2.2 设计原则
本方案系根据实际废水的特点及业主的要求,在我司成功的业内工程实践及稳定成熟的工艺技术基础上进行设计,总体原则是“经济合理、安全可靠”。主要的细节方面有:
(1) 污水处理工艺根据原水的水质水量、受纳水体的环境容量与利用情况,综合实际,考核比较各经济技术指标,优先采用低能耗、低运行费用、低基础建设费用、占地面积小、操作管理稳定方便的处理工艺。
(2) 积极采用经过实践证明的成熟工艺,使之成为主体工艺;积极慎重地采用经过鉴定的优良新技术、新工艺、新材料和新设备;在可靠的基础上,达到投资和效益的最优化。
(3) 满足用户要求,切合实际条件,美化、绿化地面环境,地上的建构筑物与环境相协调。
(4) 根据现场条件,平面与高程按流程依次布置、减少管线,做到流程畅顺、占地面积小、便于维护,尽量减少提升和水力高程损失。
(5) 以人为本,安全第一,设置安全防护保障措施,加强机械化作业;运行操作以自动化为主、人工控制为辅,设人机监控界面。
(6) 工艺系统可灵活调整。设备运行高效稳定,选用寿命长、质量好的产品。减少剩余污泥产量。
(7) 妥善处置水、气、声、渣,避免二次污染。
