A certain industrial park sewage is keeping in operating companies unified handling, but recently, deal with some problems in processing, mainly caused by error.According to operating the company's response to LHJ, there is a part of the sodium sulfide(sulphide) into the sewage system,  when it started I didn't know, directly into the UASB. The second day of UASB effluent COD 1500 increased to 4000 mg/l, oil VFA increased from 400 to 900 mg/l.Then, call the LHJ to the relevant information and deal with the problem, please kindly find details hereunder-Tianjin Damon.                                                                      

Q:

1.Hydrogen sulfide(sulphide) poisoning is suspected, want to help and see if it is for this reason-Tianjin Damon?

2.How much is the tolerance level the anaerobic to Hydrogen       sulfide(sulphide) or negative bivalent sulfur root-Tianjin Damon?

3.What measures should be taken to remedy a sulfur poisoning-Tianjin Damon?

A:                                                                                       1. VFA increased microbial synthesis of methane reduction, activity is poisoning, judging is sulfide(sulphide) from excess YanYangChi not normal-Tianjin Damon.

2. Hydrogen sulfide(sulphide) more than 50 PPM influence is very big, the tolerance limit of sulphide is 40 PPM-Tianjin Damon.

3. To add a small amount of YanYangChi remove excess ferrous sulfide(sulphide), increase YanYangChi ventilated, make the diluted hydrogen sulfide, and the appropriate high pH value, increase the load to remove residual sodium sulfide(sulphide)-Tianjin Damon.
