Hydrogen sulfide (H 2 S) is a toxic gas widespread in injected water of secondary oil recovery, having disadvantages of serious corrosion equipment, health risks, and higher operational costs. This study focused on the field application with nitrate and nitrite injection, which has been less examined in previous studies. A bioinhibitor (400 mg/L nitrate + 300 mg/L nitrite) was reinserted into the water of the M71 oilfield (Jianghan Basin, China) with serious souring. The concentration of H 2 S decreased by 83% from 30 mg/L to less than 5 mg/L; the nitrate-reducing bacteria (NRB) counts increased from 10 to 100 cfu/mL, and the sulfate-reducing bacteria (SRB) counts remained at low numbers (0 cfu/mL). The dominant genera in the injected water in the absence of the bio-inhibitor were Desulfuromonas, Halanaerobium, and Desulfovibrio. NRB-related Halomonas and Marinobacter and sulfide-oxidizing bacteria of Halothiobacillus and Pseudomonas were activated through competing with SRB electron donors, and sulfide-oxidizing bacteria oxidized H 2 S to S 0 or SO 4 2− to suppress SRB when the bio-inhibitor was continuously added. The nitrite inhibited SRB metabolism through suppressing sulfite reductase activity. These findings indicated that the addition of the bio-inhibitor could remove H 2 S efficiency in injected water, thereby causing water reinjection in the oil reservoir. As a result, cost-effective treatments for souring control are achieved.

“…The results showed that BCCP could improve the degradation efficiency of NH 4 + -N as the carrier of immobilized AOB. Due to the porous structure of the biochar sphere that provides a larger surface area and more pores, it can store more substrates and promote the growth of microorganisms [21].…”

Immobilized microbial materials can effectively remove pollutants from surface water, and a biochar/clay composite particle (BCCP) material is prepared with immobilized Flavobacterium mizutaii sp. and Aquamicrobium sp. to remove ammonia nitrogen (NH4+–N) and petroleum hydrocarbons (PHCs). The results indicated that the optimal ratios of biochar, Na2SiO3 and NaHCO3 were 15%, 3%, and 3%, and the adsorption process was found to be better described with the pseudo-second-order kinetic equation. The individual immobilization of Flavobacterium mizutaii sp. and Aquamicrobium sp. with sodium alginate–polyvinyl alcohol (PVA + SA) achieved 80% and 90% removal efficiencies for NH4+–N and PHCs at the 10th d. The composite immobilization of two efficient bacteria could degrade 82.48% NH4+–N and 74.62% PHCs. In addition, immobilization relieved the effects of temperature and salinity. This study can provide guidance for the application of immobilized microbial composite materials in natural water environments.

“…32 It has been found that organic support is strengthened and improved in the adsorption of pollutants by adding inorganic substances such as clay, halloysite nanotubes and activated carbon. 18,[33][34][35] Attapulgite clay (ATP) is an aluminum-magnesium silicate mineral, a rare non-metallic mineral resource. ATP has been widely used in wastewater treatment due to its unique brous crystal structure and superior physical and chemical properties such as colloid, adsorption, catalysis and lling.…”
