摘要

  • 摘要: 在人工配制的污水中投入一定量的基质,不同条件下振荡培养,评价沸石、炉渣和陶瓷滤料3种基质在不同因素影响下对氨氮(NH4+-N)和总磷(TP)的吸附能力。结果表明,不同吸附时间时,沸石对NH4+-N的吸附效果最好,陶瓷滤料对TP的吸附效果最好;进水浓度对沸石吸附NH4+-N的影响较大,其吸附量随进水浓度的增大而增大,进水浓度对炉渣和陶瓷滤料吸附NH4+-N及炉渣吸附TP影响不大;3种基质对NH4+-N和TP的吸附量均是随吸附剂量的增加而降低,要达到较好的去污效果,应根据实验结果考虑基质投入量;pH值对沸石吸附NH4+-N影响显著,pH值6~7范围内吸附效果最好,pH值8~12的碱性条件有利于基质对TP的吸附。
    Abstract: The three substrates of zeolite, blast furnace slag and ceramic filter were put into constructed sewage to evaluate their absorption capacity to the ammonium nitrogen (NH4+-N) and total P (TP) under different influencing factors. The results showed that at different adsorption times, the zeolite had a best absorption capacity to NH4+-N, and the ceramic filter had a strong absorption effect to TP.The concentration of sewage had a bigger effect on the absorption of zeolite to NH4+-N, and the absorption amount increased with the concentration of sewage increasing, while it had little effect on the absorption of blast furnace slag to NH4+-N and TP, and ceramic filter to NH4+-N.The three substrates absorption amount to NH4+-N and TP decreased with the adsorbent amount increasing. To achieve a better absorption capacity, tests results could be considered based on the substrate inputs. The pH value had a significant effect on the zeolite absorption to NH4+-N, and it had a best absorption effect when pH was at 6~7,whereas when pH was at 8~12 (alkaline conditions),the matrix had a strong absorption to TP.
