Description

Circle concrete type waste disposal plant

Technical field

The utility model belongs to technical field of sewage, is specifically related to a kind of round concrete type waste disposal plant.

Background technology

At present, " three forms " septic tank that tradition adopts carries out sewage disposal, and this waste disposal plant is poorly sealed, is unfavorable for the growth of anerobe; Be shaped as the square dead angle of easily staying; And this structural cost height, the installation inconvenience; Limited by landform, bearing capacity is little, and the cycle of drawing clearly is short; Utilize big, the water turbidity of fecal sewage peculiar smell after this technical finesse, every technical indicator does not all reach the state sewage emission standard requirement.

Summary of the invention

At the problems referred to above, the purpose of this utility model provides a kind of round concrete type waste disposal plant, and through the sewage that this treatment unit was handled, the water quality of its processing is transparent, and every technical indicator all reaches the state sewage emission standard requirement.

In order to achieve the above object, technical solution adopted in the utility model is that described round concrete type waste disposal plant is formed by regulating control pond, anaerobism filtrate pond, hydrolysis septic tank and aerobic ventilation pond successively; Be provided with the worker shape pipe parallel with the axis of rotation in pond at adjusting control Chi Wushuirukouchu; Top in anaerobism filtrate pond is provided with the media filtration layer, and the middle part is the digestion chamber, places multiple filtrate, and anaerobion is attached on pool wall and the filtrate, is provided with circular dividing plate in the bottom in pond, and circular dividing plate is provided with many circular apertures; In the hydrolysis septic tank, be provided with dividing plate, the particle valve body is housed on the dividing plate, form the multilayer anaerobic expanded bed.

Described adjusting control pond, anaerobism filtrate pond, hydrolysis septic tank and aerobic ventilation pond are to be formed by reinforced concrete prefabricated, and the Chi Tichi lid is one.

Be provided with cross partitions in the central authorities that regulate the control pond, it is made of two dull and stereotyped square crossings that are trapezoidal shape wide at the top and narrow at the bottom.

The media filtration layer in described anaerobism filtrate pond is made of the biological treatment structures that rubble or plastics filler constitute.

Because the utility model has been taked technique scheme, sewage removes big foreign material through grid filtration, enter adjusting control pond and carry out the adjusting of sewage water quantity and quality, water outlet is further carried out purifying treatment through to anaerobism filtrate pond under the microbial process that filler adheres in anaerobism filtrate pond.Sewage is its water inlet after treatment: COD 912-946mg/L, BOD 335-361 mg/L, SS 2370-2570 mg/L.Water outlet: COD 42.8-61.1mg/L, BOD 11.1-14.3 mg/L, SS 66-75 mg/L.This result is better than the secondary standard value of integrated wastewater discharge standard.

The utility model can both satisfy the strictest environmental requirement in various places in any season, do not produce secondary pollution, microorganism can rely on the organic matter growth in the filler, need not add nutrition agent in addition, it is big to regulate control pond buffer capacity, can regulate the concentration peak automatically and make microorganism works better all the time, the ability of anti impulsion load is strong, and the operation employing is unpowered banishes automatically, highly stable, need not manual operation and maintenance, the pond body adopts the moulding of assembly type concrete, is convenient to transportation and installs.

Description of drawings

Below in conjunction with drawings and Examples structure of the present utility model is described further.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the utility model sewage treatment process figure.

In the accompanying drawing, the control pond is 2. regulated on 1. ground, 3. anaerobism filtrate pond, 4. hydrolysis septic tank, 5. aerobic ventilation pond, 6. media filtration layer, 7. dividing plate.

Embodiment

Referring to Fig. 1, round concrete type waste disposal plant described in the utility model is formed by regulating control pond 2, anaerobism filtrate pond 3, hydrolysis septic tank 4 and aerobic ventilation pond 5 successively; Be provided with the worker shape pipe parallel with the axis of rotation in pond at adjusting control 2 sewage inlet places, pond, to lower the surging force of ight soil, make in the pond liquid stream stable, under action of gravity, the scum silica frost come-up, sediment sinks, central authorities in the pond are provided with the cross partitions (not shown), it is made of two dull and stereotyped square crossings that are trapezoidal shape wide at the top and narrow at the bottom, under the effect of liquid manure mobilization force, liquid manure and cross partitions bump, the liquid manure rotation, friction is pulverized, and solid matter sinks rapidly, the liquid of preliminary clarification enters anaerobism filtrate pond by the feces outlet of certain altitude, stops scum silica frost and sediment to pass through simultaneously; Top in anaerobism filtrate pond 3 is provided with media filtration layer 6, to the fecal sewage filtration, the anaerobion that adheres on it carries out anaerobic digestion to the organism in the liquid dung simultaneously, the middle part is the digestion chamber, place multiple filtrate, anaerobion is attached on pool wall and the filtrate, liquid dung by the time just can fully contact with microorganism and decompose, the methane that produces of anaerobic digestion wherein, carbonic acid gas, gases such as hydrogen sulfide, vapor pipe by the top, pond is discharged, be provided with circular dividing plate (not shown) in the bottom in pond, circular dividing plate is provided with many circular apertures, and its effect both can keep liquid manure stable, contact with anerobe equably, can prevent scum silica frost come-up obstruction filter membrane again, after liquid manure enters in the pond, form top-down vertical-flow flow, enter the hydrolysis septic tank with the liquid dung of digestion from the liquid discharge pipe at top after filtration and proceed degradation treatment.In hydrolysis septic tank 5, be provided with dividing plate 7, the particle valve body is housed on the dividing plate 7, form the multilayer anaerobic expanded bed, microbial film is formed by anaerobion in its surface, fecal sewage by the time continued the anaerobic digestion effect, further the fecal sewage of anaerobic digestion forms top-down flowing, and liquid enters the discharging of ventilation pond by lower nozzle, thereby reaches the sewage disposal purification effects.
