方形化粪池模具,圆形化粪池模具介绍的主题内容主要在于两种不同形状但是同一模具的差别。方形化粪池模具,圆形化粪池模具介绍是根据目前常规使用的2.3*2m的化粪池预制件而言，在化粪池预制件的生产中，使用方形化粪池模具(也成为八角形化粪池模具)的比较多。尽管圆形的看起来外形美观一些，而且实际操作起来施工也比较便利，但是还是使用方形化粪池预制件的比较多。从根本上说，八角代表了一个造型，而这个造型符合历史文化的需要，而从实际效果来看，方形的在施工、搬运、储存量上都是比较大的。
The main contents of the square septic tank mold and the circular septic tank mold are mainly in two different shapes, but the difference between the same mold. Square septic tank mold, circular septic tank die introduction is in accordance with the conventional use of the 2.3*2m septic tank prefabricate, in the production of septic tank prefabricate, the use of square septic tank mold (also become octagonal septic tank mold) more. Although the round appearance looks beautiful, and the actual operation is convenient, but the use of square septic tank prefabricated parts is more. Fundamentally, the octagonal represents a model, and this model meets the needs of history and culture, and from the actual effect, the square in the construction, handling, storage is relatively large.
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BOD5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，易腐败的生污泥转化为稳定的熟污泥，改变了污泥的结构，降低了污泥的含水率。定期将污泥清掏外运，填埋或用作肥料。要求：化粪池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~24h。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 kind of primary transitional life processing structure, which uses the principle of precipitation and anaerobic fermentation to remove the suspended organic matter in domestic sewage. There are a lot of feces, paper scraps and pathogens in domestic sewage. The solid concentration of suspended solids is 100~350mg/L, and the concentration of organic matter is BOD5 between 100~400mg/L, and the concentration of suspended organic matter is 50~200mg/L. The sewage enters the septic tank after 12~24h precipitation, which can remove 50%~60% suspended solids. The sludge is decomposed through anaerobic fermentation for more than 3 months. The organic matter in the sludge is decomposed into stable inorganic matter, and the corrupted raw sludge is converted to stable ripe sludge. The structure of the sludge is changed and the water content of the sludge is reduced. The sludge should be regularly transported to the landfill or used as fertilizer. Requirements: the sediment volume and the calculated volume of the putrefaction part of the septic tank shall be determined according to the 4.8.4 to 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~24h. For sewage disposal system without sludge disposal, the volume of septic tank should also include the volume of storage sludge.
