Embodiment Construction

[0021] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 , a kind of rural sewage strengthened composite anaerobic treatment device of the present invention adopts multi-stage anaerobic operation, comprises anaerobic baffle plate reaction zone 100 and multi-media combination anaerobic biological biological filter zone 200, the volume ratio of the two can be 3 : 2; Wherein, the multi-media combined anaerobic biological biological filtration zone 200 is located below the anaerobic baffle reaction zone 100.

[0023] The anaerobic baffle plate reaction zone 100 is used to remove suspended matter and part of dissolved organic matter in sewage. Its interior is divided into multiple compartments by deflectors, among which the first few compartments are upflow suspended sludge bed reaction compartments 1, and different dominant microorganisms are formed in each upflow suspended slud...

Abstract

The invention discloses a rural sewage enhanced composite anaerobic treatment device and a treatment method. The treatment device comprises an anaerobic baffle reaction zone; the interior of the anaerobic baffle reaction zone is divided into a plurality of up-flow type suspended sludge bed reaction compartments and a sludge settling compartment by guide plates; the upper part of the up-flow type suspended sludge bed reaction compartments is filled with a composite fiber filler, and microporous aeration heads are formed at the bottom of the up-flow type suspended sludge bed reaction compartments; the treatment device further comprises a multi-media combined anaerobic biological filtration zone communicated with the sludge settling compartment; and the interior of the multi-media combined anaerobic biological filtration zone is filled with an active lightweight biological filler, and up-flow type water distribution is adopted for secondary treatment of settled sewage. The method for treating sewage by adopting the device comprises the following steps: the rural sewage enters the anaerobic baffle reaction zone, suspended matter and partial dissolved organic matter in the sewage are first removed through the up-flow type suspended sludge bed reaction compartments, and then the sewage flows into the sludge settling compartment, after most of the sludge is deposited, the sewage flowsinto the multi-media combined anaerobic biological filtration zone to further remove the dissolved organic matter.

Description

technical field [0001] The invention relates to a sewage treatment device and a treatment method, in particular to a rural sewage enhanced composite anaerobic treatment device and a treatment method, belonging to the technical field of water treatment. Background technique [0002] Conventional anaerobic treatment technologies for rural sewage include anaerobic biofilters, upflow anaerobic sludge bed reactors, and anaerobic baffle reactors. Among them, the anaerobic biological filter for treating rural sewage is easy to block, the treatment efficiency is not high, it is not suitable for the treatment of sewage with high suspended solids, and the filter takes a long time to start; the sludge granulation in the upflow anaerobic sludge bed reactor has a great impact on The process requirements are strict, the two phases are difficult to separate, the sludge is easy to lose, the reactor is prone to short-flow phenomenon, and the mud and water cannot be fully mixed; the anaerobic...
