The outer shell of the rotomolding septic tank is made by the one-time rotomolding process. The rotomolding products are seamless, integrally sealed, leak-free, high in strength, impact-resistant, compressive. The septic tank made of high-density polyethylene has acid alkali resistance, corrosion resistance, light weight durability, simple convenient installation, economical practical, good sewage treatment effect long service life.
Rotomolding septic tank is a basic sludge treatment facility as well as a pretreatment facility for domestic sewage. Its functions are as follows:
1. Ensure the environmental sanitation of the living community avoid the spread of domestic sewage pollutants in the living environment.
2. Kill mosquitoes, flies, eggs in the anaerobic environment of septic tanks.
3. Temporary storage of sludge, organic sludge undergoes anaerobic decomposition, matured organic sludge can be used as agricultural fertilizer.
4. Pretreatment of domestic sewage (primary treatment), precipitation of impurities, hydrolysis of macromolecular organics into small molecular organics such as acids alcohols to improve subsequent sewage treatment.
