4. the governing system of rural area black and odorous water and waste according to claim 1, it is characterised in that: the biomembrane Filter tank refers to biological rotating disk biofilm biochemical reactor or submergence lifting circulating biological membrane filtration pond；The submergence Go up and down circulating biological membrane filtration pond, using etc. weights two groups of symmetrical interlaced arrangements filter curtain.

5. the governing system of rural area black and odorous water and waste according to claim 1, it is characterised in that: the fiber filter Pond is symmetrical arranged filter hole using round-trip drawing-in type fibre filter between cesspool and reservoir, installs in filter hole solid Surely there is filter plate, the sewage in cesspool enters reservoir by the filtering of filter plate, sets in the cesspool side of filter plate It is equipped with ooze sucker, ooze sucker does lifting under the action of the driving mechanism or the synchronous backward of transverse direction inhales mud movement, when filter plate goes out When now blocking, the liquid level of cesspool sewage rises, when cesspool sewage level reaches the liquid level of liquid level sensor setting, automatically controlled system System control starting ooze sucker carries out back suction suction to the sludge on filter plate, and starts driving mechanism simultaneously and ooze sucker is driven to go up and down Or lateral synchronous backward inhales mud displacement, and the sludge suction on filter plate is walked, filter plate is made to restore filter capacity again.
