Embodiment 1

[0063] Example 1: A compound enzyme preparation that can degrade food waste:

[0064] This example provides a compound enzyme preparation that can degrade food waste, which is specifically prepared by the following method:

[0065] 1) Riboflavin and mercaptobutyric acid are mixed according to the molar ratio of 1:1.4, then 12% of the riboflavin molar weight of magnesium perchlorate and 50% of the riboflavin molar weight of cyclohexane are added, and stirred at room temperature , the stirring rate was 200r / min, and the water was separated by reflux until no more water was generated; the reaction product was washed with distilled water, and then extracted with ether, and the organic phase was extracted with anhydrous MgSO 4 Dry, filter, remove ether, and distill under reduced pressure at 82°C and 1.35kPa to obtain riboflavin ester derivatives;

[0066] 2) 4g enzyme activity is 6000U / g phosphatase, 4g enzyme activity is 12000U / glucose diclease, 5g enzyme activity is 1600U / g papa...

Embodiment 2

[0069] Example 2: Another compound enzyme preparation that can degrade food waste:

[0070] This example provides another compound enzyme preparation that can degrade food waste. Its preparation method is basically the same as that of Example 1, except that in this example, sodium alginate grafted N-(2-aminobenzene Base)-N-phenylthiourea process, the addition amount of sodium alginate, N-(2-aminophenyl)-N-phenylthiourea is respectively 1g, 0.2g, and N-(2-aminophenyl) The grafting ratio of phenyl)-N-phenylthiourea to sodium alginate was 17.2%.

Embodiment 3

[0071] Example 3: Another compound enzyme preparation that can degrade food waste:

[0072] This example provides another compound enzyme preparation that can degrade food waste. Its preparation method is basically the same as Example 1, except that in this example, sodium alginate, N-(2-aminophenyl) The addition amounts of -N-phenylthiourea were 1 g and 0.35 g respectively, and the grafting rate of N-(2-aminophenyl)-N-phenylthiourea to sodium alginate was 24.7%.

Abstract

The invention belongs to the technical field of kitchen waste treatment, and particularly relates to a complex enzyme preparation capable of degrading kitchen waste and a preparation method and application thereof. According to the invention, the complex enzyme preparation is obtained by forming a complex enzyme by a lipolytic enzyme, a cellulose hydrolase and a proteolytic enzyme and carrying out embedding treatment on the complex enzyme by using sodium alginate grafted N-(2-aminophenyl)-N-phenylthiourea and polyvinyl alcohol; macromolecular organic matter in the kitchen waste can be quickly degraded; the defect that the water vapor condition is difficult to control in the kitchen waste fermentation process is avoided; no anaerobic bacteria exist and the degradation effect is avoided; the water vapor condition does not need to be adjusted; odor cannot be generated; organic matter in the waste can be rapidly and efficiently degraded at the normal temperature; the treatment effect is good; degradation products are water and carbon dioxide; and secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment, and in particular relates to a compound enzyme preparation capable of degrading kitchen waste, a preparation method and application thereof. Background technique [0002] Kitchen waste is the domestic waste formed by residents in the process of life. It mainly comes from food processing waste and table leftovers generated by families, canteens, schools and catering industries. With the improvement of people's living standards, there are more and more food waste. . The composition of food waste is relatively complex. It is a mixture of water, oil, vegetables, rice noodles, fish, meat, bones and other substances. It mainly contains organic matter such as fiber, protein, and oil. It has high organic matter content, high moisture content, and is perishable and smelly. , especially in summer, food waste is piled up everywhere, and it will rot and deteriorate in a short period of time,...
