Biological bamboo charcoal as well as preparation process and application thereof

Abstract

The invention relates to biological bamboo charcoal, a preparation process of the biological bamboo charcoal and an application of the biological bamboo charcoal to the government of sewage containing phenol. The biological bamboo charcoal uses bamboo charcoal as a carrier, microbes are immobilized on the bamboo charcoal and comprise pseudomonas biological phase bacterium fluid. According to the preparation process of the biological bamboo charcoal, the bamboo charcoal is used as the carrier, and the domesticated microbes are treated through an oscillation absorption method and are immobilized on the bamboo charcoal, and the microbes the pseudomonas biological phase bacterium fluid. The bamboo charcoal as the biological carrier has the advantages that: (1) the bamboo charcoal has low price, is easy to obtain and realizes the environment-friendly effect; (2) the physical and chemical performance of the bamboo charcoal are stable, and the mechanical intensity and the durability are good; and (3) rich pores on the inner surface and the outer surface of the bamboo charcoal can provide growth and inhabitation places for the microbes. The biological bamboo charcoal has the following advantages in the water treatment application: (1) the biological bamboo charcoal can be repeatedly used, and the cost of the carrier is low; (2) the operation cost is low, and the reaction process is easy to control; and (3) the defect that the bamboo charcoal is easy and fast to reach the absorption saturation during the sewage purification is overcome.

Description

technical field [0001] The invention relates to the field of chemical environmental protection, and more specifically relates to a preparation process of biological bamboo charcoal and its application in the treatment of phenol-containing sewage. Background technique [0002] Activated carbon is used in the field of sewage treatment due to its strong adsorption properties and huge specific surface area. But at present, the price of activated carbon for industrial use is 6,000-7,000 yuan / ton, and the high cost of use limits its application. [0003] Chinese invention patent ZL 200610112961.7 discloses an activated carbon-supported iron oxide catalyst and its preparation method for the treatment of phenol-containing sewage and coking wastewater. It uses ferric chloride and activated carbon as raw materials, loads iron oxide on the activated carbon, dries at 110-120°C for 6 hours, and solidifies at 260-270°C for 12 hours to obtain an activated carbon-supported iron oxide catal...

Problems solved by technology

[0004] But it still has deficiencies: (1) the preparation process needs to be carried out under high temperature conditions, the process is complicated and the conditions are strict; (2) the requirements for the preparation process are high, which indirectly brings about the high cost of the preparation equipment; (3) the preparation raw material is activated carbon, The cost of preparing and obtaining activated carbon is relatively high

[0007] However, when bamboo charcoal is used for sewage treatment, it is easy to reach adsorption saturation quickly and needs to be regenerated, resulting in increased use costs and limiting its wide application.
