Septic tanks effectively address the issue of domestic wastewater discharge in rural areas, ensuring people's living standards while also preventing wastewater from impacting local water sources. Without septic tanks for preliminary treatment, domestic wastewater would directly enter sewers or outdoors, causing severe environmental pollution and potentially spreading diseases. Septic tanks preprocess wastewater before discharge, reducing water body pollution and the environmental burden.

Operating Principle and Function:
Septic tanks are basic sludge treatment facilities and also pre-treatment facilities for domestic wastewater, serving the following functions:
1. Ensure the cleanliness of residential community environments, preventing the spread of domestic wastewater and pollutants.
2. Eliminate mosquito and fly larvae in the anaerobic digestion environment of septic tanks.
3. Temporary storage of sludge, anaerobic digestion of organic sludge, and matured organic sludge can be used as agricultural fertilizer.
4. Pretreatment of domestic wastewater (primary treatment), sedimentation of impurities, and hydrolysis of macromolecular organic matter into smaller molecules like acids and alcohols, to improve subsequent wastewater treatment.
