Problems solved by technology

[0004] In terms of safety of organic flocculants, although fully polymerized enamine flocculants themselves have no problems, their polymerized monomer, acrylamide, is highly toxic to the nervous system and can also cause bladder cancer

Embodiment 1

[0021] 5% protease, 5% hemicellulase, 10% cellulase, 5% laccase, 5% bacillus, 5% nitrococcus, 0.5% rose flower extract, and make up to 100% with water.

Embodiment 2

[0023] 8% protease, 8% hemicellulase, 15% cellulase, 8% laccase, 6% bacillus, 7% nitrococcus, 1% rose flower extract, and make up to 100% with water.

Embodiment 3

[0025] Protease 10%, hemicellulase 10%, cellulose 15%, laccase 10%, Bacillus 10%, Nitrococcus 10%, rose flower extract 2%, water to make up to 100%.

[0026] The biological enzyme treatment agent for papermaking wastewater of the invention is a complex of biological enzymes and bacteria, including biological enzymes such as cellulase, hemicellulase, protease, laccase and other microorganisms such as bacillus and nitrococcus. It can treat waste water produced in paper mills and similar industries, and accelerate the biodegradation rate of organic substances contained in waste water. The biological enzymes contained in it are specially used to "attack" the long chain of cellulose and accelerate the degradation of such substances; Accelerate the degradation of wastewater, can effectively degrade the characteristics.

Abstract

The invention discloses a biological enzyme treating agent of paper wastewater. The biological enzyme treating agent of the paper wastewater is characterized by comprising, by weight, 5%-10% of protease, 5%-10% of hemicellulase, 10%-15% of cellulose, 5%-10% of laccase, 5%-10% of bacillus, 5%-10% of nitrococcus, 0.5%-2% of rose extracting solution, and the balanced water. The biological enzyme treating agent of the paper wastewater is a compound of the biological enzymes and bacteria and comprises the biological enzymes, such as the cellulose, the hemicellulase, the protease, and the laccase, and microorganisms, such as the bacillus, and the nitrococcus. The biological enzyme treating agent of the paper wastewater is capable of being used for treating wastewater produced by paper-manufacturing factories and similar industries, and accelerating biodegradation of organic matter in the wastewater. The biological enzymes contained by the biological enzyme treating agent of paper wastewater are specially used for 'attacking' long chains of cellulose and accelerating degradation of substances similar to the cellulose. The biological enzyme treating agent of the paper wastewater is capable of accelerating biodegradation of the wastewater and effective in degradation characteristic.

Description

technical field [0001] The invention belongs to the field of combination of biotechnology and environmental technology, and in particular relates to a biological enzyme treatment agent for papermaking wastewater. Background technique [0002] At present, the commonly used water treatment purifiers mainly include two categories: inorganic flocculants and organic polymer flocculants. Each chemical product is a highly targeted product, and it will fail when it encounters other complex chemical substrates; after using chemical products, there will always be chemical residues in the water body, which may bring side effects or new pollution; The use of chemical products can mask the odor, but it cannot change its origin or stop it from escaping. [0003] Aluminum-based flocculants usually use polyaluminum chloride, crystalline aluminum chloride, aluminum sulfate, aluminum hydroxide flakes, etc. to generate charged colloidal ions in water, which can absorb other colloidal ions wi...
