal is interim
The state of heavy metal is changed, environmental risk is still there is.
With the aggravation of Indoor Air Pollution with outdoor Air Pollution, material for air purification and device requirement increase sharply.Current material for air purification
With the main active charcoal of equipment（Wei Jingdong, patent of invention：200910187276.4, activated carbon air purifying plate；Min Hailong, Shen
