源分离农村卫生厕所冲水灌溉利用技术研究

针对现在我国农村缺少有机肥源,而普通厕所又将人类粪便冲走变成污染物造成环境污染与资源浪费的情况,提出了将源分离农村卫生厕所与农田滴灌利用技术结合的解决方案,通过源分离的农村卫生厕所将人类排泄物分离成大便冲水及小便冲水,小便冲水通过管道分流到储存池中,待尿液中的尿素转变成可利用的氨氮后通过滴灌系统对农田进行滴灌.通过这种利用模式,不仅能解决农村人类排泄物造成的环境污染,同时又能降低冲水利用量从而节约水资源,还能将排泄物中的氮、磷、钾等营养物质循环利用,形成作物-人体-作物的闭合循环.

The Irrigation Technology of Source-separated in Rural＇s Ecological Toilet

According to the situation that rural lacks of source of organic fertilizer,and we wash away human＇ s stool and urine which would be turned into sewage and costs big bucks to deal with,transform the rural toilet and separate the stool from urine through excrement separating means was proposed.In this system,the stool flushing flowed into the digesters or fertilizer tanks.The urine flushing was collected and transported to the farmer＇ s fields for trickle irrigation through the rational pipeline design,making the effective use of organic fertilizer.This paper focused on the transformation method of rural toilet and the agricultural irrigation technology of urine flushing water,including the combining technology of toilet excrement separator and pipeline,slight disposal technology of urine flush water,the irrigation technology by using solar energy and electric energy mixed,the automatic control technology of trickle irrigation switch.
