Abstract

The invention discloses a treatment agent applicable to food industry sewage and a preparation method therefor. The treatment agent is prepared by employing urea-formaldehyde resin, tert-butyl methacrylate and sodium carboxymethyl starch as main ingredients, adding polyaluminosiloxane, high-nitrogen polyisobutylene succinimide, dodecyl dimethyl benzyl ammonium chloride, triethanolamine, acryloyl morpholine, borax, ferric sulfate, gallic acid, xylanase, phanerochaete chrysosporium powder, an initiator and a coupling agent, and carrying out procedures such as ultrasonic treatment, high-temperature calcination, mixed ball-milling, high-temperature stirring, sprinkling granulation and low-temperature drying. The prepared treatment agent can be used for remarkably reducing COD, BOD, SS and ammonia nitrogen values of the food industry sewage, can meet the requirements of industry and has a relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of sewage comprehensive treatment, in particular to a treatment agent suitable for food industrial sewage and a preparation method thereof. Background technique [0002] The food industry has a wide range of raw materials, a wide variety of products, and a large amount of water is used in the processing process, so a lot of waste is discharged in the form of sewage. The quantity and quality of discharged sewage vary widely. Among them, the main pollutants in sewage are: solid substances floating in sewage, such as vegetable leaves, fruit peels, minced meat, poultry feathers, etc.; substances suspended in sewage include food processing, protein, starch, colloidal substances, etc.; dissolved in sewage acids, alkalis, salts, sugars, etc.; silt and other organic matter entrained in raw materials; pathogenic bacteria, viruses, etc. [0003] At present, there are mainly physical, chemical and biological methods ...
