Abstract
The invention discloses a preparative technique for bentonite particles. Powdery sodium bentonite is used as raw materials, appropriate sludge is added, after being mixed evenly, the raw materials and the sludge are added with water, stirred to an appropriate viscosity and squeezed into small particles, and the small particles are roasted in a high temperature after being dried. Due to the facts that crystal water in the particles is lost during the roasting process and organics of the sludge are burned, a mass of micro pores are formed, so that multi-hole sludge bentonite particles are prepared, the aim of granulation of the bentonite is achieved, the application fields of the bentonite in water treatment are greatly broadened, meanwhile, the pollution problem caused by the sludge is solved, and resource utilization of the sludge is achieved.
Description
Technical field
The invention belongs to field of Environment Protection, more specifically say a kind of about the bentonite clay particle technology of preparing.
Background technology
Bentonite is a kind of take the clay mineral of montmorillonite as the essential mineral composition, not only have absorption and ion-exchange performance preferably, and aboundresources, low price, with respect to other costs and the higher adsorbents of energy consumption such as active carbons, but Powdered bentonite suspended dispersed is good, have swellability, meet water and form mud, turbidity is high and transparent performance is very poor.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of new adsorbent product and preparation method are provided, utilize not only good decoloring performance of bentonite clay particle that the technical program produces.And have mechanical strength and a more particle hole preferably.
The present invention is achieved by the following technical solutions: take the powdery sodium base bentonite as raw material, add appropriate mud, mix Hou Jiashui and be stirred to appropriate viscosity, be squeezed into molecule, high-temperature roasting after oven dry.In roasting process owing to losing the organic burning of the granule interior crystallization water and mud itself; form a large amount of micropores; thereby make the porous sludge bentonite granules; both reached the purpose of bentonite clay particle; greatly widened the application of bentonite in water treatment; the pollution problem that has simultaneously also solved sludge creation realizes the recycling of mud.
The specific embodiment
1, raw material.Sodium bentonite, through ground 200 mesh sieves, moisture percentage in sewage sludge 65% is standby.
2, granulate.Mud and bentonite according to the 1:4 mass ratio, are mixed Hou Jiashui and are stirred to appropriate viscosity, be squeezed into diameter and be the particle of 1 millimeter.
3, sintering.With the particle that makes in 120 ℃ of oven dry, then 800 ℃ of roasting temperatures 5 hours.
Claims (4)
1. a bentonite clay particle technology of preparing, is characterized in that the raw materials used sodium bentonite that is, forms through granulation, sintering.
2. a kind of bentonite clay particle technology of preparing according to right 1, is characterized in that described sodium bentonite need grind 200 mesh sieves, moisture percentage in sewage sludge 65%.
3. a kind of bentonite clay particle technology of preparing according to right 1, it is characterized in that described granulation be with mud and bentonite according to the 1:4 mass ratio, mix Hou Jiashui and be stirred to appropriate viscosity, be squeezed into diameter and be the particle of 1 millimeter.
4. a kind of bentonite clay particle technology of preparing according to right 1 is characterized in that described sintering is that the particle that will make is in 120 ℃ of oven dry, then 800 ℃ of roasting temperatures 5 hours.
