Abstract
The invention provides a method for preparing ultralight porcelain granules, which belongs to the technical field of sewage treatment and utilization. The method uses dewatered sludge from urban sewage plants and clay as raw materials to produce the porcelain granules by high-temperature sintering according to proportion. The porcelain granules are rufous or russet spherical solids with rough surfaces, with loose volume weight of between 300 and 500 kilogram/meter<3>, granule volume weight of between 867 and 975 kilogram/meter<3>, and water absorption rate of between 1.0 and 10.4 percent. The method has the advantages of simple process, low cost, economy, practicality and so on. The prepared porcelain granules have the characteristics of light weight, high strength, low water absorption rate, large specific surface and the like. The method can be widely applied to construction, environmental protection, metallurgy, chemical engineering, petroleum, agriculture and other fields.
Description
Technical field
The present invention relates to a kind ofly prepare the method for Superlight ceramsites, belong to technical field of sewage treatment and utilization with municipal sewage sludge.
Background technology
Sewage plant sludge is meant the flock that produces in the water treatment procedure, it contains nutritive elements such as large quantity of moisture, abundant organism and N, P, K, also contain objectionable impuritiess such as heavy metal and pathogenic bacteria simultaneously, if discharging does not add processing arbitrarily, not only environment being polluted, also is simultaneously the serious waste to resource.According to incompletely statistics, national quantity of wastewater effluent is 4.474 * 107m
3/ d, the sewage work of different scales, different treatment degree has more than 100.The sludge quantity that produced every day is about the 0.5%-1.0% of sewage load, in the mud except that containing nutrition such as abundant nitrogen, phosphorus, also contain a large amount of organism, heavy metal and various pathogenic microorganism, big, easy corrupt, unstable, the foul smelling of its capacity, if handle badly, will cause large-scale secondary pollution; Therefore simultaneously, the investment and the working cost of sludge treatment huge (accounting for the 12%-30% and the 20%-50% of full factory of sewage work expense respectively) sought cost-effective minimizing, pollution processing and utilizing technology innoxious and resource utilization is significant.
The resource technology of current mud mainly contains: 1, the forest land, farmland utilizes; 2, digestion producing methane; 3, turning sludge into fuel technology; 4, building materials utilization; 5; Make cakingagent; 6, low temperature pyrogenation system oil; 7, produce gac or the like.These recycling modes mainly are to carry out at the organic composition in the mud, are to make full use of organic and inorganic two kinds of compositions in the mud and utilize the firing sludge Superlight ceramsites.
Superlight ceramsites is to be main raw material by clay, mud etc., through the particulate state ceramic thing of processing, roasting forms, be characterized in having perfectly round shape profile, shell is hard and has the glaze layer parcel that one deck water proof is protected gas, inside has more hole, it is cellular to be grey black, it is loose, and unit weight is 300-500kg/m
3, and have certain intensity.It is a kind of material of construction preferably and environment-friendly materials, can be used for the starting material of material of construction such as waterproof, fire prevention, insulation, sound insulation, sorbent material, and the filtrate of water treatment reaches the substratum of the soilless culture in agricultural, the gardens etc.Fire this environment difficult problem of treatment and disposal that light ceramic has not only solved mud with mud as raw material, also realized the resource utilization of mud, turn waste into wealth, have significant environmental benefit, social benefit and economic benefit.
Summary of the invention
For overcoming the deficiencies in the prior art, what the invention provides that a kind of technology is simple and direct, cost is low, economic and practical prepares the method for Superlight ceramsites with municipal sewage sludge.
The present invention is a main raw with municipal sewage sludge and clay, best proportioning is screened, according to each principal element in the sintering procedure,, determined to fire the optimum process condition of Superlight ceramsites as the influence of preheating temperature, warm up time, the bloated temperature of burning and bloated time of burning to product performance.
A kind ofly prepare the method for Superlight ceramsites with municipal sewage sludge, step is as follows:
(1), takes by weighing oven dry, the municipal wastewater treatment plant sanitary sewage dewatered sludge after pulverizing and each 1-4 part of clay and 6-9 part places container, adds water and stirs, and up to being thick, makes raw material ball then in weight part;
(2) raw material ball is placed dry 10-20h under the normal temperature;
(3) again raw material ball is put into 350-400 ℃ of chamber type electric resistance furnace, transferred to 1150 ℃ tubular electric resistance kiln roasting 5-15min behind the preheating 10-30min immediately, place the room temperature cooling can obtain Superlight ceramsites haydite.
Superlight ceramsites of the present invention, its outward appearance are russet or Vandyke brown, shaggy globular solids, and loose volume weight is 300-500kg/m
3, particle unit weight is 865-975kg/m
3, can be floating in water, water-intake rate is 1.0-10.4%.
The present invention has the advantages that technology is simple and direct, cost is low, economic and practical, and the haydite that makes has lightweight, high-strength, characteristics such as water-intake rate is little, specific surface area is big, has purposes widely in departments such as building, environmental protection, metallurgy, chemical industry, oil, agriculturals.
