Up to now, the River Black-odor issues, Haishu urban management Department found no human causes, and if the public found the river of sewage, can call Haishu Chengguan hotline 87103110 report it.

"Initially, we infer, river water blackened stinks mainly is caused by the silt on the bottom of the river. "BI for everyone.

"Why rivers of mud are hurrying to turn both the sky? "Pressed by reporters said.

Is the second Inland communication outside the River in the exports have been blocked because of the Bao Feng Zha is expanding. It can be said that rivers to a near halt, mud is not the river flows, accumulate serious.

Third, Ningbo, two days into the rainy season, hot weather and low air pressure, adding on the river bottom mud, easily lead to fish kills.

Water blackening and stink to do? BI for everyone, Feng sluice extension project is completed, sometime in mid-July, yaojiang River within water and be able to communicate with mud water flows, it will be much better. The second half of the Haishu Chengguan Department imposed on Huang Jiahe river dredging, further enhance water activity.

There contingency measures?

"There are. We plan to enable mobile Nano bubble generator and a variety of biological agents temporarily alleviate the problem of water blackening and stink. Artificial oxygen into the River, river flows, to ease black and odorous. "BI for everyone, mobile Nano bubble generators need to be loaded on a ship in order to use, work process may produce noise, also public understanding.
