Description
技术领域
本发明涉及净水剂技术领域，具体涉及一种污水处理微生物营养液的制备方法。
背景技术
目前，污水处理过程中脱氮和菌种培养需要使用大量的碳源和磷源，包括工业级葡萄糖、乙酸钠、甲醇、磷酸二氢钾等微生物生存需要物质。目前脱氮碳源多采用葡萄糖、乙酸钠和甲醇，在应用过程中存在一定的问题，在水处理中葡萄糖长期使用易引起污泥沉降性能差，二沉池出水携带污泥，影响出水；乙酸钠作为碳源使用因含有7个结晶水，可使用的碳源成份低，性价比低，运行成本高；虽然甲醇是比较好的碳源，但因消防、安全措施要求严格，限制了甲醇在水处理工业的应用；随着国家环保部门对总氮指标要求越来越严，微生物营养液的是污水处理厂的迫切需要，将会有广泛的市场；综上所述生产一种价格低廉、安全、性价比高的微生物营养液势在必行。
发明内容
本发明目的是提供一种污水处理微生物营养液的制备方法，制得的营养液在水处理中对总氮去除效果好，且成本低、稳定性好，微生物活性、吸附性能增强。
污水处理微生物营养液的制备方法，具体包含以下步骤：
1.室温条件下，按液体原料废玉米浆：甲醇＝7:3的比例将原料混合均匀；
2.将步骤1混合的溶液用泵打入密闭反应容器内，同时每立方混合溶液加入磷酸溶液10kg，反应时间为3-4小时、反应温度为30-90℃，从而完成原料间发生的氧化、聚合反应；
3.稳定熟化3小时后，经过板框过滤后，制成液体微生物营养液,存放暂储罐。
由于采用了以上技术方案，本发明具有以下有益效果：由本发明制得的营养液在水处理的过程中，投加到生物池内，碳、氮、磷比例适中，非常符合微生物生长的需要，脱氮效果好，微生物活性强，而且对于含氮量高的工业废水、难处理工业废水具有很好的处理效果，即本发明制备的微生物营养液与传统碳源相比，不仅去除废水中的总氮，对COD的去除效果也有一定的提升，具有广泛的开发价值和应用前景。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合实施例，对本发明进行进一步详细说明，应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例
污水处理微生物营养液的制备方法，具体包含以下步骤：
1.室温条件下，按液体原料废玉米浆：甲醇＝7:3的比例将原料混合均匀；
2.将步骤1混合的溶液用泵打入密闭反应容器内，同时每立方混合溶液加入磷酸溶液10kg，反应时间为3-4小时、反应温度为30-90℃，从而完成原料间发生的氧化、聚合反应；
3.稳定熟化3小时后，经过板框过滤后，制成液体微生物营养液,存放暂储罐。
利用上述制备方法制得的营养液的产物指标为：微生物营养液1ml溶解在1L水中指标为：碳源690.1mg/L，氮源30.1mg/L，总磷1.5mg/L，不溶物低于0.1％，密度1.05克/厘米3。
实施例2
取一工业企业的生产废水水样，原水样COD150mg/l、总氮40.8mg/l，总磷0.6mg/l，添加2.5ml/l，搅拌沉淀后，水样的COD降低到73mg/l、总氮10.4mg/l，总磷0.28mg/l，污泥沉降性能好，活性强，除磷、脱氮等处理指标达标，成本低，特别对工业废水总氮的去除效果尤为显著。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
