The treatment process at home and abroad are mature, very different. Secondary treatment is the use of chemical and biological methods, mainly by means of microbial life to remove waste water sports suspension, dissolved organic matter and nitrogen, phosphorus and other nutrients. Currently, there are several ways this treatment process, summed up the main representative of the conventional activated sludge process, oxidation ditch, A / O or A2 / O process, SBR and the CCAS crafts. Currently, there are several representatives of the practical application of technology at home and abroad. Sewage compressor maintenance and maintenance: In order to make the sewage treatment compressor can normally reliable operation, life assurance unit shall develop a detailed maintenance plan, execute fixed-man operation, regular maintenance, periodic inspection and maintenance, so empty Pressure unit kept clean, no oil, no dirt. The main components of sewage treatment compressor maintenance maintenance refer to the following table: cleaning cycles --- A. Must be determined according to the table when the repair and replacement of the components: pressure compressor within the system have been released, has been separated from the other pressure source, switch on the main circuit has been disconnected, and has been allowed to do the closing of the security identity . B. Sewage compressor cooling compressor oil change time depends on the use of the environment, whether acid gas humidity, dust and air. Newly acquired compressor first 500 hours of operation shall be replaced with new oil, after a simple method of sewage treatment to replace the normal oil change every 4000 hours, annual operating less than 4000 hours of machine should be replaced once a year.
