aeration period

It is of important to provide a suitable environment for the growth of thermophilic microorganism, during the first period of the static composting process, add to the aeration rate and the turning frequency to increase active microorganism and improve the quality of composting product.

建议在静态一次堆肥发酵周期中，增加通气量和翻堆频率，有利于增强微生物菌群的活力和提高堆肥质量。

The pre-filmed treatment by aeration on PAC could improve the process of sludge granulated in the UASB reactor. The start-up period could be shorten to 49 d from 57 d.

PAC经过好氧预挂膜处理后，可加快UASB中污泥颗粒化进程，UASB的启动时间由57天缩短为49天；

Unlimit aeration style had good tolerance to shock loads, its oxygen demand was even, and it could reduce the reaction period;

非限制曝气方式耐冲击负荷，需氧均匀，能缩短反应周期；

In the system of SBR following biological hydrolysis reactor, the aeration period should exceed 6.5 hours.

工程设计中，在水解酸化反应器后应加设沉淀单元。在SBR好氧生物处理系统中，曝气反应时间宜大于6.5小时。
