AI Technical Summary
Existing septic tank wastewater treatment systems suffer from low sludge activity, insufficient nitrogen removal capacity, and a lack of sludge recycling and synergistic control mechanisms among multi-stage reaction units, resulting in limited system operating efficiency and stability.
The system comprises a hierarchical anaerobic reaction unit, a sludge co-degradation unit, a micro-aerobic enhanced reaction unit, and a deep purification unit. By setting up a hydrolysis acidification zone, an acid production zone, a methanogenic zone, a sludge activation reaction space, a bio-attached filter layer, an ion exchange adsorption layer, and a carbon source release layer, it achieves sludge recycling activation and multi-stage co-treatment.
It improved sludge degradation efficiency, enhanced nitrogen removal capacity, and improved system operational stability and purification effect.
