Embodiment 1
[0025] Please refer to the attached figure 1 , 2 and 3.
[0026] The components and contents of the additives of the present invention are verified through two-step experiments. The first step (initial experiment) is to test each component separately. The results show that LAS can effectively inhibit the activity of methane bacteria, enzymes can accelerate the hydrolysis of organic matter, and sodium metasilicate has the strongest ability to adjust the pH value of the system, but The best combination is determined by the following second-step experiment (the purpose of adding sludge to domestic waste is to accelerate methanation):
[0027] Weigh 5.0 g of crushed household garbage (dry weight) and 2.0 g (dry weight) of sludge, and put 7.0 g (dry weight) in total into a 250 mL serum bottle, then add distilled water to adjust the water content to 90%. In order to ensure that the reaction is carried out under anaerobic conditions, 7 parts of 7 kinds of additives containing diff...
Embodiment 2
[0033] Please refer to the attached figure 1 , 4 , 5 and 6.
[0034] Weigh a total of 7.0g of crushed domestic waste and sludge (dry weight, wherein, domestic waste: sludge = 55% to 100%: 0 to 45% by mass), put it into a 250mL serum bottle, and then add distilled water to adjust The water content is 90%, then add 0%, 2.50% ... 10% of 8 kinds of additives of the present invention with different weights of the total amount of domestic garbage and sludge, to ensure that the reaction is carried out under anaerobic conditions, after the feeding is finished, Flush into nitrogen for 30 seconds, drive out the air above the serum bottle (simulating the anaerobic state of domestic waste landfill), collect the gas by draining saturated saline, and measure the components and their contents in the gas by gas chromatography. In the initial stage of the reaction, a small amount of hydrogen gas was detected in the system. As the reaction progressed, the pH dropped sharply (about 5.0), and t...
