二沉污泥

国内外对污泥厌氧水解产酸的研究多集中于使用初沉污泥或初沉和二沉污泥的混合污泥。

The studies on the fermentation of sludge in the literature mainly focus on the treatment of the primary or its mixture with excessive sludge .

本文根据现场测定和对生物相的观察，指出某市污水净化厂二沉池污泥上浮的原因和解决办法。

Based on the results of onthespot test and investigation of the biological spectrum in a city sewage plant , the paper analyzes the causes and solutions of the rising sludge in the secondary settling pond .

NP的迁出与去除途径包括：初沉池生污泥和二沉池活性污泥的吸附作用，曝气池内的生物降解作用以及随处理出水的排放。

The NP transference ways and removal routes from wastewater treatment system include the adsorption by the primary sedimentation sludge and the activated sludge of secondary sedimentation tank , the biodegradation in aerated tank , and the discharge with the effluent .

为降低能耗，减少基建投资和便于运行管理，本工程还采用了钟氏沉砂池、微孔曝气器、周边进水周边出水二沉池、污泥气浮浓缩池等新技术。

This project also introduces some new technologies to lower power consumption and construction cost .

另外，二沉池的污泥回流依靠动力回流，增加了基建和运行费用。

And ( iv ) the backflow of sludge and nitrified water from the sedimentation tank relies on dynamic system , which increase the cost of construction and operation .

二沉池作为活性污泥系统中一个必不可少的构筑物，在污水处理过程中发挥着重要作用。

As a necessary unit in activated sludge system , secondary clarifier plays an important role in sewage treatment process .

同时，把二沉池排出的污泥回流至水解酸化池进行污泥减容化，还可以降低污泥的处理成本。

Simultaneously , the excess activated sludge that drained from the sediment pool returned the hydrolysis - acidification pool could be degraded , so the treatment cost of sludge could be lower .

模型描述了污泥的浓缩和贮存过程，可用于模拟二沉池中的污泥沿池深方向的分布和底流污泥浓度随运行条件的动态变化。

The model , which describes the sludge thickening and storage processes in a secondary clarifier , can simulate the time variation of the sludge concentration distribution over the tank depth and the underflow sludge concentration .
