污水处理的每项工艺技术都有其优点、特点、适用条件和不足之处,不可能以一种工艺代替其他一切工艺,也不宜离开当地的具体条件和我国国情。同样的工艺,在不同的进水和出水条件下,取用不同的设计参数,设备的选型并不是一成不变的。那么选择生物脱硫污水处理工艺有哪些原则呢?
Each process and technology of sewage treatment has its advantages, characteristics, applicable conditions and shortcomings. It is impossible to replace all other processes with one process, and it is not appropriate to leave the specific local conditions and China's national conditions. For the same process, under different conditions of inlet and outlet water and different design parameters, the selection of equipment is not invariable. So what are the principles of biological desulfurization wastewater treatment process?
1、技术合理。技术而成熟,对水质变化适应性强,因为项目所在地污水量昼夜变化大,从而造成水质波动较大,处理工艺应具有较强的适应冲击负荷的能力;出水达标且稳定性高,满足受纳水体对排水水质要求,污泥易于处理。选择的处理工艺应确保出水水质满足我国和地方现行的有关规定,符合环境影响评价报告的要求。
1. The technology is reasonable. The technology is advanced and mature, and has strong adaptability to water quality changes. Because the sewage volume in the project site changes greatly day and night, resulting in large fluctuation of water quality, the treatment process should have strong ability to adapt to the impact load; the effluent meets the standard and has high stability, meeting the requirements of receiving water body for drainage water quality, and sludge is easy to be treated. The selected treatment process should ensure that the effluent quality can meet the current national and local regulations and meet the requirements of environmental impact assessment report.
2、经济节能。基建投资和运行费用低,占地少。
2. Economy and energy saving. Infrastructure investment and operation costs are low, and land occupation is small.
3、易于管理。工艺流程须简捷流畅,以降低工程造价及运行费用,操作管理方便,设备可靠。要求管理简单、运行稳定、维修方便。这对于小城市尤为重要,因为小城市往往技术力量比较薄弱。
3. Easy to manage. The technological process should be simple and smooth to reduce the project cost and operation cost, convenient operation and management, and reliable equipment. It requires simple management, stable operation and convenient maintenance. This is particularly important for small cities, which are often weak in technology.
4、重视环境。总平面布置力求流程顺畅,合理紧凑,减少占地,土方平衡并考虑防洪、预留远期处理用地。厂区平面布置与周围环境相协调,注意厂内噪声控制和臭气的治理,绿化、道路与分期建设结合好。
4. Pay attention to the environment. The general layout should strive for smooth flow, reasonable and compact process, reduce land occupation, balance earthwork, and consider flood control and reserve land for long-term treatment. The layout of the plant area should be coordinated with the surrounding environment. Attention should be paid to the noise control and odor control in the plant. The greening, roads and phased construction should be well combined.
5、采用以生物方法为主体的处理工艺,在生物处理构筑物中,去除大部分的污染物。
5. Most of the pollutants in the biological treatment structures are removed by the biological treatment process.
6、除磷、脱氮效果好,运行稳定。
6. The effect of phosphorus and nitrogen removal is good and the operation is stable.
以上就是对选择污水处理工艺有哪些原则的介绍了,选择污水处理工艺应根据原水水质、出水要求、污水厂规模,污泥处置方法及当地温度、工程地质、征地费用、电价等因素作慎重考虑。希望上述内容对大家有所帮助,如想了解更多内容请点击官网:

The above is the introduction of the principles for the selection of sewage treatment process. The selection of sewage treatment process should be carefully considered according to the raw water quality, effluent requirements, sewage plant scale, sludge disposal method, local temperature, engineering geology, land acquisition cost, electricity price and other factors.
