preparation example Construction

[0031] The preparation method of the sewage treatment ceramic membrane prepared by using 3D printing technology comprises the following steps:

[0032] S1: Soak diatomite, montmorillonite, calcium silicate, activated carbon, zeolite, and attapulgite in deionized water to wash off the attached pollutants, then dry them until the water content is ≤2%, and then dry them The diatomite, montmorillonite, calcium silicate, activated carbon, zeolite, attapulgite, and carbon fiber, titanium dioxide particles, alumina powder, magnesium oxide powder, and glass fiber are put into the nano pulverizer at a speed of 1000-1200r After pulverizing for 1-1.5h at / min, pass through a sieve to obtain mixture A;

[0033] S2: Put the mixture A, polyhydroxyvalerate, polybutylene succinate, initiator, catalyst and toughening agent prepared in step S1 at a temperature of 220-260°C and a speed of 400-600r / min After stirring for 2-3 hours, put it into a nano pulverizer to pulverize to obtain the mixture...

Abstract

The invention discloses a ceramic membrane for sewage treatment prepared by 3D printing technology and a preparation method thereof. The ceramic membrane comprises the following raw materials: diatomite, montmorillonite, calcium silicate, activated carbon, zeolite, attapulgite, carbon fiber , polyhydroxyvalerate, polybutylene succinate, titanium dioxide particles, alumina powder, magnesium oxide powder, glass fiber, initiator, catalyst, tackifier, toughener, coagulant, stabilizer, The ceramic membrane is made through the steps of decontamination, drying, mixing, and laser scanning sintering under the established three-dimensional file model. The sewage treatment ceramic membrane prepared by 3D printing technology in the present invention is rich in activated carbon, attapulgite, zeolite, etc., which can effectively absorb heavy metal ions, isolate non-beneficial bacteria and a large number of pollutants, etc., and only some trace elements and water molecules can pass through. The formed water indicators all meet the national "Drinking Water Sanitation Standard" (GB5749‑2006).

Description

【Technical field】 [0001] The invention belongs to the technical field of membrane material preparation, and in particular relates to a ceramic membrane for sewage treatment prepared by 3D printing technology and a preparation method thereof. 【Background technique】 [0002] At present, problems such as shortage of water resources, serious water pollution, and deterioration of water ecological environment in my country have become increasingly prominent, and have become the main bottleneck restricting the sustainable development of the economy and society. Domestic sewage is one of the main pollution sources of water bodies. Domestic sewage is mainly various detergents and sewage, garbage, feces, etc. used in urban life. Most of them are non-toxic inorganic salts. Domestic sewage contains a lot of nitrogen, phosphorus and sulfur. , There are many pathogenic bacteria. The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely rela...
