摘　　要：针对西安市污水处理厂出水TP无法稳定达到一级A排放标准的问题，对西安市7座主要污水处理厂的除磷效果和运行情况进行考察调研，认为除第三污水厂外，其他6座污水厂出水TP含量均无法达到GB18918--2002一级A标准，出水TP的质量浓度一般在0．6~0．9mg／L，建议各水厂重视厌氧区碳源分配和NO3-N含量以及回流污泥水等影响除磷效果的制约因素，为污水处理厂的提标改造提供参考与借鉴。The phosphorus removal and operation of Xi＇an seven major wastewater treatment plants were investigated and studied. The results show that the total phosphorus of effluent in other six wastewater treatment plants can not reach the level of GB 18918 --2002 A standard, except the third wastewater treatment plant. The mass concentration of TP of outflow is 0.6~0.9 mg/L, The wastewater treatment plants should concern the restricted factors that affect the phosphorus removal such as distribution of carbon source and nitrate content in the anaerobic zone and return sludge water, so that reference and experience can be provided for the upgrading and reconstruction of wastewater treatment plants.
