Research on water quality monitoring and comprehensive treatment measures for black and odorous river channels
In order to improve the treatment efficiency of black and odorous river water,a sewage sample from a certain black and odorous river was taken as the research object.The water quality at different sampling points and different sampling time periods was monitored and analyzed.A combination of"microporous aeration+biomass adsorption material+microbial agent"technology was used to comprehensively treat black and odorous river sewage,and the influence of different factors on the sewage treatment effect was investigated.The results show that the average transparency,dissolved oxygen(DO),redox potential(ORP),and ammonia nitrogen(NH3-N)concentration of water samples taken at different time points in the target black and odorous river reach the standard for mild black and odorous water,indicating serious pollution of the river water quality.Under the conditions of aeration intensity of 250L·h-1,biomass adsorption material dosage of 8g·L-1,and microbial agent dosage of 0.035g·L-1,the combined process of"microporous aeration+biomass adsorption material+microbial agent"significantly improved the water quality indicators of river sewage,eliminated the black and odorous phenomenon of the river,and achieved good comprehensive treatment effect.
