稳定塘污水处理技术的研究进展

Study on the development of sewage treatment technology by stabilization pond

总结了稳定塘中有机物、氮、磷的去除机理,稳定塘中的有机物主要通过微生物降解、有机物吸附、有机颗粒的沉降和截滤作用去除;硝化/反硝化、水生植物吸收、NH3挥发这3个过程为TN的主要去除机制;磷的去除涉及底泥对PO43-的吸附/解吸、有机磷氨化、磷的扩散、水生植物吸收等多种机制的共同作用。介绍了新型稳定塘技术以及塘与传统生物法组合、各类塘型组合工艺。指出今后的稳定塘将朝着强化机理、提高效率、完善设施、塘型优化组合方向发展。

This paper have summarized the mechanism to wipe off the organization, nitrogen, phosphorus. In the stabilization pond, the organinzation was mostly wiped off by animalcule degradation, organinzation adsorption, sedimentation and intercepted action, the mainly wiped mechanism of TN included nitration/innitration,hydrophyte absorbed, NH3 volatilization, wiped off phosphorus related to many mechanisms action,which include adsorption/suck of PO4^3- by buttom mud, the aminate of organic phosphoric pervasion, hydrophyte absorbed and so on. This paper has introduced the new pattern of stabilization pond technology, as well as the combination of pond with traditional biological method, all kinds of pong pattern combination technics, pointed out the stabilization pond will be developed to direction of consolidated mechanism,enhanced efficiency ,consummated establishment ,optimized combination of pond patterns in future.
