参观南京城北水厂(国外英文资料) Visit the north water factory in nanjing In early July, we went to visit the north water plant in nanjing to learn about the process of water treatment. The water plant is composed of two spread a diameter of 2400 in the tunnel of underground pipes from primary pump room will be muddy water from the river to the water treatment works, the total length of 700 meters, second only to xuanwu tunnel, tunnel is north of the source water. The first phase of the water plant in chengbei water supply is 500,000 tons per day, and the water supply is 250,000 tons. The construction was built in April, 1997, and the construction was completed in August 2000. That compared with the north river water, higher degree of automation, the source water of 23.5 mu, none of T area, the water treatment works fully controlled by computer, testing probe, the microcomputer system of central control room monitoring source waterworks work 24 hours a day. And north water pump unit also introduces the high voltage variable frequency speed regulating device, high speed frequency, low energy consumption, energy saving of eighteen percent, can also save electricity for the whole year is about 2.5 million yuan. After the construction of the water diversion project and the water pipeline, the land has been restored and greening. Engineering USES the tubular static mixer, flocculation with hydraulic, vertical flow folded-plate flocculating process, precipitation by advection sedimentation tank, v-shaped filter and supporting facilities such as water, but not construction production wastewater sludge concentrating and dewatering device, sewage and rainwater discharged into municipal network, also the main noise source acoustic noise reduction measures were taken. Campus green area of 8800 square meters, accounting for sixty-five percent of the total area, formulated the chlorine gas leakage risk accident emergency plan, set up a sudden pollution accident emergency response measures, the
