Problems solved by technology

The current treatment method is that the intestinal membrane protein is obtained by filtering, concentrating, and spray-drying the wastewater. The intestinal membrane protein is easily digested and absorbed by piglets, but it has a unique fishy smell of the small intestine, and its use is limited.

Embodiment

[0022] The wastewater produced by the production of heparin sodium by enzymatic hydrolysis is 5000 liters. Add 10 kilograms of polyaluminum chloride and 50 ppm of 6 million molecular weight polyacrylamide and stir evenly. After 5 hours of precipitation, the precipitate accounts for 1 / 4 of the total liquid volume, namely: 1250 liters, the volume of the supernatant was 3750 liters. The supernatant is concentrated by nanofiltration membrane and nanofiltration. The molecular weight cut-off of the nanofiltration membrane is 100 Daltons. 3000 liters of water passing through the nanofiltration membrane are recycled for recycling, and the volume of the remaining concentrated liquid is 750 liters. Combine the primary sediment and the concentrated solution to obtain 2000 liters, adjust the pH=2 with sulfuric acid, and leave to settle for 4 hours. The upper clear liquid is 800 liters. After siphoning, it is nanofiltered again, and the remaining secondary sediment 1200 liters is added with ...

Abstract

The invention discloses a method for preparing a nutrient phagostimulant by utilizing heparin wastewater. The method comprises the following steps: extracting wastewater generated by heparin by an enzymolysis method; adding a flocculant for precipitating to obtain a primary precipitate and a supernate; performing concentration by nanofiltration on the supernate; recovering and recycling the clean water which passes through a nanofiltration membrane; merging the concentrate and the primary precipitate; adding an acid to adjust the PH to be 2 to 3; performing secondary precipitating; siphoning the supernate; adding a decolorizer into the remaining precipitate for decolorizing; performing vacuum concentration on the decolorized remaining precipitate; adding amino acids and saccharides into the obtained vacuum concentrate for performing a Maillard reaction; spray-drying to obtain the phagostimulant. According to the method, water resource is recovered and utilized; the environment is purified; the economic benefit is improved; the unique stench of small intestines is improved by the prepared phagostimulant; the palatability and the food calling property of pets are enhanced; the phagostimulant is rich in nutrients, and is applied to pet staple food or pet snacks or anthony pig and chicken feed as an additive.

Description

Technical field [0001] The invention relates to a method for treating heparin wastewater, in particular to a method for preparing a nutrient attractant by using heparin wastewater. Background technique [0002] At present, the industry mainly uses enzymatic hydrolysis to produce heparin. The raw material is pig small intestine mucosa. The production process is: fresh pig small intestinal mucosa is added with protease. Under the conditions of pH=8.5-9.0, temperature 50℃, and NaCl salinity, the enzyme Dissolve for 2 to 4 hours, inactivate the enzyme, and filter with an 80-mesh sieve to obtain the filtrate. The filtrate is added with a large-pore cation adsorption resin to adsorb heparin, and then filtered, eluted, precipitated with alcohol, and dried to obtain crude heparin. [0003] In the process of extracting heparin by enzymatic hydrolysis, a large amount of wastewater is generated at three process nodes: 1. Adsorption wastewater is produced after resin adsorption; 2. Elution wa...
