Chemical dosing is the most used strategy for sulfide and methane abatement in urban sewer systems. Although conventional physicochemical methods, such as oxidation (e.g., oxygen/nitrate), precipitation iron salts), pH elevation magnesium hydroxide/sodium hydroxide) have been since last century, high chemical cost, large environmental footprint, side-effects on downstream treatment processes demand a sustainable cost-effective alternative to these approaches. In this paper, we aimed review currently chemicals significant progress made technology, including 1) use of bio-inhibitors, 2) situ production, 3) an effective strategy. To enhance cost-effectiveness applications systems, two research directions emerged: online control optimization strategies integrated wastewater The integration approaches offers considerable system-wide benefits; however, further development comprehensive studies are required.

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.
