摘要： A process to treat a gas comprising hydrogen sulphide and mercaptans is described. The following steps are part of this process: (a) contacting the hydrogen sulphide and mercaptans comprising gas (1) with an aqueous solution (3) comprising sulphide-oxidising bacteria thereby obtaining a loaded aqueous solution (5) and a gas (4) having a lower content of hydrogen sulphide and mercaptans, (b) contacting the loaded aqueous solution with mercaptan reducing microorganisms immobilized on a carrier under anaerobic conditions, (c) separating the aqueous solution obtained in step (b) from the mercaptan reducing microorganisms to obtain a first liquid effluent (7), and (d) contacting the first liquid effluent (7) with an oxidant (9) to regenerate the sulphide-oxidising bacteria to obtain a second liquid effluent (11) comprising regenerated sulphide-oxidising bacteria. The sulphide-oxidising bacteria as present in step (a) are comprised of regenerated sulphide-oxidising bacteria obtained in step (d).

摘要： An economical method for recovering phosphate or phosphate and nitrogen from liquid streams. A liquid containing phosphate is introduced into a culture of autotrophic microorganisms in the presence of natural or artificial light, thereby producing a liquid effluent with elevated pH and reduced alkalinity. The alkalinity is reduced through the consumption of bicarbonate/carbonate by the autotrophic microorganisms. The effluent is then chemically treated with low-cost chemicals to provide Ca++ or Mg++ ions necessary to form a phosphate precipitate such as calcium phosphate or magnesium-ammonium-phosphate (MAP). The autotrophic microorganisms can be cultivated in ponds, lagoons, or photobioreactors. The pH of the culture is adjustable within a preferred range of 7.5 to 10.5 by adjusting the photobioreactor operation. The process includes an economical flotation separator for solid, liquid, gas separation and a means of concentrating ammonia nitrogen that may also be removed during the process of phosphate reclamation.

摘要： A method of removing organic carbon in biological wastewater treatment includes the steps of: (a) oxidizing organic carbon to carbon dioxide with elemental sulfur as an electron carrier, and reducing the elemental sulfur to sulfide; (b) oxidizing the sulfide to elemental sulfur by recycled nitrate through controlling one or more of a recycling ratio to maintain an oxidation reduction potential (ORP) within the range of −360 my to −420 mv, using an auto ORP controller; (c) recycling the elemental sulfur formed during oxidation of the sulfide back to the oxidation of the organic carbon; and (d) oxidizing ammonium to nitrate then partially recycled back for sulfide oxidation.
