Embodiment 1
[0048] A tubular ceramic membrane for industrial wastewater treatment, made from raw materials of the following weights:
[0049] Yellow mud 8.5kg, fly ash 2.0kg, pore-forming agent 2.5kg, methyl cellulose 0.2kg, dispersant 0.1kg, lubricant 0.1kg, graphene powder 1.0kg, water 2.0kg.
[0050] Yellow mud is the sieve obtained by passing a 600-mesh sieve; fly ash is the sieve obtained by passing an 800-mesh sieve; the pore-forming agent is methyl methacrylate; the dispersant is sodium lauryl sulfate; the lubricant is glycerin.
[0051] The tubular ceramic membrane is prepared by the following steps:
[0052] S1: after mixing yellow mud, fly ash, methyl cellulose, methyl methacrylate, and stirring for 10 minutes to obtain a first mixture; mixing sodium lauryl sulfate, glycerin and graphene powder and stirring for 5 minutes to obtain the second mixture;
[0053] S2: the first mixture in S1, the second mixture and the water of the formula amount are mixed and stirred for 5 minute...
