城镇沼气化粪池(以下简称沼气池),包括城镇公厕沼气化粪池、机关办公楼沼气化粪池、单元式宿舍沼气化粪池等。一、修建单元式宿舍沼气池有哪些新问题 1.宿舍大都是室内标高同室外标高差距较小,一般约15—30厘米,宿舍厕所安置大便器、盛水弯管,约距地面标高-30至-50厘米,即厕所内大便器排污水管在室内标高约-50厘米,室外标高-30厘米左右,而粪便污水管埋置深度,一般都在室外标高-1.2米以上,修建沼气池就带来了新问题,进料管口较低。 2.单元式宿舍的生活污水与粪便污水,一般是两根落水管通地,连接阴井,汇合于一根污水管排入下水道,即粪便、生活污水都进入沼气池内,粪少水多,对沼气发酵和除害灭病都不够理想,直接影响效益,同时,也不经济。
Urban biogas septic tank (hereinafter referred to as biogas digesters), including urban public toilets biogas septic tank, office building biogas septic tank, unitary dormitory biogas septic tank. First, the construction of modular dormitory digester What are the new problems 1 dormitory are mostly indoor elevation with outdoor elevation difference is small, usually about 15-30 cm, dormitory toilet stools, water pipe, about 30 degrees above ground level To -50 cm, that toilet toilet sewage pipe in the indoor elevation of about -50 cm, outdoor elevation of about -30 cm, while the depth of manure sewer pipe embankment, usually in the outdoor elevation of -1.2 meters, the construction of digesters on the band A new problem, the feed orifice is low. 2. Unit dormitory sewage and manure sewage, usually two through the ground, connected Yin wells, confluence in a sewage pipe into the sewer, that is, manure, domestic sewage into the digester, less manure less water on the Biogas fermentation and pest elimination are not ideal, a direct impact on efficiency, at the same time, not economical.
