The development and optimal allocation of water resources in Zhidan country energy chemical industrial park

Focusing on the water shortage and water stress during the construction period of Zhidan energy chemical industrial park, the optimal allocation of water resources in Zhidan was conducted, in order to guarantee the water demand of the energy chemical industrial park. The optimal allocation of water resources is based on the advanced investigating and analyzing on the potential of four kinds of available water in this industrial park (surface water, underground water, the rain-flood and the recycled water). As well as the principle of optimal allocation is to reduce the conventional water exploitation and to increase the unconventional water resource utilization. The study result shows, the recent total water resources in this park is 12.39×10⁴ m³/d and the forward total water resources is 13.39×10⁴ m³/d, which can meet the requirement of both recent and forward water consumption for this park(4.40×10⁴ m³/d and 5.16×10⁴ m³/d). The optimal allocation of water resources program is to achieve the goal of reaching a recent water supply of 4.5×10⁴ m³/d, among which the underground water is 0.95×10⁴ m³/d, the surface water is 3.0×10⁴ m³/d, the recycled water is 0.5×10⁴ m³/d, the rain-flood water is 0.05×10⁴ m³/d. While for the forward water supply of these 4 available kinds of water are 1.45×10⁴ m³/d, 3.0×10⁴ m³/d, 1.0×10⁴ m³/d, 0.05×10⁴ m³/d respectively with a total supply of 5.5 ×10⁴ m³/d.
