北方寒区村镇中小型污水厂运行问题及管理措施

Operation Problems and Management Measures of Small and Medium-Sized Sewage Plants in Villages and Towns in Northern Cold Regions

我国北方地区由于其特定的地理位置,冬季气温寒冷,冬季受气温影响中小型污水厂在运行工作中,水处理效果尚不理想。本文通过对北方部分地区村镇级中小型污水厂的实地调研,归纳总结了现有中小型污水厂应用工艺技术的优缺点及适用性,并提出了中小型污水处理厂在冬季运行上的管理措施及建议,从而有效保障中小型污水厂在冬季的水质达标排放。本研究对北方寒区村镇级中小型污水厂的运行管理具有较强的参考价值。

Due to its specific geographical location,the northern part of China has cold temperatures in winter.Affected by the temperature in winter,the water treatment effect is not ideal in the operation of small and mediumsized sewage plants.This paper summarizes the advantages,disadvantages and applicability of the existing technology of small and medium-sized sewage treatment plants through field investigations on small and medium-sized sewage plants at the village and town level in some northern areas,and puts forward management measures for the operation of small and medium-sized sewage treatment plants in winter,and suggestions,so as to effectively ensure the water quality discharge of small and medium-sized sewage plants in winter.This study has a strong reference value for the operation and management of small and medium-sized sewage plants at the village and town level in the northern cold region.
