Tianjin Development Zone Pump Station Relieves Pressure on Sewage Treatment

It was learned from Tianjin Development Zone that the sewage effluent pumping station in the development zone began operation on the evening of December 7. After the completion of the operation, the sewage in the development zone can be effectively channeled to the Beitang Wastewater Treatment Plant, which greatly relieves the pressure on the sewage treatment in the development zone and provides strong support for the improvement of infrastructure service functions in the development zone.

It is reported that the sewage effluent pumping station and the outlet water pipeline project of the development zone is located between Xueyuan North Road and Donghai Road of the Development Zone, covers an area of ​​2052 square meters, and the pump room construction area is 440 square meters. The design scale is 2.486 cubic meters per second. Including a one-piece pump room, two-row water intake pipeline 480 meters, a single-row pressure outlet pipe 1160 meters. The project started construction in August 2010.

Auto Halogen Lamps

Auto Halogen Lamps

A type of Auto Lamp that used quartz as glass shell and filled with halogen gas gives a very bright light. Principle is inside the halogen bulb such as injection of iodine or bromine, under high temperature, the sublimation of chemistry with halogen tungsten filament, tungsten will be cooled to solidification on tungsten filament, form balanced circle, avoid premature tungsten filament fracture. So halogen bulbs live longer than incandescent bulbs. The supply voltage of halogen lamp is usually divided into ac 220V and dc 12V and 24V. The halogen lamp is made of tungsten, but it is enclosed in a smaller quartz glass shell. Because the glass is very close to the filament, if it's made by normal glass, it will melt very easily. The gas in the glass is composed of different gases. These gases have a very interesting feature. They are combined with tungsten vapor. If the temperature is not high enough, the halogen gas combines with the tungsten vaporization and redeposition of the filament. This cycle makes the filament can last more time. Halogen bulb is hotter than a normal bulb.
