Due to the severe pollution taken place in Taihu Lake, the investigation of water source quality in Taihu Lake is urgent for the development of drinking water treatment processes. Water samples taken from two water source areas in Taihu Lake were analyzed. The results showed that ammonia, TN, TP and CODMn were the dominant contaminants. The concentrations of those contaminants all exceeded “surface...
In the pilot scale test, three kinds of typical natural solid phase materials, such as cotton, anthracite and walnut shells, were used as biological denitrification carbon sources in the remediation of nitrite contaminated groundwater. The results indicated that when the influent concentration of nitrate was about 30mg/L, the nitrate removal of the reactors with cotton and walnut shells as carbon...
We present a human centric cyber physical framework architecture of our in-pipe water monitoring and feedback system. This system comprises of the physical water distribution infrastructure, together with the hardware and software supported intelligent agents for water allotment, leak detection and contamination spread control. An agent-based approach for connecting the cyber and physical layers is...
There is a globally increasing issue that groundwater contamination by nitrogenous fertilizer in the contemporary world, however as an important water, groundwater always serves, especially in rural region. To address this problem, biological nitrification and denitrification course has been pervalently used for removal of nitrogenous pollutants from polluted groundwater. The dissolved oxygen (DO)...
