化粪池是一种利用沉淀和厌氧发酵的原理,去除生活污水中悬浮性有机物的处理设施,
属于初级的过渡性生活处理构筑物。生活污水中含有大量粪便、纸屑、病原虫...悬浮物固体浓度为 100~350mg/L,有机物浓度CODCr
在100~400mg/L之间,其中悬浮性的有机物浓度BOD5为50~200mg/L。污水进入化粪池经过12~24h的沉淀,可去除50%~60%的悬浮物。沉淀下来的污泥经过3个月以上的厌氧发酵分解,使污泥中的有机物分解成稳定的无机物

的沉淀部分和腐化部分的计算容积,应按《建筑给水排水设计规范》(GB50015-2003)第4.8.4~4.8.7条确定。污水在化粪池中停留时间宜采用12h~36h。对于无污泥处置的污水处理系统,化粪池容积还应包括贮存污泥的容积。
The septic tank is a treatment facility for removing suspended organic
matter from domestic sewage by using the principles of sedimentation and
anaerobic fermentation. It belongs to the primary transitional life
treatment structure. Domestic sewage contains a large number of feces,
paper scraps, pathogens.... The solid concentration of suspended matter
is 100-350 mg/L, the organic concentration of CODCr is 100-400 mg/L, and
the suspended organic concentration of BOD5 is 50-200 mg/L. Sewage
entering septic tank can remove 50%~60% of suspended solids after 12~24
hours of precipitation. Sedimented sludge is decomposed by anaerobic
fermentation for more than three months, which makes the organic matter
in sludge decompose into stable inorganic matter. The easily corrupted
raw sludge is transformed into stable mature sludge, which changes the
structure of sludge and reduces the water content of sludge. Sludge is
regularly removed and transported, landfilled or used as fertilizer.
Requirements: The calculated volumes of sediment and decay parts of
septic tanks should be determined in accordance with Article 4.8.4-4.8.7
of the Code for Design of Building Water Supply and Drainage
(GB50015-2003). The residence time of sewage in septic tank should be
12h~36h. For sewage treatment systems without sludge disposal, the
volume of septic tank should also include the volume of stored sludge
