高氨氮中水回用至电厂循环冷却水藻类的控制

Control of Algae in the Power Plant Circulating Cooling Water from Reclaimed Water with High Ammonia

新疆某发电有限责任公司循环水补充水为乌鲁木齐城市中水,该中水从污水处理厂经过石灰软化简单处理后,直接补入循环水塔池。中水COD、氨氮含量高,循环水细菌藻类滋生严重,通过筛选适合杀菌剂和制定严格投加方案后,循环水中细菌藻类的滋生得到控制,机组凝汽器内微生物黏泥量控制理想。

The circulating make - up water of some Xinjiang power plant was Urumqi reclaimed water. The reclaimed water from sewage plant was simply handled by lime softening, then directly added to the circulation water tower basin.The content of COD and ammonia in the reclaimed water were very high, so the bacteria and algae can rapidly grow. After choosing right bactericide and planning strict dosing program, the growth of the bacteria and algae in the circulating water was controlled, and the microorganism mud weight in the unit condenser was controlled ideally.
