| titleOfInvention | A kind of method that gas field sulfur-containing waste water ULTRASONIC COMPLEX controlled oxidation reclaims elemental sulfur |
| abstract | The invention discloses a kind of method that gas field sulfur-containing waste water ULTRASONIC COMPLEX controlled oxidation reclaims elemental sulfur, belong to sewage treatment area, comprise the following steps successively：Gas field sulfur-containing waste water is pre-processed；Pretreated gas field sulfur-containing waste water and acid-base modifier are pumped into mixing tube logos and utensils, the initial [H of control waste water + ] concentration, mixed liquor in mixing tube logos and utensils is delivered under ultrasonic field in stirred reactor, it is pumped into simultaneously in hydrogen peroxide and nano-powder, course of reaction by acid-base modifier, oxidant dosage and waste water sulphur analysis control system oxidation-reduction potential (ORP)；Stirring intensity, supersonic frequency and the sound intensity are controlled during stirring reaction；Waste water filtering, the simple substance sulfur recovery of generation after reacting.The present invention can controllably obtain high elemental sulfur yield as much as possible while high desulfurization degree is kept as far as possible, and method is simple to operate, rapidly and efficiently. |
