PHOSPHORUS RECOVERY SYSTEM AND METHOD USING THERMAL EXPENSION SLUDGE DECREASING APPARATUS

摘要

PURPOSE: phosphorus recovery system is when solving the pathogen of safety problem, due to recycling sewage sludge. ;CONSTITUTION: phosphorus recovery system includes: that thermal expansion sludge contracting becomes device (100); Phosphorus recycles basin (200) and thermal expansion sludge contracting becomes device, collects phosphorus from sludge discharge and becomes device from thermal expansion sludge contracting; Chemical power device (300) is connected to the bucket of phosphorus recycling, and controls pH value in chemical phosphorus recovery bucket; The bucket recycled with magnesium material feeder (400) and phosphorus, and the bucket that magnesium material recycles phosphorus. ;The 2013 of copyright KIPO submissions;[Reference numerals] (AA) electric discharge sludge; (BB) electric discharge struvite crystals
