Bojiang Haizi Mine Mine Water Fluorine Removal System Renovation Project

Project scale: 10000m ³/d

Fluoride concentration in raw water: F=6-10mg/L

Water discharge standard: According to the Environmental Quality Standards for Surface Water (GB 3838-2002), the limit requirements for fluoride ions in Class III water are as follows: fluoride ≤ 1mg/L

Project Introduction: The raw water mainly consists of mine goaf water, mine sewage, and fissure water. Dismantle the existing two hydroxyapatite filters in the fluoride removal workshop and replace them with two sets of dedicated air flotation equipment for fluoride and turbidity removal, forming a 2 * 5000m ³/d old air water fluoride removal system.

The project construction has the following characteristics:

1. The project construction cycle is short: demolishing existing equipment, installing new equipment, and debugging, totaling one week.

2. Small footprint: The original hydroxyapatite filter and sedimentation tank were demolished and replaced with a dedicated fluorine removal air flotation tank, reducing the footprint by one-third.

3. Stable water output: The equipment's water output is stable and meets the standard, and the water output is less affected by fluctuations in the incoming water quality, which has changed the previous problem of filter water exceeding the standard.

4. Low operation and maintenance costs: The operation and maintenance costs are low and controllable.
