BIOLOGICAL OXIDATIONAL CONTACT STABILIZING POND

摘要

FIELD: waste water purification. SUBSTANCE: pond of invention contains reservoirs filled layer-to-layer with sand, gravel, and sand with planted higher aqueous vegetation. These reservoirs communicate with tank provided with level switch and pump assembly with control system, electrical motor, and program device. Invention allows purifying waste water during all the year owing to optimal anaerobic purification condition, and also reducing pond area. EFFECT: intensified purification process. 2 dwg
