Problems solved by technology

However, the high price of these plastic products hinders their popularization and application
[0004] Therefore, the fillers in the existing domestic sewage anaerobic purification treatment device mainly have the following problems: one, the treatment efficiency decreases after using for a period of time
2. The cost is high, which affects the popularization and application of domestic sewage anaerobic purification treatment devices
3. Cause secondary pollution
4. Non-renewable

Embodiment 1

[0023] The use of bamboo in the anaerobic purification device of domestic sewage. After drying the mature bamboo, it is processed and put into the filler area of ​​the anaerobic purification device of domestic sewage as filler. The filler can retain more sludge and play the role of degrading organic matter. effect. Mature bamboo refers to bamboos whose growth period is more than one year. Bamboo can be selected moso bamboo.

[0024] Bamboo material has the characteristics of being difficult to be biodegraded in an anaerobic environment, and has the characteristics of good flexibility and easy processing and weaving. Compared with trees, bamboo grows rapidly and absorbs 4 times more carbon dioxide than ordinary trees. It is a renewable, environmentally friendly and excellent biomass material. Bamboo has been widely used as a building material for a long time. The Han Dynasty bamboo Cambodian unearthed in Mawangdui has not rotted after 2,000 years; many places in the ancient s...

Embodiment 2

[0027] The use of bamboo in the domestic sewage anaerobic purification device, the mature bamboo is cut to form bamboo strips, and then put into the filler area of ​​the domestic sewage anaerobic purification device as filler, the filler can retain more sludge and play the role of degrading organic matter .

[0028] For example, after drying the mature bamboo, saw and cut it into 20cm long bamboo stalks, and put them irregularly into the filling area of ​​the anaerobic purification device. The diameter and length can be selected according to actual needs, and the larger diameter is better. Mature bamboo refers to bamboos whose growth period is more than one year. Bamboo can choose Cizhu.

Embodiment 3

[0030] The use of bamboo in the domestic sewage anaerobic purification device, the mature bamboo is processed and woven into various shapes of bamboo products, and then put into the domestic sewage anaerobic purification device as a filler.

[0031] After the mature bamboo is dried, it is processed and woven with bamboo strips to form bamboo products of various shapes. After drying, it can be stacked and placed in the filling area of ​​the domestic sewage anaerobic purification device.

[0032] Mature bamboo refers to the bamboo whose growth period is more than two years. Bamboo can be selected from bamboo. The structure and shape of the bamboo packing is mainly similar to the structure and shape of the existing plastic porous spherical or column packing, and can also be woven into other structures and shapes.

Abstract

The invention discloses an application of bamboos in an anaerobic purification device of domestic sewage. Grown bamboos are put in a packing area of an anaerobic purification device of the domestic sewage as packing, and the packing can block more sludge and microbial strains and better exert the function of degrading organic matters. The invention has the advantages of water resistance, corrosion prevention, low price, strong plasticity, environment protection, sustainability, low cost, wide sources and simple production method.

Description

technical field [0001] The invention relates to the use of a bamboo product, in particular to the use of bamboo in an anaerobic purification device for domestic sewage. Background technique [0002] The domestic sewage anaerobic purification treatment device, also known as the domestic sewage purification biogas digester, is the main technology for the decentralized treatment of domestic sewage in southern my country, and has been widely used. The filler in the domestic sewage anaerobic purification device should be able to retain more sludge and effectively play the role of biofilm in degrading organic matter. However, from the analysis report, the fillers used over the years have not changed much (such as references, Hu Qichun et al. Technical Analysis of the Design Illustration of Biogas Digesters for Purifying Villages and Towns Domestic Sewage, Journal of Agricultural Engineering, 2008, 24 (11): 197-200), Soft fillers and semi-soft fillers are mainly used. Most of the...
