AI Technical Summary

Technical Problem

Dust pollution caused by loading, unloading and transporting coal in coal yards is serious, and there is a lack of effective wastewater treatment systems in the existing technology, which makes it difficult to recycle water resources and results in a large water consumption.

Method used

Design a multi-source water supply system for a coal plant, including a sedimentation unit, a collection unit, and a treatment unit. Through sedimentation, collection, and treatment of wastewater from coal plant equipment, rainwater, and spray wastewater, a water resource supply system for recycling is formed.

Benefits of technology

Effective collection and treatment of various water resources in the coal yard reduces water waste, realizes water recycling, and lowers the water consumption of the coal yard.

Abstract

Disclosed in the present invention is a multi-source water supply system for a coal yard, comprising: a sedimentation unit used for collecting and treating wastewater from coal yard equipment; a water utilization end connected to the sedimentation unit; a collection unit used for collecting rainwater and coal yard spraying wastewater; and a treatment unit connected to the collection unit and used for treating the wastewater collected by the collection unit. The treatment unit is connected to the water utilization end, and can treat the collected rainwater and coal yard spraying wastewater and then supply same to the water utilization end for use. By providing a treatment unit, a collection unit, and a sedimentation unit, various water resources in a coal yard can be effectively collected and used after treatment, thereby effectively avoiding the waste of water resources.
