Further, described secondary filter is asymmetrical fibre strainer.
Further, described primary filter box top is provided with cascade filtration net and unpicks and washes door.
Elementary sewage outlet higher than sewage inlet, and arranges cascade filtration net between elementary sewage outlet and sewage inlet, and floating matter effectively can be tackled by cascade filtration net, due to action of gravity, can reduce the blocked situation of filtering net and occur.
Secondary filter adopts asymmetrical fibre strainer, has that filtering velocity is fast, holding filth capacity large, the advantage of easily back flushing.
Primary filter box top is provided with cascade filtration net and unpicks and washes door, when cascade filtration net produces blocking, can re-use after cleaning taken out by cascade filtration net dismounting goalkeeper cascade filtration net.
The utility model compared with prior art tool has the following advantages:
Sewage disposal device of the present utility model is unpowered operation, easy to maintenance, has running cost low, stable feature, and treatment capacity is moderate, is particularly suitable for small displacement sewage disposal and uses.
