Description

One kind acidifying, which is blown, heats collection device
Technical field
Gas detection collection technique field is the utility model is related to, heating of blowing is acidified more particularly, to one kind and is collected Device.
Background technology
Underground water (particularly thermal water) and sanitary sewage, usually contain sulfide, a portion is in anaerobic condition Under sulfate reduction or caused by the decomposition of sulfurous organic compound made by the effect of bacterium.Some industrial and mining enterprises, such as coking, make The industrial wastewaters such as gas, ore dressing, weaving, printing and dyeing, papermaking, process hides also contain sulfide.
The multinomial water standard in China and pollutant emission standard are all controlled to Sulfide in water content.Such as《Surface water Environmental quality standards》(GB3838-2002)、《Agricultural irrigation water quality standard》(GB5084-2005)、《Water quality standard for fishery》 (GB11607-89)、《Integrated wastewater discharge standard》(GB8978-1996)、《Iron ore picks up emission of industrial pollutants standard》 (GB28661-2012)、《Petro chemical industry pollutant emission standard》(GB31471-2015) etc..
At present, China indicates iodimetric titration, directly sub-methyl blue spectrum analysis, colour developing for the state of sulfide determination AAS, gas-phase molecular absorption spectrometry method, because iodimetric titration and sub-methyl blue spectrum analysis are easy to operate, instrument is set It is widely used for less demanding.Wherein, iodimetric titration is mainly used in water of the sulfide content more than 0.4mg/L and waste water is surveyed It is fixed;Sub-methyl blue spectrum analysis is mainly used in the analysis of surface water of the sulfide content more than 0.02mg/L.Non- national standard side Method also has Indirect Flame Atomic Absorption Spectrometry, flow injection, online distillation-flow injection, sulfide-selective electrode constant-current titration Method, the electrode of wherein sulfide-selective electrode potentiometric titration is easily damaged and aging, it is difficult to commonly used.
Due to generally containing the suspension for having an impact optical spectroscopy measure and the colourity for influenceing iodometric determination in water and waste water, going back Immunogenic substance etc., therefore few samples can be determined directly.Except online distillation-flow injection and sulfide-selective electrode current potential Outside titration, remaining method is both needed to carry out pre-treatment to sample to eliminate interference.Such as Liu Guanghong et al. in 2009 in experiment section Learn with disclosing " in trade effluent sulfide determine a kind of new partition method " in technical journal, the inside disclose using sulfuric acid with [H] of zinc reaction generation and S2- generation H2S, being heated to 96 DEG C makes its effusion, is absorbed with absorbing liquid, this method reduces air blowing Device.But this is not standard method, its replicability and feasibility are still worth discussion.Four kinds of national standard methods are for turbidity, colourity Larger complex sample, which is required to be acidified-air blowing-, absorbs pre-treatment, to eliminate its interference to measure.
