How to solve the problem of substandard effluent from Water Treatment Equipments

1. The operator of the integrated water treatment equipment has a weak sense of responsibility, improper operation methods, and does not pay attention to details. Common problems include: there is a problem with the incoming water, and the machine is not stopped for treatment in real time. The instruments and probes of the equipment are not calibrated and cleaned frequently. The concentration of the prepared drugs does not meet the standards, and the concentration is reduced without authorization.

2. In order to make the water treatment meet the standards, it is necessary to operate the equipment correctly, strictly standardize the classified wastewater, control the pH value of the sewage, and control the amount of lime to reduce the output of sludge.

3. The chemicals used for classified wastewater are highly targeted. In order to reduce the cost investment, the chemicals used will be reduced. Therefore, even if the wastewater of each classification is well treated, the overall comprehensive treatment is not up to standard.

4. The pH value of the water increases, and the pH adjustment control in the pool is unstable:

① The unstable pH forms the sedimentation pool, which causes the effluent quality of the integrated water treatment equipment to be substandard.

② In order to make the sewage water clear and reduce the cost, some people will use a large amount of lime, but this will produce a large amount of sludge. 30%-40% of the cost of wastewater treatment is caused by the treatment of sludge.

5. The integrated water treatment equipment needs to be pre-treated before surface treatment:

① The degreasing powder used in the pre-treatment contains emulsifiers, and a large amount of emulsifiers not only affects the content, but also affects the alum floccules in the sedimentation tank, the mud is not ideal, and the sedimentation is not good.

② A large amount of suspended matter follows the lower clean water out of the sedimentation tank, and dissolves into the water again when the pH is adjusted, resulting in the phenomenon of excessive heavy metal ions at the disch
