Continuation is referring to Fig. 1, Fig. 2, and the solid-liquid separator 5 among the present invention comprises cylindrical shell 51 and inserts the intravital sewage water inlet pipe 52 of tube, sewage water inlet pipe 52 external sanitary sewage house stewards.Be provided with one conical baffledly 53 in the cylindrical shell below sewage water inlet pipe 52, be provided with solid dirt discharging mechanism 54, can irregularly discharge the solid dirt in the solid-liquid separator 5 as required in cylindrical shell 51 lower ends.

Continuation is referring to Fig. 1, Fig. 2, circularly purifying mechanism 6 among the present invention comprises recycle pump (not shown), strainer (not shown), magnetic valve 61 and corresponding connecting tube, recycle pump is arranged on and purifies in the bucket 4, and its water inlet pipe deeply purifies the bottom of bucket 4, carries out circularly purifying with the water that extracts the bottom.Strainer is arranged on the top that purifies in the bucket 4, has been filled with the material of filtration and decolorization in the strainer, water filtration and decolouring in the purification bucket 4 that recycle pump can be taken out, circularly purifying.Magnetic valve is arranged on and purifies between bucket and the solid-liquid separator 5, links to each other with recycle pump with corresponding pipeline by threeway, and is communicated with solid-liquid separator by pipeline.Its working cycle is set by electric apparatus control apparatus, and in the water cycle of circularly purifying mechanism 6 in purifying bucket 4, also the portion water that will purify barrel 4 bottoms by magnetic valve is extracted into solid-liquid separator 5, carries out the systemic circulation of whole device.

The sewage water inlet pipe of Small sewage recycling treatment plant of the present invention links to each other with the sanitary sewage house steward, by pump sewage is pumped into solid-liquid separator 5 in this device, inorganics in the sewage is carried out precipitate and separate, and the organism of high density carried out the anaerobic treatment in early stage, sewage after solid-liquid separation flows into the oxygen bucket 2 of holding concurrently through the outlet C on solid-liquid separator top, and solid dirt is then irregularly discharged by solid dirt discharging mechanism 54 as required.

Sewage is after the water that hold concurrently oxygen bucket 2 and reactor pump into converges effect, outlet A inflow reactor 1 by the oxygen bucket bottom of holding concurrently, in reactor 1, because the effect of aerator 13, the inner/outer tube of reactor 1 produces differential water pressures, make floating stuffing 14 in the reactor 1 with current at reactor 1 internal recycle, cause gas, liquid, microorganism three-phase thorough mixing in the reactor 1 thus, and make and form different dissolved oxygen zones in the reactor 1, cause anaerobism, anoxic, aerobic different zones, reach the purpose of removing organic pollutant and denitrogenation dephosphorization.Floating stuffing 14 tools have the dimensions, and available graticule mesh is held back, and avoid running off with water outlet, need not to establish in addition separating filler and discharging device, and its special structure can be avoided microbial film to be subjected to direct hydraulic shear and come off.After aged mud came off from filler, the blowdown mechanism by reactor bottom intermittently discharged, and regulates sludge loading to adapt to different processing requirements than being easier to.Reactor combines with double oxygen bucket, has strengthened the effect of synchronous nitration and denitrification.Because the aerobic and autotrophy characteristic of nitrifier is obviously different with the anoxic and the different oxygen characteristic of denitrifying bacteria, common denitrification process needs independently to carry out in two reactors, perhaps in a reactor, carry out in turn by the time, rather than spatially cause aerobic or anoxic condition, constantly be in aerobic, anoxic alternative state, therefore do not possess the condition of biological phosphate-eliminating.The combination of reactor of the present invention and double oxygen bucket, making aerobic zone in the reactor is that the autotrophy nitrifier of purpose is a superiority bacteria spp with nitrated, and the aerobic area of the oxygen bucket of holding concurrently is superiority bacteria spp with degradation of organic substances with carrying out denitrifying heterotrophic bacterium, make microbial film not only in time, and spatially alternately be in aerobic, anoxic alternative state, make floating stuffing and active sludge that two classes bacterial classification of different nature (nitrifier and denitrifying bacteria) is worked simultaneously, form synchronous nitration and denitrification, denitrification dephosphorization technique is simplified more, and efficient improves greatly, has reduced hydraulic detention time significantly.

Sewage purifies bucket 4 by reactor 1 top with purifying entering communicating pipe 7 of bucket 4 tops after reactor 1 is handled, in purifying bucket 4, sewage under the effect of circularly purifying mechanism 6 constantly on current downflow.The existence of ball owing to wander about as a refugee, sewage are when wandering about as a refugee ball, and the ball internal resistance is big, and flow velocity is slow, and flow velocity is very fast relatively between ball, and the organism in the sewage, solid substance are moved in the slow ball of wandering about as a refugee of flow velocity by the fast place of flow velocity, and assemble therein.Through becoming hundred times move and assemble, realized that further organism, solid substance separate the effect of promptly wandering about as a refugee with water in the flow process.During running is flowed, by repeatedly replacing of aerobic and anaerobic state, organism is decomposed fully, no mud is piled up in the purification bucket.Circularly purifying mechanism 6 also has purification function except that having circulatory function, strainer wherein having decolouring and going the effect of distinguishing the flavor of, increasing water quality.

The water outlet B of treated water through purifying bucket 4 bottoms flows into the bottom of polishing filter 3 in purifying bucket 4, through swash plate 33 bafflings upwards, after behind film filter 32 filtration, purifications, discharged by clear water water outlet 321, sends into little water tank storage as domestic water.Film filter 32 has adopted the negative-ion fiber film, is a kind of textile materials of complex functionization.The functive constituent element is selected a kind of crude tourmaline and an amount of titanium aluminum oxide ceramics powder, and the matrix constituent element is polyester or polypropylene.That this matrix material is better than is single, only contain the material of a kind of main functionality and unstable attach feature, and has higher thermodynamic stability, biologically stable and self-cleaning ability.Behind this combination of materials, mix the moulding of reeling off raw silk from cocoons melting under the body state, use polyester or polypropylene to be base unit simultaneously, but become the negative-ion fiber film of good, the functional lasting repetitive scrubbing of application performance.The negative-ion fiber film is an atmospheric pressure state when work, realizes solid-liquid separation by tubular membrane, has guaranteed that the suspended solids of water outlet is up to standard.
