For a first-tier city like Shanghai, environmental approval is relatively strict. On the one hand, the city image problem, but also because the Yangtze River Delta, Beijing-Tianjin-Hebei, Pearl River Delta region is China's key air pollutants control area, in which the oil smoke pollution is a key control object.
Soup dumpling store with fried food will have fumes, simple soup dumpling store will also have odor emissions, in addition to the operation process will produce oily sewage, exhaust fan noise, and so on.
To choose the site is reasonable (and sensitive buildings have appropriate health protection distance), there is waste water grease trap, there is smoke emissions to be on the smoke purification equipment, fixed kitchen garbage storage device (cover processing, timely removal) and other conditions to obtain environmental approval procedures.
