Lead is a metal element widely used in the chemical industry, especially in battery manufacturing and alloy production. However, the waste water discharge of lead will cause serious pollution to the environment, so it is necessary to develop efficient lead removal technology. The combined extraction centrifugal extractor provides an innovative solution for lead extraction.

Chemical properties and environmental effects of lead

Lead is usually found in water bodies in the form of lead ions (Pb² +). The excessive presence of lead can cause significant toxicity to aquatic life and may cause human health problems. Therefore, proper treatment of lead-containing wastewater is an important task to protect the water environment.

Separation mechanism of combined extraction centrifugal extractor

The combined extraction centrifugal extractor relies on centrifugal force generated by high-speed rotation to separate lead ions from wastewater. The specific steps include:

1. Waste water feeding: Lead waste water into the equipment.

2. Centrifugal separation: The equipment rotates at high speed, and the lead ion settles due to its density.

3. Precipitation collection: Collect settling lead precipitation through the discharge system for subsequent treatment.

Optimized extraction conditions

Key conditions for improving lead extraction efficiency include:

1. Centrifugal speed: It is recommended to be between 4000-6000 rpm to improve the settling speed of lead.

2. Processing time: Appropriate extension of processing time can usually improve the extraction rate of lead, and the recommended time is 15-25 minutes.

3. pH adjustment: Under acidic conditions (pH 4-6), the separation effect of lead is better.

Follow-up treatment and resource recovery of lead

The extracted lead precipitates can be recovered by roasting and chemical treatment, so as to realize the reuse of lead and reduce the environmental risk.

The study on extraction of lead element by combined extraction centrifugal extractor in chemical industry provides an efficient technical means for the field of environmental protection and has a broad market application prospect.
