摘　　要：宁波市梅林水厂生物预处理工艺已完成了设计、施工 .生物接触氧化池是在原斜管澄清池的基础上改造而成的 ,日处理能力 4万m3·d- 1 .生物接触氧化池的曝气方式采用水气逆向流曝气 ,曝气器采用膜片式微孔曝气器 ,填料采用半软性弹性立体填料 .对该工艺的设计作了较全面的介绍 。Design and construction of biological pretreatment technology of Meilin Waterworks in Ningbo City have been accomplished. The bio-contact oxidation pool has been built on the base of the sloped tube clarifier tank in the waterworks. The bio-contact oxidation pool can treat 40 000 m 3·d -1 of raw water. The semiflexible elastic cubic packing material has been chosen as the packing material of the oxidation pool. The aeration method, in which air flow is in the opposite direction to the water, is adopted in the technology. The aerator is a micropore aerator with rubber diaphragm. The paper introduces the design of the processing technology in details and discusses some problems of the design.
