Work And Life

Nowadays, with the sustainable economic development in China, the management of the urban constructional planning in various cities in China has also made great progress and improvement, and urban infrastructure construction is also constantly being improved. To make people’s work and life more convenient, municipal projects are also increasing. Municipal water supply and drainage engineering construction in cities are indispensable in urban infrastructure construction. Long-distance drainage often occurs in the construction of water supply and drainage. In order to solve this situation, relevant staff have specially developed a series of long-distance pipe jacking technology and applied it to the construction of municipal water supply and drainage projects, which greatly improves the quality and the efficiency of municipal water supply and drainage projects.

Odour Concentration

Abstract During August, 1983 geosmin was identified in a municipal water supply drawn from western Lake Ontario. The geosmin concentrations were 0.01-0.07 μg L-1, within the range for threshold odour concentration of 0.01-0.2 μg L-1. 2-Methylisoborneol was not detected. The odour 'event' coincided with a dieoff of Cladophora in the lake, but we were not able to establish a direct link between the dieoff and geosmin production. Decomposing Cladophora in shoreline areas produced a strong odour in the air. 3-Methylindole, elemental sulfur, dimethyl tetrasulfide, and dimethyl pentasulfide were tentatively identified in water samples collected from these areas, but geosmin and 2-methylisoborneol were not detected.
