| 传统化粪池的应用已经有一百多年历史，技术路线是污水和污泥接触的模式，沉积的污泥消化降解产生沼气、二氧化碳、硫化氢等消化气，消化气的上浮作用对污泥产生扰动，消化气对污泥的扰动作用能够让污泥与生物菌群的混合更充分，有助于消化降解。但底部污泥随消化气上升，气泡逸出后，污泥又重新向下沉淀，这些上升和沉淀的污泥又重新污染污水。 The application of traditional septic tank has a history of more than 100 years. The technical route is the contact mode between sewage and sludge. The digestion and degradation of sedimentary sludge produces digestive gas such as biogas, carbon dioxide and hydrogen sulfide. The floatation of digestive gas disturbs sludge. The disturbance of digestive gas to sludge can make sludge and biological bacteria flora. Mixing more fully helps digestion and degradation. However, the bottom sludge rises with digestion gas, and after the bubbles escape, the sludge is re-deposited downward, which re-pollutes the sewage. 在化粪池污水与污泥接触混合的技术模式下，影响橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子 化粪池的沉淀及出水水质，需要延长污水停留时间来改善沉淀效果及出水水质，污水停留时间一般为12-24小时。 Under the technical mode of contact and mixing of septic tank sewage and sludge, the sedimentation and effluent quality of septic tank are affected. It is necessary to extend the residence time of sewage to improve the sedimentation effect and effluent quality. The residence time of sewage is generally 12-24 hours |
