一种养猪废水的处理方法
摘要：
本发明属于废水处理技术领域，具体涉及一种养猪废水的处理方法。本发明的养猪废水的处理方法包括以下步骤：将农作物秸秆、厌氧污泥和养猪废水混合，然后厌氧发酵5～10天，即得。优选的，本发明的养猪废水的处理方法具体包括以下步骤：1)将农作物秸秆和厌氧污泥加入到缺氧池或缺氧容器中；2)向缺氧池或缺氧容器中持续注入养猪废水，使养猪废水在缺氧池或缺氧容器中停留5～10天后排出。本发明使用廉价易得的农业废弃物秸秆预处理养猪场的沼气池出水，有效降低了沼气池出水的总氮浓度，补充了碳源、调整了碳氮比，保证后续生态湿地处理效果。
摘要（英）：

The invention belongs to the technical field of wastewater treatment, and concretely relates to a method for treating pig raising wastewater. The method for treating pig raising wastewater comprises the following processes: mixing of crop straws, anaerobic sludge and the pig raising wastewater, and anaerobic fermentation for 5-10 d, and preferably comprises the following steps: 1) adding the cropstraws and anaerobic sludge to an anoxic tank or an anoxic container; and 2) continuously injecting the pig raising wastewater into the anoxic tank or the anoxic container, allowing the pig raising wastewater to stay in the anoxic tank or the anoxic container for 5-10 d, and then discharging the pig raising wastewater. The cheap and easily available agricultural waste straws are used to pretreat the methane tank effluent of a pig farm in order to effectively reduce the total nitrogen concentration of the methane tank effluent, and supplementation of a carbon source and adjustment of a carbon/nitrogen ratio are carried out to ensure the subsequent ecological wetland treatment effect.
