Poor water quality, need follow-up treatment, there are doctrinal and smell, impact on the environment, low concentrations of sewage treatment is not satisfactory, the temperature impact, process control of complex

Out of the water, and poor water quality requirements for dealing with follow-up, and there is a relatively thick odour, impact on the environment, low concentration sewage treatment result is not satisfactory, and the temperature control of complex processes affecting the large.

Water leakage water quality unsatisfactory, needs following processing, has the thick unusual smell, affects the environment, the low concentration sewage treatment effect is not ideal, the temperature affects in a big way, the craft control is complex

Poor water quality, required subsequent treatment, has a stronger smell, impact on the environment, low concentration wastewater treatment effect is unsatisfactory, temperature, process control complex
