摘 要:通過(guò)對污水處理廠(chǎng)的剩余污泥進(jìn)行厭養培養,獲得硫酸鹽還原菌(SRB)占優(yōu)勢的厭養污泥,利用固定化技術(shù)對富含SRB的污泥進(jìn)行包埋固定,制得SRB固定化小球?疾炝嗽诓煌琾H值、溫度、COD/ SO42-等條件下,SRB固定化小球處理鍍銅、鍍鐵混合電鍍廢水的效果。結果表明:pH值為7,溫度為35℃,COD/SO42-比值為3時(shí),銅、鐵的去除率分別可達到99.9%、98.8%以上。 |

Abstract:Waste sludge from sewage treatment plant was cultivated so as to getting activated sludge containing mainly SRB. The sludge was immobilized in small particles. With immobilized SRB,the particles were used for treating electroplating wastewater containing copper and iron. The removal rate of copper and iron ions were 99.9% and 98.8%, respectively,under the conditions of pH 7,35℃ and the ratio of COD/SO42- at 3. |
Key words:electroplating wastewater;sulfate-reducing bacteria(SRB);waste activated sludge;immobilization technology |
