Zhuzhou City’s Sewage Plant Paralysis Sparks Alarming Trend in Sewage Treatment Challenges

The sewage treatment plant in Zhuzhou City faced a critical issue—system paralysis. The impact of excessive water inflow has been a recurring nightmare for downstream sewage plants, leading to shutdowns and potential fines for regulatory violations. Recent reports from Hunan Environment Department shed light on one such incident in Zhuzhou City.

The environment department received alarming news on October 27 about a local domestic sewage plant’s treatment system experiencing sudden paralysis. Upon investigation, officials found the sewage in the facility to be disconcertingly black and odorous, rendering the treatment equipment ineffective. The main outlet showed no signs of operation.

This isn’t an isolated case; Hunan environment department has reported dozens of similar incidents within the last two years. Industrial enterprises contribute significantly to the problem, with unauthorized wastewater discharge causing severe issues for sewage plants across different regions.

Examples of these incidents include an enterprise in Huaihua transferring wastewater into a domestic sewage pipe network, disrupting a local sewage plant. Similarly, sewage treatment plants in Puyang, Suzhou, and Shandong Province faced challenges due to abnormal water quality and high concentrations of industrial wastewater.

The consequences for affected sewage plants are severe, ranging from equipment damage to fines imposed by environmental authorities. To minimize the impact of water inflow and respond effectively, sewage treatment plants must implement robust emergency measures.

In responding to abnormal water inflow, sewage treatment plants should promptly report incidents to local environment departments and retain water samples. Emergency plans should align with regulatory requirements, taking into account factors like chemical oxygen demand, ammonia nitrogen concentration, and total phosphorus concentration.

Effective early warning systems involve installing online monitoring equipment in upstream pipelines to detect abnormal emissions from industrial enterprises. This proactive approach allows sewage treatment plants to make process arrangements in advance, preventing excessive water outflow.
