Sludge Volume Index

The change of sludge volume index ( SVI ) .

污泥容积指数SVI的变化情况。

And the sludge volume index ( SVI ) increase , settling property enhance , p content in sludge increase .

且污泥容积指数SVI增加，沉降性能增强。污泥含磷量越大。

Meanwhile , the sludge volume index would also increase with the increasing of influent flow distribution coefficient .

同时污泥体积指数也会随着进水流量分配系数的升高而增大。

An approach to relating the settling property parameters to the sludge volume index SVI is also presented .

并提出采用与SVI的相关性确定模型中表示污泥沉降性能的参数。

Two methods determining the sludge volume index under diluting sludge concentration and practical sludge concentration are analysed and compared .

同时，对在稀释浓度和实际浓度条件下测定污泥指数的两种方法进行了分析比较。

The Influences of SVI ( Sludge Volume Index ) on Purification of the Sewage in the Debugging and Running of SBR ( Sequencing Batch Reactor ) Technology

序批式反应器工艺调试运行中污泥指数对净化污水的影响

Treated by NaOH , extracellular polymeric substances ( EPS ) on microbial cells was released , sludge volume index ( SVI ) was reduced while the supernatant TOC was increased .

投加碱液使污泥胞外多聚物（EPS）减少，污泥容积指数（SVI）降低，但上清液中总有机碳（TOC）浓度增加。

Furthermore , the microbe ecology system of the UFTR reactor is more stable , the sludge volume index ( SVI ) of the UFTR system was lower , and the stability of the sludge in the UFTR system was higher .

而且UFTR反应器所形成的微生物生态系统更稳定，污泥指数较低，污泥的稳定性较好。

The nitrifying granules were dense when the heterotrophy granules disaggregated on day 160 . The value of sludge volume index ( SVI ) was below 20 ml / g and the mean granules size was about 1.2 mm .

试验运行至第160天时，异养颗粒污泥破裂解体时，硝化颗粒污泥仍结构致密，没有破裂现象发生，SVI值保持在20ml／g以下，颗粒粒径在1.2mm左右。

The relation between sludge load and sludge volume index

污泥负荷与污泥容积指数的关系研究

With the increase of proportion of the irradiated sludge , SVI ( sludge volume index ) of the sludge in the US-SBR increased continuously , but it had little influence when the proportion of the irradiated sludge was no more than 10 % .

随着超声处理污泥比例的增加，污泥体积指数SVI持续增大，但是超声污泥比例不超过10%对污泥沉降性能影响不大。

The results showed that the sludge settling performance improved and sludge volume index ( SVI ) decreased with the increase of salinity .

结果表明，盐度对污泥沉降性能的影响比较明显，盐度有利于污泥沉降。随着盐度的提高，污泥的沉降性能越来越好，污泥容积指数逐渐降低，污泥出现膨胀的SVI临界点显著降低。
