ANAEROBIC SUSPENDED GROWTH WATER TREATMENT OF CONTAMINATED WATER

摘要

A system may include a reactor, in which an anaerobic environment exists, that includes a slurry of at least contaminated water and a mixed bacterial culture of facultative bacteria and anaerobic bacteria. The mixed bacterial culture may be suspended within the slurry. The contaminated water may include contaminants associated with a non-metal, a metal, or a metalloid. The mixed bacterial culture may react with the contaminated water to reduce or remove the contaminants from the contaminated water to create a treated slurry. The reactor may output the treated slurry. The system may also include a filtration device to receive the treated slurry; remove, from the treated slurry, the mixed bacterial culture and the contaminants, reduced or removed from the contaminated water, to create treated water; and output the treated water.

1. A treatment system to treat contaminated water, the treatment system comprising:
a reactor, in which an anaerobic environment exists, that includes a slurry of contaminated water, organic material, and a mixed bacterial culture that includes facultative bacteria and anaerobic bacteria,
the mixed bacterial culture being suspended within the slurry and not attached to a physical substrate associated with attached growth technology,the contaminated water including contaminants associated with at least one of a non-metal, a metal, or a metalloid, andthe organic material acting as an electron donor for the mixed bacterial culture that enables the mixed bacterial culture to react with the contaminated water to reduce or remove the contaminants from the contaminated water, the reactor is to:
output, as a treated slurry, the organic material, the mixed bacterial culture, and the contaminated water from which the contaminants have been reduced or removed; and a filtration device to:
receive the treated slurry,remove, from the treated slurry, the organic material and the mixed bacterial culture, andoutput, as treated water, the contaminated water from which the contaminants have been reduced or removed.
