The present invention utilizes dibromodimethylhydantoin and adds solubilization agent and disintegrating agent to make them into composition, and makes said composition into disinfectant tablet and disinfectant powder, so that the solubility of dibromodimethylhydantoin can be greatly raised, and its dissolving speed is quick. The above-mentioned disinfectant tablet or disinfectant powder can be dissolved in the water, and can be made into disinfectant liquor, and can be used. Its use concentration is effective bromine content 1-3000 mg / L, and its bacteriocidal effect is obviously higher than that of chlorine-containing disinfectant. It is high-efficiency, broad-spectrum, safe, low-toxic and good in stability.

The invention provides a device and a method for producing biodiesel with illegal cooking oil and waste engine oil. The device comprises an illegal cooking oil settling tank, a waste engine oil settling tank, a mixer, a heat exchanger, a tower-type fixed bed reactor, a condensing system, a gas storage tank, a diesel tank and a gasoline tank, wherein the mixer is connected with the heat exchanger; the heat exchanger is connected with the lower part of the tower-type fixed bed reactor through a preheater; and the condensing system is connected with the heat exchanger. The method comprises the following steps: pretreating, performing catalytic cracking reaction and collecting a product. The produced biodiesel is light yellow in color, has the condensing point of about minus 5 DEG C, has good low temperature fluidity, has a heat value far higher than that of the conventional biodiesel, and has stable product quality; environment pollution is reduced, and a decoloring step is not required; the tower-type fixed bed reactor is applied to the catalytic cracking reaction, so that the method has the advantages of convenience in heating, small investment, easiness in control of treatment amount and low operating cost; and a catalyst can be recycled, so that the device and the method are suitable to be popularized and applied.

The invention discloses a method for storing ginger without using pesticide. The method comprises the following steps of: removing sludge from the gingers and broken gingers; placing the gingers under the blazing sun for quite a long time until ginger epidermis is chapped and dried; cleaning a cellar neatly; performing sterilization and relative humidity control; placing the gingers into the cellar to pile up in a layered way, so that certain gaps are reserved among ginger blocks and the occupied area of the gingers is 3 / 4 to 5 / 6 of the cellar area; sterilizing yellow earth or fine sand; covering the yellow earth or the fine sand on the upper part of the whole ginger pile, wherein the periphery of the ginger pile is exposed; placing dried Chinese mugwort leaves and dried chillies on the open space of the cellar and burning the dried Chinese mugwort leaves and the dried chillies; and when the burned smoke ascends to the cellar opening, sealing the cellar opening, wherein the smoke generated by combustion of the dried Chinese mugwort leaves and the dried chillies has strong pungent smell and can poison ginger maggots in the gingers or the cellar, and the effective rate can reach over 97.5 percent, so that the gingers are prevented from being bitten by the ginger maggots, no decay spots or bugbite spots can be seen from the gingers, and quality of the gingers is guaranteed.
