Abstract

The present invention relates to a staged multistep multiple-biota sewage treatment method. In a tractional flow type bio-chemical tank several groups of vertically-arranged baffle plates are mounted, said bio-chemical tank is separated into several insulated chambers, every insulated chamber can be formed into relatively-independent pu-flowed reactor, several up-flowed reactors are series-connected together and formed into the invented system process, along said system process the anaerobic or facultative anaerobic-aerobic treatments can be continuously and alternatively operated, so that the microorganism can be fully separated. Said invention also provides its main technological parameters; maximum COD volume load is 28 kg CODcr/cu.m.d, and maximum NH3-N volume load is 3.0 KgNH3-N/cu.m.d.

Description

Technical field [0001] The invention relates to a sewage biological treatment method, in particular to a phased, multi-stage, and multi-biological sewage treatment method. Background technique [0002] There are two main types of sewage biological treatment methods: anaerobic biological treatment methods and aerobic biological treatment methods. In practical applications, anaerobic treatment methods and aerobic treatment methods are usually combined. At present, among the processes that combine anaerobic and aerobic treatment methods, the most representative process is the A / O method, also known as the pre-denitrification process. The A / O method has many advantages such as high sewage treatment capacity, good effluent quality, and mature technology. In addition to removing organic pollutants (BOD 5 ) In addition, it can also remove part of plant nutrients such as ammonia, nitrogen and phosphorus at the same time, so it has been widely used in the field of sewage treatment. But at...
