Use of chlorine-resisting strain S616

Abstract

Use of chlorine-resisting strain S616 lies in treatment of high-concentrated chlorine-ion-contained waste water. The process is carried out by selecting Bacillus firmus S616, culturing in enlargement culture medium for 20-24hrs in proportion of Bacillus firmus S616: high-concentrated chlorine-contained waste water= (1-4):50, inoculating Bacillus firmus S616 in high-concentrated chlorine-ion-contained waste water, constant-temperature culturing at 30-40 degree and pH=7.0-8.0 and reacting for 48-72hrs. It can degrade high-concentrated organic pollutant efficiently and remove COD in waste water in 72hrs.

Description

technical field [0001] The invention relates to the application of a chlorine-resistant microorganism. Background technique [0002] High-salinity refractory organic wastewater, such as petroleum exploration, chemical, pharmaceutical and other wastewater, has become a worldwide technical problem in the field of environmental protection water treatment. However, the hydrochloric acid method turmeric saponin production wastewater is representative of the high-concentration saline refractory organic wastewater. On the one hand, this type of wastewater has complex components, many refractory organic substances, and poor biodegradability of the wastewater; on the other hand, the wastewater has a high salt content and a high concentration of chloride ions, and the concentration of chloride ions in the mixed wastewater can reach 20,000 mg / L. At present, non-biological methods and biological methods are used for saline organic wastewater. The non-biological method is unacceptable t...
