Abstract
The invention discloses a novel method for preparing activated carbon from cattle manure. The influence of related factors on the adsorbability of the prepared activated carbon in the preparation process is inspected to detect the optimal technological parameters and preparation conditions for preparing activated carbon from cattle manure, so that the activated carbon prepared from cattle manure can satisfy the relevant standard, can implement large-scale popularization and application, and can generate economic benefit, social benefit and ecological effect. The method has the following advantages: the raw material for preparing the activated carbon has wide resources and low price, thereby satisfying the requirements for pollution source emission reduction; and the prepared activated carbon has favorable adsorption effects in the aspect of wastewater treatment.
Description
Technical field
The innovation invention relates to the method utilizing the cow dung in the feces of livestock and poultry of rural area to prepare gac, belongs to solid waste resource recovery and utilizes technical field.
Background technology
Along with China's rural economy center of gravity shifts from plant husbandry to livestock industry, livestock industry becomes rural economy new growth point and important mainstay industry gradually in China.Livestock-raising mass-producing, intensive and Mechanization Development produce a large amount of feces of livestock and poultry without any process just directly discharge, cause serious pollution, bring a series of environment and social concern.Current, the recycling of feces of livestock and poultry is mainly concentrated on and makes fertilizer, feed and fuel, and there is not been reported the cow dung in feces of livestock and poultry to be used for make gac.
Gac has highly developed pore texture, large specific surface area and stronger adsorptive power, physical and chemical performance is stablized, water insoluble and other most solvents, are therefore widely used in all respects of industrial and agricultural production as a kind of excellent sorbent material.At present, the raw material preparing gac mainly comprises wood chip, straw, shell (core), mud coal, pitch and rubber, excess sludge etc., is prepared from by physically activated or chemical activation method.Although the raw material preparing gac is numerous, wherein great majority are all subject to the restriction of source and cost, can not apply on a large scale.And feces of livestock and poultry possesses the primary condition preparing gac, and wide material sources, with low cost, therefore utilize feces of livestock and poultry to prepare a kind of method that gac is reasonable, also meets rural area solid waste resource recovery, minimizing, innoxious principle simultaneously.
Summary of the invention
For the severe situation of current rural area Pollution from livestock and poultry, adopt the cow dung in feces of livestock and poultry to be raw material, by analysis for preparation of activated carbon by chemical activation, explore a livestock and poultry dung recovery, minimizing, innoxious new way, realize turning waste into wealth.
For achieving the above object, the technical problem to be solved in the present invention mainly comprises cow dung and prepares the impact of correlative factor on product performance and the optimization of preparation technology in gac process, the structural characterization of cow dung gac and Study on adsorption properties.
The technical solution adopted for the present invention to solve the technical problems mainly comprises following steps:
First pre-treatment is carried out to cow dung, then find out the correlative factor affecting active charcoal preparing process, experimental design is carried out to it, explore optimum processing parameter and preparation condition, finally structural characterization and performance test are carried out to the cow dung gac of preparation, according to test result, constantly improve preparation parameter and condition, make the gac of preparation meet relevant standard.
The invention has the beneficial effects as follows, by rural area solid waste---fowl and animal excrement processing treatment makes gac, make pollutant discharge amount reach minimum, realize the resource utilization of feces of livestock and poultry, innoxious, minimizing, there are economic benefit, social benefit and ecological benefits simultaneously.
Embodiment
(1) under fresh cow dung being placed in sunlight, natural drying is air-dry, often stirs and makes ight soil uniform drying.The ight soil of drying regime is pulverized into particle diameter 2mm ~ 5mm, is stored in sealing bag for subsequent use.
(2) get the cow dung raw material of certain mass to mix by different solid-liquid mass ratioes from the Secondary ammonium phosphate activator of different concns, dipping 24h.
(3) uniform for dipping test sample is put into retort furnace, carbonization 50min at 400 DEG C, continue to be warmed up to certain temperature activation, and keep certain hour.
(4) hydrochloric acid soln of (1+9) is first used to clean activation after product, oxide compound wherein and impurity is impelled fully to dissolve, use the distilled water repetitive scrubbing of about 80 DEG C to neutral again, filter, then put into electric heating constant-temperature blowing drying box dry 16h at 110 DEG C, with glass mortar grinding after cooling, sieve, install with sample sack, put into drying basin for subsequent use.
(5) with iodine sorption value and methylene blue adsorption value for evaluation index, the factor such as solid-liquid mass ratio, activator concentration, soak time, activation temperature of having investigated in preparation process is on the impact of the made charcoal absorption performance of cow dung.
(6) by relevant Modern Analytical Instrument, structural characterization is carried out to cow dung institute preparing active carbon.

Claims (2)
1. a novel absorbent charcoal, is characterized in that taking cow dung as raw material, adopts chemical activation method to make.
2. gac according to claim 1, is characterized in that: the raw material preparing gac is cow dung.
