Embodiment 1

[0016] Put 40 Tenebrio molitors in each petri dish, mix plastic foam and bran at a mass ratio of 1:10, 1:8, 1:6, 1:4 and 1:2 respectively to prepare feed and cultivate under constant temperature and light Tenebrio molitor was raised in the box, and the light control in the constant temperature light incubator was 14L:10D, the relative humidity was 70%, and the temperature was 25°C. Put a small amount of cabbage leaves of equal quality in each petri dish, and spray water appropriately to ensure the humidity. Add a group of blank control, only add bran, each group has 3 repetitions.

[0017] Weigh the quality of Tenebrio molitor and the reduction of plastic foam in each petri dish once every 7 days, and record the number of deaths of Tenebrio molitor in the petri dish, calculate the average weight and average gain of each group, and all weighing data are reserved for 5 days. significant digits.

[0018] Observe the development progress of Tenebrio molitor at 8:00, 15:00, and 22...

Embodiment 2-3

[0040] Referring to Example 1, the process conditions different from Example 1 and related parameters are shown in Table 3.

[0041] The technological parameter of table 3 embodiment 2-3 and related data

[0042]

[0043] The method for degrading the plastic foam of the present invention is to feed the Tenebrio molitor by mixing the plastic foam and bran to prepare feed, and use the Tenebrio molitor to degrade the plastic foam, which is environmentally friendly and economical, and has a simple operation method. The optimal feed ratio of Tenebrio molitor is foam:bran=1:6, that is, when 14.28% foam is added to the feed, the growth status of Tenebrio molitor and the degradation of foam are optimal, which provides a basis for environmental protection. Theoretical data and experimental support, so that when the population of Tenebrio molitor is enlarged by raising a large number of Tenebrio molitor indoors, waste utilization can be realized to the maximum extent, cost can be sav...

Abstract

The invention discloses a degradation method of plastic foam, which comprises the steps that the plastic foam and bran are blended into feed; yellow mealworms are raised in a constant-temperature illumination incubator by using the blended feed; and a mass ratio of the plastic foam to the bran is 1:(2-10). According to the degradation method of the plastic foam, the plastic foam and the bran are mixed and blended into the feed for raising the yellow mealworms, and the plastic foam is degraded by the yellow mealworms, so that the degradation method is environment-friendly, economical, and simple to operate.

Description

technical field [0001] The invention relates to a method for degrading plastic foam. Background technique [0002] Plastic foam is a chemical material, its full name is Expanded Polystyrene (EPS), which has the characteristics of light weight, firmness, shock absorption, low humidity, easy molding, good water resistance, heat insulation, and low price. It is widely used in packaging, heat preservation, waterproof, heat insulation, shock absorption and other fields, and is one of the most widely used plastics in the world today. At present, plastic foam fast tableware is used more in our country. A large number of discarded plastic foam fast tableware are scattered along the traffic, rivers and lakes, tourist attractions, streets and alleys, forming the well-known "white pollution". Plastic foam is not easy to rot in nature, and it is not easy to be degraded by microorganisms. Even if it is buried deeply, it will pollute groundwater sources, destroy the soil structure, and r...
