Industrial waste water is abnormal, you can do so
Within the scope of its own design capacity, the sewage treatment plant treats the incoming sewage so that the effluent quality can be discharged up to the standard. However, abnormal water intake is inevitable.
So how to do the emergency treatment of abnormal water intake in sewage treatment plants?
Abnormal water intake - Basic situation
1) Illegal discharge of industrial wastewater;
2) Excessive inflow of deposited pollutants in the pipeline caused by a long-term shortage of water intake and sudden resumption of a large amount of supply;
3) Water intake anomalies caused by continuous heavy rainfall;
4) Due to the drainage of subsequent structures of the sewage treatment plant itself, a large amount of sediment is returned to the water intake, resulting in abnormal water intake of the sewage treatment plant.
Second, abnormal water intake - emergency treatment measures
1) Install water inlet warning
Install online pH probe, online COD monitor and other online monitoring instruments in the water inlet, such as abnormal situation can be warned in time.
In addition, personnel in the inspection is also essential, such as:
Abnormal pH and cod data, obvious pungent, disgusting smell in the water, or obvious blue or yellow color in the water, should be reported to the factory director and production technical supervisor in time;
When the sewage drains the subsequent structures, a large amount of sediment in the reflux is too much, which exceeds the load that the system can bear, and the biochemical system is seriously impacted, it is necessary to ask the superior in time.
2) Adjustment of sewage treatment facilities
When it is found that the amount of incoming water is large and exceeds the process design standard, it is necessary to carry out technical transformation of the existing sewage treatment facilities to ensure that the sewage can be discharged up to the standard.
3) Emergency treatment of sudden and short time exceeding the standard
Such as ammonia nitrogen, phosphorus, heavy metals in the wastewater exceed the standard, chemical agents can be added to the wastewater to quickly deal with the sudden exceeded problem.
