摘要：
An efficient combined treatment process, limeelectrolysis was developed to treat the Ultra-high concentration phosphorus-containing Wastewater. The experimental results show that the removal rates of COD and TP are 86.4%, 69.9%, respectively. The results indicated that the optimal conditions are: lime dosage was 2g, pH 8.5, mixing rate 2.5(equivalent units) and reaction time 20min, sedimentation time 10min; using the soluble iron plate and carbon rod as electrode plate, electrolysis pH 7, electric current 0.4 A, reaction time 80 min, exchange electrode reaction 2min per 12min. The biodegradability of the wastewater was improved evidently. This combined process provides instructive example for efficient treatment of Ultra-high concentration phosphorus-containing Wastewater.
