邢台市污水厂交替式活性污泥处理工艺设计

邢台市污水处理厂在总结一期工程采用土地处理工艺存在的占地面积大、管理不便等主要因素的基础上,二期工程采用了占地少、投资省、运转灵活的交替式活性污泥处理工艺。该工艺不仅吸收了SBR工艺的主要技术特点,还可以像传统活性污泥法那样在恒定水位下连续运行。该工艺将多个单元工艺池巧妙地组合,构成一体化的池组,并采用先进、可靠的高度自控系统实现污水生物法处理。

Design of alternat ing act ivated sludg e pr ocess techniquefor Xingtai w astew ater tr eatment plant

During the first phase of Xingtai wastewater treatment plant land treatment process has the pitfalls of large land area usage and inconvenient management.For this reason,the second phase adopted alternating activated sludge process,which is characterized by small land area,less investment,and flexible operation mode.This process not only has the main process characteristic of SBR process but also can continuously run under invariable water level,like traditional activated sludge process.It combined several process cells into one integrative cell where advanced reliable auto-control system was applied.
