a composite functional biomembrane sewage filtering tank consists of a sewage level pressure tank, a biomembrane filtering tank and a slag discharging tank; the device is arranged in a heat-preservation greenhouse, the sewage level pressure tank is communicated with the biomembrane filtering tank through a water inlet of the biomembrane filtering tank, the front end of the bottom of the biomembrane filtering tank is higher than the rear end of the bottom of the biomembrane filtering tank, and a plurality of filling ports and a methane outlet are arranged on the tank cover of the biomembrane filtering tank; baffle walls for increasing flow and preventing short circuit are arranged in the biological membrane filter tank, and a water outlet is reserved between each baffle wall and the left side or the right side tank wall; the bottom of the biomembrane filtering pond is provided with a heater to increase the temperature of the biomembrane and improve the digestion efficiency; the pool is filled with plant materials; the rear end of the biomembrane filter tank is communicated with the deslagging tank through a deslagging port, the deslagging port is provided with a filter grid, and the rear part of the deslagging tank is connected with a filtered water pre-storage tank through a filtered water outlet and a filtered water overflow channel.

The plant material is corn cob.

The two sides of the tank cover of the biological membrane filtering tank are provided with filling openings in a sectional manner, and the middle of the tank cover is provided with a plurality of methane outlets.

As a biomembrane zone, anaerobic flora is generated under anaerobic conditions, and the suspended matters and soluble organic matters are retained for digestion and conversion when sewage passes through, thereby achieving the purpose of sewage treatment.

The utility model has the advantages that: 1. the biomembrane filtering ponds that this device set up filter and biological reaction unite two into one, form a combined treatment function, and this cell body is the airtight mode of water-stop, and inside has multichannel baffling wall to increase sewage flow and biological action time, prevent the flow short circuit, this facility area is little, and the handling capacity is big, arranges the assurance that is favorable to ambient temperature in the big-arch shelter in, just also is favorable to guaranteeing sewage treatment's temperature requirement.

2. Plant materials (corncobs and the like) are filled in the tank as filter media, then an 'anaerobic biomembrane zone' is formed under anaerobic conditions, suspended matters are intercepted when sewage passes through, and meanwhile various pollutants (saccharides, lipids and ammonia nitrogen) in the sewage are absorbed and converted by the 'anaerobic biomembrane zone' of hundreds of thousands of square meters, so that the aim of purifying the sewage is fulfilled. The technology makes the low-cost treatment of the urban domestic sewage possible.

3. The composite function filter tank is formed by compounding the filtering function and the anaerobic digestion function, so that the functions are increased, the investment is reduced, the step-by-step and multi-channel processes are unified, the operation is more stable, and the efficiency is higher.
