Three-form septic tank

一体化滚塑三格式化粪池
基本结构和原理：
1、沉淀腐化区对生活污水进行沉淀，比重大的物质沉入池底进行化粪处理，比重小的部分浮于水面上层，可从清理口捞出，同时废水产生划粪作用，使一部分结构复杂的难分解的有机物被降解为易分解的物质。
2、隔板区
将直流水转成环流水，增加污水在池体内的滞留时间，使污水在池内与沉淀污泥的接触时间更长，产生更多的微生物，对污水进行分
解吞食。
3、过滤器处理区
采用国内外先进的生物膜法处理技术，经过一定时间培育，大量微生物在过滤器表面繁殖形成生物膜，污水与过滤器表面的生物膜接触，有机物被微生物截留，吸附和分解，实现对污水净化处理。
主要特点：
1、容积 1.0-1.5m3，符合《Q/SWY011-2015三格式化粪池》标准。三格容积的分配比例 2∶1∶3
2、优化结构设计，工艺技术成熟，产品强度高，耐酸碱，防腐蚀。
3、滚塑一次成型，无需两体对接，解决渗漏的问题。
4、省工，省时，使用寿命可达 5 0 年以上。

Installation instructions:

1. Dig a cuboid pit with a length of 2 meters, a width of 1.4 meters and a depth of 1.2 meters, and use 50mm concrete as a cushion layer.

2. Put the three-cell septic tank flat, connect the chemical manure pipe and exhaust pipe, and the exhaust pipe should be 20-50cm higher than the toilet house.

3. The backfill soil should be semi-dry and semi-wet, tamped layer by layer, and backfilled layer by layer until the ground is level to prevent the collapse and tilt of the urn body. The filling should be carried out in two phases: the first backfill half to a depth of 0.6m, sprinkle a small amount of water to tamp and level, and then fill the soil twice to the surface level. The top three outlets are 5-10 centimeters higher than the ground, and cement mortar is used around the outlet cover to strengthen the seepage prevention and fixation.

4. The bedpan should be parallel around the installation, and the vertical should be high before and low after the longitudinal (5° inclination) to ensure that the bedpan does not leave water after flushing. The distance between the back end of the bedpan and the wall should be between 20-25cm, and the external insulation layer should be added to the bedpan in cold areas. The squat toilet around the first with fine sand, and then with 2 cm cement mortar leveling.

5, the installation of water storage barrel water pipe to ensure natural placement, not S-shaped laying, to prevent water icing. The water storage bucket should be placed behind the bedpan. When installing the indoor water storage bucket, the bucket cover is 10 cm lower than the ground. The bucket cover can be covered with thermal insulation materials. When backfilling, the water storage bucket should be filled with water first, and then filled with earth and tamped.
