玻璃钢化粪池发展至今，外形一般为卧式圆筒状，两端封头一般采用力学性能凹凸状面设计，内部设有隔板，隔板上的孔上下错位，不易形成短流，并将整下罐体分成三部分；三级厌氧室、二级厌氧室和澄清室，一级、二级厌氧室底部相通，内部加有“MDS专用特型填料”。这样的分隔减少了污水与污泥的接触时间，使酸性发酵和碱性发酵两个过程互不干扰，同时填料的存在增加了污水污泥与厌氧菌的接触表面积，大大提高了反应效率。它在截流、沉淀污水中的大颗粒杂质、防止污水管道堵塞、减少管道埋深上起着积极作用。
Glass fiber reinforced plastic septic tanks development so far, generally for the horizontal cylinder shape, mechanical properties of commonly used on both ends of the head design of concave and convex shape face, with internal baffle, baffle hole on the up and down, not easy to form a short flow, and the entire tank is divided into three parts; The third level anaerobic chamber, secondary anaerobic chamber and clarifying room, the bottom of the primary and secondary anaerobic Chambers are interlinked, and the internal addition has "MDS special special packing". Such space to reduce the contact time of sewage and sludge, ferment acid and alkaline fermentation process of two mutual interference, at the same time, the existence of packing increased contact surface area of sewage sludge and anaerobic bacteria, greatly improve the reaction efficiency. It plays an active role in intercepting large particle impurities in sewage, preventing the blockage of sewage pipes and reducing the depth of pipelines.
