冲洗

The city's reclaimed water treatment plant's filters are periodically cleaned by backwashing.

城市污水处理厂的再生水的过滤器是由定期冲洗干净。

An analysis is made with the emphasis on the evenness and reliability of air and water distribution of the water distribution system in the air/water backwashing filter.

在水处理工艺中，过滤是保证水质的最重要措施，而反冲洗是使滤池得以恢复过滤能力的最关键环节，其配水系统则是核心部位。

The main content of filtration theory of grainy filtering media consists of filtration mechanism,filtration equation and backwashing mechanism.

粒状滤料过滤理论的主要内容是过滤机理、过滤方程式和反冲洗机理。

Thereby, the operation duration is prolonged, and the backwashing frequency decreases.

结果表明，采用周期性排除厌氧富磷液的方法，可有效减缓生物膜中磷的积累，从而延长了反应器的运行周期，降低了反冲洗频率。

BAF backwashing and influent control were the important operational factors for upgrading BAF performance.

曝气生物滤池的进水条件控制和反冲洗是反应器运行特性研究中的主要课题，也是提高反应器处理效率的关键。

For the same reasons, the backwashing concerns the whole surface of the filter, without dead zones; therefore filtration is always carried out on the full surface of the filters.

基于同样的原因，反冲洗涉及到整个滤池的表面，无死区，因此过滤总是在滤池的整个表面进行。

System provide protection devices and monitoring instruments, and also have backwashing function ,will remove dirt and other pollutants, small consumption, automatic operation .

系统配置完善的保护装置和监测仪表，且具有反冲洗功能，泥垢等污染物很快被冲走，耗水量少，具全自动功能。

The factors of dissolved oxygen concentration, hydraulic retention time, nutrient, pH value, temperature and backwashing cycle, which affected the treatment efficiency of spent caustic wastewater were investigated.

研究了溶解氧质量浓度、水力停留时间、营养物质、pH值、温度和反冲洗周期等因素对碱渣废水生物处理效果的影响。

Two forces during the backwashing, the sheer stress of water and the frictional stress between the particles of media, were studied and compared with the adhesion of biofilm.

研究了反冲洗过程中的两种颗粒脱附力：水流剪切力和颗粒间摩擦力，并将它们同颗粒附着力进行了比较。

The wastewater was treated by the CBAF process under optimal conditions: hydraulic retention time of 100 min, dissolved oxygen concentration of about 3 mg·L-1 and the backwashing cycle of every 2—3 days.

CBAF工艺净化该废水适宜的操作条件为：水力停留时间100 min，溶解氧浓度3 mg·L-1左右，反冲洗周期2～3 d。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
