Neutral test on the utilization of ceramic UF in circulating cooling wastewater in coalfired power plant

Abstract

Abstract:

Circulating cooling wastewater is one of the main sources of industrial wastewater of coalfired power plant. Its recycling process and equipment have been popular in wastewater zero discharge study in recent years.Taking the circulating cooling wastewater of Huadian Tengzhou Xinyuan Thermal Power Company Limited, neutral test is carried out with softened clarifiers and ceramic ultrafiltration equipment under specific operating parameters and conditions.The accumulated data prove that cooling wastewater softened and clarified by equipment with ceramic UF membrane, can keep its flux at 260L/(m2·h)stably.The chemical maintenance cleaning cycle is 12 hours.The turbidity of permeate should be less than 0.2 NTU and SDI should be less than 3.The effluent completely meet the requirements of reverse osmosis.The ceramic UF system can work well with high operating flux,operational stability and good water quality.
