- Abstract:
- In order to provide government and enterprises with effective suggestions for the management of sewage treatment plants, we analyzed the public information big data from the Micro-blog third-party supervision platform and the Xi’an Ecological Environmental Protection Bureau, and studied the current status of domestic sewage treatment plants. The results show that the number of complaints from sewage treatment plants is positively correlated with GDP and the number of industrial enterprises over designated size. Higher chemical oxygen demand and ammonia nitrogen concentration usually are the two main causes exceeding the wastewater treatment limits. Seventy-nine percent cases exceeding the limits are short-term. Twenty-one percent cases are long-term. The severe exceeding limits phenomenon occurs in winter. The company’s feedback on exceeding limits is mainly based on the equipment failure. The government needs to unblock public participation channels and ensure the scientificity of emission standards as well as the assessment indicators. Sewage treatment plants should ensure the authenticity of the feedback content, repair equipment in time, and pay attention on the problem of exceeding limits in winter.
