1, in the human fecal urine added fine dry soil, turf and other highly absorbent substances. Human fecal urine has high nutrient content, rapid decomposition, and rapid fertility, but it is easy to lose. If substances with strong adsorption ability such as dry soil and turf are put into the septic tank as a cover or mixed in excrement, they can be used to absorb urine and Ammonia can greatly reduce nitrogen loss. According to the experiment, adding 25% of fine dry soil to human excreta can reduce nitrogen loss by 10%.
2. Add superphosphate to human waste. Adding 3%-5% of superphosphate to human waste can not only reduce nitrogen loss, but also increase phosphorus and other nutrients in human waste.
3. Add ferrous sulfate to human waste. 250-300 grams of ferrous sulfate is added to every 50 kilograms of human waste, which is both nitrogen and deodorant.
4. Add gypsum powder to human waste. Each 50 kilograms of fresh cow dung is added with 50 grams of soybean flour, placed in a jar and stirred evenly, sealed at 25°C for 3 to 5 days, and diluted with water 3 times when applied.
5. Add superphosphate to the fertilizer. Add 2% of superphosphate to the fertilizer, stir and store for about 20 days. The fertilizer effect can be increased by more than 1 times.
