Embodiment 1

[0021] This embodiment provides a kind of biomass sludge ceramsite, and its preparation method comprises the following steps:

[0022] (1) Weigh 60g of biomass co-burning ash, 30g of sludge powder, and 15g of fly ash, and set aside. Among them, the preparation method of biomass co-firing ash is as follows: after mixing 25g of rice husk powder, 20g of sawdust powder, and 60g of sludge powder, they are placed in a muffle furnace at 700°C for calcination for 3 hours, and then cooled to room temperature, the biomass co-burning ash can be obtained.

[0023] (2) Mix biomass co-burning ash, sludge powder and fly ash, and then process them into granules no smaller than 1 cm in diameter to obtain granular materials.

[0024] (3) Put the granular material in an oven at 100°C for 10 minutes, then place it in a muffle furnace at 500°C for 10 minutes, and then heat it up to 1000°C at a rate of 20°C / min for calcination Treat for 10 minutes and cool down to room temperature naturally to ge...

Embodiment 2

[0026] This embodiment provides a kind of biomass sludge ceramsite, and its preparation method comprises the following steps:

[0027] (1) Weigh 80g of biomass co-burning ash, 10g of sludge powder, and 5g of fly ash, and set aside. Among them, the preparation method of biomass co-firing ash is as follows: after mixing 45g of rice husk powder, 10g of sawdust powder, and 40g of sludge powder, they are then calcined in a muffle furnace at 900°C for 3 hours, and then cooled to room temperature, the biomass co-burning ash can be obtained.

[0028] (2) Mix biomass co-burning ash, sludge powder and fly ash, and then process them into granules no smaller than 1 cm in diameter to obtain granular materials.

[0029] (3) Put the granular material in an oven at 110°C for 20 minutes, then place it in a muffle furnace at 600°C for 20 minutes, and then heat it up to 1200°C at a rate of 50°C / min for calcination Treat for 20 minutes and cool down to room temperature naturally to get biomass ...

Embodiment 3

[0031] This embodiment provides a kind of biomass sludge ceramsite, and its preparation method comprises the following steps:

[0032] (1) Weigh 65g of biomass co-burning ash, 25g of sludge powder, and 12g of fly ash, and set aside. Among them, the preparation method of biomass co-firing ash is as follows: after mixing 30g of rice husk powder, 16g of sawdust powder, and 55g of sludge powder, they are placed in a muffle furnace at 800°C for calcination for 3 hours, and then cooled to room temperature, the biomass co-burning ash can be obtained.

[0033] (2) Mix biomass co-burning ash, sludge powder and fly ash, and then process them into granules no smaller than 1 cm in diameter to obtain granular materials.

Abstract

The invention is applicable to the field of waste utilization and sewage treatment, and provides biomass sludge ceramsite as well as a preparation method and an application thereof. The biomass sludgeceramsite comprises the following components in parts by weight: 60-80 parts of biomass co-fired ash, 10-30 parts of sludge powder and 5-15 parts of fly ash; the biomass co-fired ash comprises the following components in parts by weight: 25-45 parts of rice hull powder, 10-20 parts of sawdust powder and 40-60 parts of sludge powder. The biomass sludge ceramsite provided by the invention does notconsume any non-renewable natural resources such as shale, kaolin, clay and the like, is uniform in pore size, has relatively low water absorption and a relatively good adsorption effect, and is a very good heavy metal sewage treatment material.

Description

technical field [0001] The invention belongs to the field of waste utilization and sewage treatment, in particular to a biomass sludge ceramsite and its preparation method and application. Background technique [0002] Biomass is a variety of organisms produced by photosynthesis in the atmosphere, water, soil, etc., that is, all living and growing organic substances are called biomass, including animals, plants and microorganisms. Biomass mainly refers to lignin such as straw and trees other than grain and fruit in the process of agricultural and forestry production, and leftovers of agricultural product processing industry, which are the main components of agricultural and forestry waste and animal husbandry waste. my country attaches great importance to the utilization of biomass energy, and the development and investment prospects of biomass energy in China are extremely broad. Sludge is a by-product of sewage treatment in municipal sewage treatment plants. It is an ext...
