Problems solved by technology

However, traditional ceramsite mostly uses natural resources such as clay and oil shale slag as the main raw materials, and large-scale mining will destroy the ecological environment.
Currently commonly used ceramsite also has many defects: low porosity, low micropore content, insufficient surface roughness, small specific surface area, poor adsorption capacity, low hardness, fragility, etc., resulting in low water treatment efficiency and poor purification effect. The cost is high, so it affects the popularization and promotion of ceramsite

Embodiment Construction

[0008] The raw materials of the boron mud ceramsite include boron mud, oil shale slag, fly ash, binder, pore-forming agent; the volume percentage of various raw materials consumption in the total amount of raw materials is: boron mud accounts for 35% or 40% % or 45%, oil shale slag 30% or 35% or 40%, fly ash 10% or 13% or 15%, binder 3% or 5% or 7% or 10%, pore-forming agent 5% or 7% or 10%; the binder can be carboxymethyl cellulose or bentonite or clay or diatomaceous earth; the pore-forming agent can be coal powder or carbon powder or calcium carbonate;

[0009] The preparation method of boron mud ceramsite is as follows: mix boron mud, oil shale slag, fly ash, binder, and pore-forming agent according to the ratio stated in the formula, put them into a ball mill and add water for ball milling, and the ball-milled mud is squeezed After the water is squeezed out by the machine, it is dried, and then the dried mud is crushed into powder and then shaped in a molding machine to m...

Abstract

The invention relates to boric sludge ceramsite which is used for a filter material of raw water biological pretreatment and sewage advanced treatment and also can be used for lightweight aggregate concrete aggregate and a preparation method of the boric sludge ceramsite. The boric sludge ceramsite is invented to mainly solve the problems that existing ceramsite is low in porosity, low in water treatment efficiency and the like. The boric sludge ceramsite is prepared from, by volume, 35%-45% of boric sludge, 30%-40% of oil shale dregs, 10%-15% of fly ash, 3%-10% of binder and 5%-10% of pore-forming agent. The preparation method includes the steps that blending is conducted according to the proportion of the formula, the materials enter a ball mill to be added with water for ball-milling, the ball-milled sludge is dried after moisture is drained, and a dried sludge block is crushed to be in a powder shape and then is formed to be made into a straight spherical particle raw material; the spherical particle raw material is placed in a rotary kiln to be dried, preheated, roasted and cooled to a normal temperature, and the running time of spherical particles in the kiln is about 60 minutes altogether. The boric sludge ceramsite has the advantages of being high in porosity and high in water treatment efficiency.

Description

Technical field: [0001] The invention belongs to the field of building material engineering, and in particular relates to a filter material used for biological pretreatment of raw water and advanced treatment of sewage, boron mud ceramsite which can also be used for light aggregate concrete aggregate and a preparation method thereof. Background technique: [0002] At present, with the deepening of people's understanding of ceramsite, ceramsite is more and more widely used as water treatment filter material and lightweight aggregate. Traditional ceramsite mostly uses natural resources such as clay and oil shale slag as the main raw materials, and large-scale mining will destroy the ecological environment. Currently commonly used ceramsite also has many defects: low porosity, low micropore content, insufficient surface roughness, small specific surface area, poor adsorption capacity, low hardness, fragility, etc., resulting in low water treatment efficiency and poor purificati...
