example 1
[0101] Example 1: The first bid section of the Special Project for Agricultural Non-point Source Pollution Control in the Yangtze River Economic Belt in Qingshen County is to conduct point-to-household treatment of scattered suburban and rural domestic gray water to remove pollutants so that they can be naturally scattered and discharged, irrigated farmland, and reduce pollution. For the purpose of polluting the environment and soil, the treatment system has 5-10m 3 / d Build brick-concrete structure pool and 0.5~2m 3 / d Finished FRP pool; of which 0.5~2m 3 / d Accounting for most of the construction of this project is the control project of this tender section, with a contract value of about 21 million yuan.
