Embodiment 1

[0016] Example 1 Take clay to make a spherical billet with a diameter of 28mm, put it into a kiln after natural drying, gradually heat the billet from room temperature to 300°C in 40 minutes, and then heat the billet from this temperature for 50 minutes The heated blank is gradually heated up and sintered until the temperature reaches 800°C, and then the sintered body is gradually cooled to 580°C in 30 minutes, taken out from the kiln, and then cooled naturally.

Embodiment 2

[0017] Example 2 Take clay to make a spherical billet with a diameter of 80mm, put it into a kiln after natural drying, gradually heat the billet from room temperature to 350°C in 50 minutes, and then heat the billet from this temperature for 50 minutes The heated blank is gradually heated up and sintered until the temperature reaches 760°C, and then the sintered body is gradually cooled to 600°C in 25 minutes, taken out from the kiln, and then cooled naturally.

Embodiment 3

[0018] Example 3 Take clay to make a spherical billet with a diameter of 10mm, put it into a kiln after natural drying, gradually heat the billet from room temperature to 300°C in 45 minutes, and then heat the billet from this temperature for 45 minutes The heated blank is gradually heated up and sintered until the temperature reaches 800°C, and then the sintered body is gradually cooled to 600°C in 20 minutes, taken out from the kiln, and then cooled naturally.

Abstract

A process for preparing the microbial carrier to treat sewage by bio-membrane method includes such steps as sphericizing clay with grain diameler of 5-100 mm, natural drying, then loading into a kiln, heating to 300-350 deg.C for 40-50 min, further heating to 750-800 deg.C for 45-50 min, then cooling to 580-600 deg.C for 20-30 min, and further natural cooling to obtain the product.

Description

technical field [0001] The invention relates to the preparation of waste water treatment articles, in particular to the preparation method of microorganism attachment carrier for waste water biochemical treatment. Background technique [0002] Wastewater usually contains a large amount of organic matter, many of which are toxic and harmful substances. The biochemical treatment of wastewater (referred to as biochemical treatment) is generally in contact with microorganisms and wastewater. One of the mechanisms is that the organic matter in the wastewater becomes a nutrient source for the growth and reproduction of microorganisms, which decomposes the organic matter and synthesizes the proteins required for microbial growth. Elements are oxidized and recombined to become non-toxic substances, such as generating CO 2 , N 2 、H 2 O et al. Microorganisms continue to grow and multiply, organic matter is continuously reduced, and the wastewater is purified. F...
