What is a feces-urine diversity toilet?

Dry sealed latrines do not need to be flushed with water, which is mainly aimed at the vast rural areas without sewers. The principle is that feces and urine are collected separately, and urine rich in nutrients and basically harmless is directly used as fertilizer after short-term fermentation.
