| Abstract | In order to investigate the effect of vermiculite with gravel on road runoff, we research the removal efficiency of road runoff pollutant with the combination of different sizes of gravel with vermiculite, through the indoor simulation experiment. The road runoff pollutant indexes include potential of hydrogen (pH), suspended solids (SS), biochemical oxygen demand after 5 days (BOD5), chemical oxygen demand (COD), petroleum and heavy metals (including Cu, Zn and Pb). The results show that the combined decontamination materials have the effect of adjusting pH, the removal rate of suspended solids is from 25.00% to 92.31%, heavy metals' removal rate is30.51% to 70.50%, the removal rate of COD is 20.43% to 60.10%, the removal rate of BOD5 is 20.00% to 60.00%, the removal rate of petroleum is 33.85% to 77.85%.For the same kind of vermiculite, after the treatment of sewage with the combination, the concentration of each combination of pollutants shows gradual downtrend with the decrease of gravel sizes, but the removal rate of accumulation of pollutants increases gradually. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
