Description
本发明涉及炼化废水处理技术领域，具体为炼化企业废水生化处理用活性污泥调节剂。
据统计，我国2017年工业废水排放总量约为690亿吨，其中高盐废水占比5％，且每年以2％的速度增长，我国水污染防治所面临的严峻形势。
炼化废水主要由来自电脱盐、催化裂化、常减压、脱硫、冷却***、锅炉等装置。废水成分复杂，污染物的种类多，浓度高、变化大。污染物主要有油类、硫化物、挥发酚、NH4
+-N以及其他有毒物质，对生化***有强烈的危害及冲击性，导致生化效率下降，排水水质下降。
在生化***受到冲击，污泥沉降性能变差，生化效率下降的情况下，有针对性的选用生物增效技术，提高生化***抗冲击性及稳定性，提高污水处理工序的效率，为进一步提高出水质量提供保障。
发明内容
本发明的目的在于：提供一种适用于炼化废水生化处理过程的控制活性污泥沉降比例，抑制丝状菌膨胀，提高活性污泥生物活性及***抗冲击性能的环境友好型药剂。
本发明通过以下技术方案予以实现。

所述的碳源为葡萄糖、果糖、蔗糖、乙酸或丙酸。
所述的氮源为尿素、氯化铵或硫酸铵。
所述的活性炭为粉末活性。
本发明的有益效果：本发明在补充碳源和氮源磷酸盐等微生物必须的营养的基础上通过添加解毒剂、活性炭、膨润土及微量元素及对环境友好的聚谷氨酸等，该调节剂还引入解毒剂，降低了有毒物质的抑制性，通过引入膨润土及活性炭增加了活性污泥的密度及为菌胶团菌提供了附着物为菌胶团菌与丝状菌的竞争中提供了环境优势，控制了丝状菌膨胀。同时抑制非丝状菌膨胀。缩短炼化污水生化处理过程中活性污泥培养与驯化的时间，提高驯化污泥中有益菌的总量及处理***的稳定性。
本发明的生化处理用活性污泥调节剂以炼化废水的实际指标为基础，针对污水生化处理机理及活性污泥膨胀机理，有针对性的配置，若其他药剂要实现此功能，需要分别添加多种药剂，成本高、药剂投加不容易控制和计算。本药剂使用简单，投加量根据精确可控，相对使用成本低。
