The effect and mechanism analysis of pollution control technology based on sewage inspection wells
In order to deepen the understanding of the effects and mechanisms of pollution control technologies based on sewage inspection wells,the red brick,sponge,and electrolytic treatment systems based on sewage inspection wells were constructed,and the control ability and mechanism of pollutants and harmful gases of the three systems were analyzed.The results showed that the red brick,sponge and electrolytic treatment systems can effectively control the water phase pollutants and gas phase odor(OU),H2S and CH4.The red brick treatment system had a strong ability to remove suspended solids(SS),but its removal rate for harmful gases was slow.The electrolytic treatment system had a strong ability to remove chemical oxygen demand,ammonia nitrogen,total phosphorus and sulfide,and the removal rate for harmful gases was faster.The removal ability of sponge treatment system to pollutants and harmful gases was relatively moderate.The control mechanism of the three treatment systems was different.In addition to the removal of pollutants and the control of harmful gases caused by microbial metabolism,the electrolytic treatment system realized the rapid control of pollutants and harmful gases through the electric flocculation effect,and the red brick treatment system improved the removal rate of SS through the physical interception effect.The research results can provide references for the technical application and reaction mechanism of pre-pollution control concepts.
