Chemicals are commonly dosed in sewer systems to reduce the emission of hydrogen sulfide (H2S) and methane (CH4), incurring high costs environmental concerns. Nitrite dosing is a promising approach as nitrite can be produced from urine wastewater, which feasible integrated water management strategy. However, usually requires strict conditions, e.g., relatively concentration (e.g., ∼200 mg N/L) acidic environment, inhibit microorganisms. In contrast "microbial inhibition", this study proposes utilization" concept, i.e., utilizing substrate for H2S CH4 consumption sewer. laboratory-scale reactor, at low concentrations 25–48 N/L was continuously dosed. Two nitrite-dependent microbial utilization processes, anaerobic oxidation (n-DAMO) oxidation, successfully occurred conjunction with reduction. The occurrence both processes achieved 58 % reduction dissolved over 90 removal activities measured 15.6 CH4/(L·h) 29.4 S/(L·h), respectively. High copy numbers n-DAMO bacteria sulfide-oxidizing (SOB) were detected biofilms sediments. Mechanism analysis confirmed that level did not cause inhibition sulfidogenic process due downward migration activity zones Therefore, proposed concept offers new alternative simultaneous sewers.
