化粪池（huàfènchí）是处理粪便并加以过滤沉淀的设备。其原理是固化物在池底分解，上层的水化物体，进入管道流走，防止了管道堵塞，给固化物体（粪便等垃圾）有充足的时间水解。 化粪池（septic tank）指的是将生活污水分格沉淀，及对污泥进行厌氧消化的小型处理构筑物。[3]
Septic tanks (hu à f è nch í) are equipment that processes feces and filters them for sedimentation. The principle is that the solidified material decomposes at the bottom of the pool, and the hydrated material in the upper layer enters the pipeline to flow away, preventing pipeline blockage and giving the solidified material (feces and other garbage) sufficient time to hydrolyze. Septic tank refers to a small treatment structure that separates and settles domestic sewage, and performs anaerobic digestion on sludge. [3]
生活中污水对环境污染日益严重，该产品在总结引进国外生活污水处理工艺的基础上，结合科研成果和工程实践，采用高分子复合材料，工厂化生产，是一种高效、节能、质轻、价廉的生活污水处理设备。它成功替代了传统砖砌和钢混化粪池因渗漏、运行工况不佳而污染地下水质和影响周围建筑物的安全。该产品利用水的重力流，不需任何外来动力和运行费用，节省能源、管理方便。具有很好的社会效益、环保效益和经济效益。
The environmental pollution caused by sewage in daily life is becoming increasingly serious. Based on the summary and introduction of foreign domestic sewage treatment processes, combined with scientific research achievements and engineering practice, this product uses polymer composite materials and is produced in a factory. It is an efficient, energy-saving, lightweight, and cost-effective domestic sewage treatment equipment. It has successfully replaced traditional brick and steel mixed septic tanks that pollute groundwater quality and affect the safety of surrounding buildings due to leakage and poor operating conditions. This product utilizes the gravity flow of water without any external power or operating costs, saving energy and facilitating management. It has good social, environmental, and economic benefits.
