Description

technical field

[0001] The invention relates to a device for separating urine and a method for separating urine by using the same. Background technique

[0002] In urban sewage treatment, about 80% of nitrogen and 50% of phosphorus come from human urine, and nitrogen and phosphorus in human urine are the main elements that cause water pollution and eutrophication. In the traditional sewage treatment process, to achieve the harmless treatment of nitrogen and phosphorus, it often requires a long hydraulic retention time and sludge retention time, which undoubtedly increases the cost and efficiency of urban sewage treatment. Urine only accounts for about 1% of the total amount of urban sewage, so it is a future development trend to separately collect, process and recycle human urine.

[0003] For domestic small towns, especially in rural areas, the efficiency of sewage treatment after unified collection is not ideal, and the sewage pipeline facilities are not perfect, or are i...
