Water Treatment Integrated Machine, based on the operation experience of domestic wastewater treatment plants, combined with our scientific research achievements and engineering practices, we have designed an integrated organic wastewater treatment unit. The primary focus of the Water Treatment Integrated Machine is on the treatment of domestic wastewater, utilizing a mature biochemical treatment technology, the Contact Oxidation method. The sludge settled in the sedimentation tank of the water treatment integrated machine is transferred to the acidification sedimentation tank for further digestion, thus minimizing the remaining sludge in the system. The working procedures of the main control equipment, such as the fan and submersible pump, are automatically adjusted to reduce manual labor and ensure automatic operation, thereby minimizing unnecessary human damage. By employing the contact oxidation process primarily for the removal of organic pollutants, the removal rate of pollutants is improved, ensuring the effluent meets the standard for discharge. Additionally, with the extended contact oxidation time, the NH3-N is also converted while organic pollutants are removed. The wastewater treatment system is equipped with a real-time water quality monitoring system, including flow rate, pH value, and residual chlorine, for timely monitoring of effluent quality and adjusting equipment operation status. The treatment system is modularized, making construction simple and convenient.
