Abstract

The present invention discloses one kind of haydite produced with dewatered sludge, fly ash and clay as material and its production process, and belongs to the field of environment technology. The haydite is produced dewatered sludge, fly ash and clay as material, and through mixing and sintering at gradually raised temperature. It is yellow or brown spherical solid in the bulk specific weight of 650-750 kg/cu m, granular specific weight of 1050-1150 kg/cu m, water absorption of 5.80-10.8 %, and specific surface area of 2.29-5.56 sq m/g. The production process is simple and low in cost, and the haydite has light weight, high strength, small water absorption, great specific surface area and other features. The haydite has wide use in building, environment protection, metallurgy, chemical industry, and other industry.

Description

A kind of method with preparing haydite from urban sewage plant sludge
(1) technical field
The present invention relates to a kind of method, belong to the environmental technology field with preparing haydite from urban sewage plant sludge.
(2) 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, and 3. turning sludge into fuel technology, cakingagent is 5. made in 4. building materials utilization, and 6. low temperature pyrogenation system oil is 7. produced gac or the like.These recycling modes mainly are to carry out at the organic composition in the mud, and utilize the firing sludge haydite can give full play to organic and inorganic two kinds of compositions in the mud.
Haydite is to be main raw material by clay, argillaceous rock (shale, slate etc.), industrial waste (flyash, coal gangue), 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, and its loose volume weight is 200~1000kg/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.Not only solve this environment difficult problem of treatment and disposal of mud with mud as the raw material baking ceramsite, also realized the resource utilization of mud, turned waste into wealth, had significant environmental benefit, social benefit and economic benefit.
(3) summary of the invention
The present invention is main raw material with the municipal sewage sludge, with flyash and clay is auxiliary material, best proportioning is screened, and investigated each principal element in the sintering procedure (time of drying, preheating temperature, warm up time, burning expand temperature and bloated time of burning) and, determined the optimum process condition of baking ceramsite the influence of product performance.
A kind of method with preparing haydite from urban sewage plant sludge, step is as follows:
(1) in weight part, take by weighing oven dry, municipal wastewater treatment plant sanitary sewage dewatered sludge, flyash, each 15-25 part of clay, 25-35 part, 10-15 part after pulverizing, place container, add water and stir, up to being thick, make raw material ball then;
(2) raw material ball is put into electric heating constant temperature air dry oven dry 1h under 105 ℃;
(3) again raw material ball is put into chamber type electric resistance furnace and is warming up to 200 ℃, warm up time 10min; Continuation is warming up to 1100 ℃ in chamber type electric resistance furnace, roasting 5min; Naturally cool to room temperature, make haydite.
Wherein, contain SiO in the above-mentioned described sanitary sewage dewatered sludge 2Be no less than 30%; Described flyash contains SiO 2Be no less than 50%, Al 2O 3Be no less than 20%; Clay contains SiO 2Be no less than 60%, Al 2O 3Be no less than 15%.
Haydite of the present invention, its outward appearance are the globular solids of yellow or brown, and loose volume weight is 650-750kg/m 3, particle unit weight is 1050-1150kg/m 3, water-intake rate is 5.80-10.8%, specific surface area is 2.29-5.56m 2/ g.
The haydite that the present invention 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.
