Embodiment 1

[0013] Select sugar factory filter mud with water content of 50-60% to dehydrate to 30%. Weigh 15.0Kg of dewatered filter mud, add 85.0Kg of clay for ceramics, and 0.1Kg of carboxymethyl cellulose, mix evenly in a mixer, and make a spherical ceramsite blank with a particle size of 5mm, and sinter at 900°C for 180 minutes . The porosity of the obtained ceramsite is about 20%, the water absorption is about 10%, and the cylinder compressive strength is 7.5Mpa.

Embodiment 2

[0015] Select sugar factory filter sludge with water content of 50-60% to dehydrate to 25%. Weigh 20.0Kg of dewatered filter mud and add 80.0Kg of ceramic clay and 0.1Kg of carboxyethyl cellulose. Mix evenly in a mixer to make a spherical billet with a particle size of 15mm, and sinter at 1000°C for 80 minutes. The porosity of the obtained ceramsite is about 25%, the water absorption is about 12%, and the cylinder compressive strength is 6.5Mpa.

Embodiment 3

[0017] Select sugar factory filter mud with water content of 50-60% to dehydrate to 30%. Weigh 30.0Kg of dewatered filter mud, 70.0Kg of ceramic clay and 0.1Kg of carboxymethyl cellulose. Mix evenly, make a 5×30mm cylindrical billet, and sinter at 1100°C for 40min. The obtained ceramsite has a porosity of about 30%, a water absorption of about 20%, and a cylinder compressive strength of 3.5Mpa.

Abstract

The invention relates to a technique for making multi-hole porcelain granule produced by the filtered mud of the sugar-refinery. The technique comprises the steps as follows: using the waste filtered mud of the sugar-refinery as the material to generate gas which is dehydrated till the water content is less than and equal to 30 percent and through distribution (clay used for of 70.00 to 85.0 percent, dehydrated filtered mud of the sugar-refinery of 15.0 to 30.0 percent, intensifier carboxymethyl cellulose or propyloic fibrin is 0.1 percent of the total dosage of the below material), performaing, moulding with high temperature (800 to 1200 DEG C, 20 to 180min) and acquiring the multi-hole porcelain granule with 20 to 30 percent of poriness, 10 to 20 percent of water absorbing capacity and 1.5 to 7.5 / MPa of cylinder pressing intensity. The multi-hole porcelain granule can be used as the constructional materials, waste water treating filtering materials, etc. The multi-holes porcelain granule has the advantages of simple and convenient preparation method, high product intensity, big extent of porosity, medium water absorbing capacity, low production cost, etc. The multi-hole porcelain granule technique has good environment protection effects of fountain opening and changing the harm to the benefit.

Description

technical field [0001] The invention relates to a clay ceramic product, especially a porous ceramic product and its preparation method, and also relates to the treatment of sewage, which belongs to the field of resources and environment. Background technique [0002] Sugar factory filter sludge is the waste produced when the sugar industry produces sucrose. It contains a variety of organic substances, which are easily corrupted due to high moisture content and pollute the environment. There are as many as nearly one million tons every year. Since there is no comprehensive utilization, most of them are disposed of by landfill, which leads to waste of resources and secondary pollution. So far there is no proper treatment method. Contents of the invention [0003] The purpose of the present invention is to use sugar factory waste filter mud as raw material, through the process of dehydration, batching, embryo making, and high-temperature molding, to obtain porous ceramsite ...
