Integrated wastewater treatment equipment to treat wastewater as follows:
1, biological contact oxidation method. With biological contact oxidation process in the biological reaction tank filled with filler, has been oxygenated sewage submerged all the filler, and a certain flow rate through the filler. In the filler covered with biofilm, sewage and biofilm extensive contact, in the biofilm metabolism, sewage in the agricultural production system pollutants to be removed, so that sewage can be purified.
2, physical treatment method. Separation of sewage through the role of sewage, recycling of wastewater in the insoluble suspended state of pollutants (including oil film and oil beads) of wastewater treatment method.
3, chemical treatment. Through the chemical reaction of integrated wastewater treatment equipment to separate the mass transfer effect, remove the wastewater present dissolved, colloidal state of pollutants or convert them into harmless substances in the wastewater treatment method.
4, biological treatment method. Through the metabolic action of microorganisms, so that the wastewater in solution, colloidal and fine suspended state of the agricultural production system pollutants, into a stable, harmless substances in the wastewater treatment method. According to the role of different microorganisms, biological treatment method can be divided into aerobic biological treatment and anaerobic biological treatment of two types.
