Embodiment approach 1

[0006] Implementation method 1. Weigh 50kg of clay, 35kg of loess, 10kg of kaolin, and 5kg of bamboo powder according to the formula. The kaolin is dried and crushed through a 100-mesh sieve and 100-mesh bamboo powder is put into a mixing kettle, stirred and mixed for 30 minutes, and then the mixed The raw material is put into the rotary disc granulator, and then an appropriate amount of water is added for granulation. The material stays in the granulator for 30 minutes, and then puts it into the drying room for drying. After drying, it is added to the high-temperature kiln for sintering. Control at 1200°C for 2 hours to obtain spherical ceramsite.

[0007] Implementation method 2 Weigh 35kg of clay, 50kg of loess, 10kg of kaolin, and 5kg of bamboo powder according to the formula, dry and pulverize the clay, kaolin, and loess to 200 mesh, put them into a mixing kettle with 200 mesh of bamboo powder, stir and mix for 20 minutes, Then put the mixed material into the rotary disc ...

Abstract

The porous filming material for water treatment consists of clay 30-60 wt%, loess 30-60 wt%, kaolin 5-20 wt% and pore creating material 5-20 wt%. The product of the present invention is spherical haydite, and has high mechanical strength, high erosion resistance, high wear resistance and stable physical and chemical properties as well as rich pores, rough surface, great specific surface area, long service life, high adsorption performance, etc. It has high dirt intercepting capacity and high filming efficiency, is suitable for the growth and propagation of microbe and may be used to eliminate organic matter, suspension, nitride, phosphate, etc from water.

Description

technical field [0001] The invention relates to a microporous membrane-hanging filter material for water treatment. Background technique [0002] The current water treatment filter material mainly uses irregular quartz sand as the filter material. The quartz sand filter material has the disadvantages of large water flow resistance, which can easily cause blockage of the air-water backwash filter, difficult backwash, and easy to break. Contents of the invention [0003] The purpose of the present invention is to provide a microporous membrane-hanging filter material, which has high mechanical strength, strong pollution interception ability, high membrane-hanging efficiency, and can effectively remove organic matter, suspended dirt, nitrogen and phosphorus in water. [0004] The present invention is achieved in this way, its main components are clay, loess, kaolin, pore-forming agent, the weight percentage of component is: clay...
