Pastry factory production wastewater treatment agent and wastewater treatment method

Abstract

The present invention belongs to the field of wastewater treatment of food businesses, in particular relates to a pastry factory wastewater treatment agent, and also relates to a pastry factory production wastewater treatment method. The pastry factory wastewater treatment agent comprises a physical purifying agent, complex microbial agents and an enzyme preparation, the physical purifying agent comprises the following components by weight: 1-5 parts of activated carbon, 1-5 parts of organically modified zeolite and 1-5 parts of polyacrylamide; the complex microbial agents comprise 0.02-0.1 part of saccharomycetes powder, 0.05-0.2 part of flocculating bacteria powder, 0.05-0.2 part of bacillus megatherium powder and 0.04-0.2 part of chryseobacterium powder; the enzyme preparation comprises 0.05-0.1 part of xylanase, 0.04-0.09 part of glucose oxidase and 0.01-0.06 part of amylase. According to the pastry factory production wastewater treatment method, wastewater treatment agent wastewater treatment method, the complex, large particle and difficult-to-degrade organic matters are hydrolyzed into easily-degradable simple organic matters, wastewater SS content is greatly reduced, and the treated wastewater has BOD and COD removal efficiency, and reaches prescribed emission standards.

Description

technical field [0001] The invention belongs to the field of waste water treatment of food enterprises, in particular to a treatment agent for pastry factory production waste water, and also relates to the above-mentioned pastry factory production waste water treatment method. Background technique [0002] The wastewater in the pastry industry mainly comes from three aspects: the washing water of the conveying device and the water for cleaning the container. If the raw materials are handled negligently, there will be leftovers of finished or semi-finished products in the wastewater, such as bread crumbs and residues of various additives; (2) Soaking Water and cooking water; (3) Cooling water and condensed water for equipment and containers. [0003] Due to the differences in the production process, production conditions, seasonal changes, etc., the sewage discharged by enterprises in the pastry industry has great differences in the amount and quality of the waste water.

[0004] The discharge of organic wastewater in the cake industry is increasing. The wastewater in the cake industry belongs to the food industry wastewater. It is non-toxic, but usually contains a large amount of biodegradable organic matter, with high COD, BOD and SS values. Concentration of animal and vegetable oils, if such wastewater is discharged directly into the water without treatment, it will quickly and massively consume dissolved oxygen in the water, deteriorating the water quality, causing oxygen in the water body, killing fish and aquatic organisms, and the suspension in the wastewater The waste sinks to the bottom of the river, decomposes under anaerobic conditions, produces odor, deteriorates water quality, and pollutes the environment. If waste water is introduced into farmland for irrigation, germs will cause the spread of diseases and directly endanger the health of humans and animals. Therefore, waste water from the pastry industry must be treated
