Detailed Description
The invention is further described with reference to the following drawings and detailed description.
Before the technical scheme of the invention is introduced, the principle and the structure of a three-stage septic tank which are common in the field are introduced.
In a general case, a three-stage septic tank is one of septic tanks. And the sewage is bent upwards from the middle part of the primary pond through a pipeline and enters the next primary pond for secondary purification, and then the sewage subjected to secondary purification is guided into the next primary pond for secondary purification, so that the sewage is completely purified into water after being subjected to tertiary purification, and the sewage can flow into a sewer to be guided to a sewage treatment plant and finally flows into a river.
The working principle is as follows: fresh excrement enters the first tank from an excrement inlet, the excrement in the tank starts to ferment and decompose, and liquid excrement can be naturally divided into three layers due to different specific gravities, wherein the upper layer is pasty excrement skin, the lower layer is blocky or granular excrement slag, and the middle layer is relatively clear liquid excrement. Bacteria and parasitic ova are contained in the upper layer of excrement skin and the lower layer of excrement slag, the number of ova contained in the middle layer is the least, the middle layer of excrement liquid after primary fermentation overflows to the second tank through the excrement pipe, and most of excrement skin and excrement slag which are not fully fermented are retained in the first tank for continuous fermentation. The liquid dung flowing into the second pool is further fermented and decomposed, worm eggs continue to sink, pathogens die gradually, the liquid dung is further harmless, and the thickness of the generated dung skin and the dung is obviously reduced compared with that of the first pool. The liquid manure flowing into the third tank is typically already decomposed, wherein pathogenic bacteria and parasitic eggs are substantially killed. The third tank functions mainly to store the essentially harmless liquid manure.
The three-stage pool can be prefabricated by using brick cement powder wall surfaces or cement cast-in-place, and can be in a shape like a Chinese character 'mu' or 'Ding', if the three-stage pool is limited by terrain, the three-stage pool can be put in a shape like a Chinese character 'pin' or 'Ding'. The volume of the excrement is preferably 2 months. The effective depth of the third-stage pool is not less than 1m, and the volume ratio of 1-3 stages is generally 2: 1: 3.
Generally speaking, the three-stage septic tanks mentioned in the prior art are all static environments, the size of the inner space cannot be adjusted, the whole septic treatment process is a slow static degradation process, the degradation efficiency is extremely low, the finally flowing water is generally low and only barely meets the discharge standard, and the resource utilization cannot be carried out.
Particularly, in rural areas in the northern part of China, part of rural areas in the northern part of China have no sewage treatment facilities, and a vehicle is required to be used for extracting excrement in the septic tank regularly for centralized disposal. The concentration of the extracted excrement is often extremely low, so that the transportation efficiency is not high, and the operation cost is high.
Based on this, various embodiments of the technical solution of the present invention are introduced.
Referring to fig. 1, the overall appearance of a concentrated liquid dung storage device for northern rural areas is schematically shown according to an embodiment of the present invention.
In fig. 1, a concentrated storage facility for fecal sewage in northern rural areas is shown, said facility comprising a facility body 1 and a facility roof 2; the device body 1 is provided with a manure inlet 11 and a water outlet 12,
a plurality of partition plates 13, 14 and 15 are arranged between the manure inlet 11 and the water outlet 12, and the partition plates 13, 14 and 15 divide the inner space of the equipment body 1 into a plurality of subspaces 16, 17 and 18;
the plurality of subspaces comprises a first sedimentation fermentation tank 16, a second filtration tank 17, a third clarification tank 18 and a fourth distillation tank 19;
the equipment top plate 2 is a one-way tempered glass cover plate, and the one-way tempered glass cover plate covers the plurality of subspaces 16, 17 and 18;
the glass cover plate is set to be an one-way toughened glass cover plate, and the glass cover plate not only can play a role in transmitting sunlight, but also can play a role in shielding (shielding the outside from seeing the sight inside the septic tank).
The cover heights of the plurality of subspaces 16, 17 and 18 are covered by the one-way toughened glass cover plate, and the cover heights are sequentially reduced along the first sedimentation fermentation tank 16, the second filter tank 17, the third clarification tank 18 and the fourth distillation tank 19;

In order to change the problem that the static environment of the three-stage septic tank of the prior art causes the low treatment efficiency, in the technical scheme of the present invention, the first partition plate 13 and the third partition plate 15 may be shaken within a predetermined range, and the shaking is slight shaking.
The inventors have found that in a long-term static (almost) closed environment, regular slight shaking and changes in the size of the subspace can disturb the entire process flow, thereby changing the process efficiency, and that proper arrangement of the position of the shaking can accelerate the process efficiency.
To this end, the invention is further improved in a number of respects.
On the basis of fig. 1, further reference is made to fig. 2.
The bottoms of the first sedimentation fermentation tank 16, the second filtering tank 17 and the third clarification tank 18 are respectively provided with plain concrete backfill slope layers 161, 171 and 181;
the first gradient 160 of the plain concrete backfill gradient layers 161, 171 and 181 is smaller than the second gradient 20 of the equipment top plate 2 relative to the horizontal plane.
The equipment top plate 2 is provided with a solar energy storage device 21;
in one aspect, the first partition plate 13 between the first sedimentation fermentation tank 16 and the second filtration tank 17 is rockable within a first predetermined range 162 where the plain concrete backfill slope layer 171 arranged at the bottom of the second filtration tank 17 is close to the top of the slope;
an exhaust hole 22 is arranged in the area where the top plate 2 of the device covers the first sedimentation fermentation tank 16;
the exhaust hole 22 is connected with a micro monitor 23, and the micro monitor 23 is used for monitoring the components and the concentration of the gas exhausted from the exhaust hole 22;
the power is supplied to the micro monitor 23 through the solar energy storage device 21, and the first partition plate 13 is controlled to shake within the first predetermined range 162 based on the monitoring result of the micro monitor 23.
In another aspect, the third partition 15 between the third clarifier 18 and the fourth distillation tank 19 is rockable within a second predetermined range 182 near the bottom of the slope of the plain concrete backfill slope layer provided at the bottom of the third clarifier 18;
a water level meter 191 is arranged in the area of the top plate 2 of the device covering the fourth distillation pool 19;
the third partition 15 is controlled to swing within the second predetermined range 182 by the water level measurement result of the water level meter 191.
A schematic of the shaking can be seen in fig. 3.
The solar energy is used for controlling the shaking of the partition plate, so that the subspace environment in the whole three-stage septic tank slightly shakes according to a preset period or preset conditions, the defect of the prior art that the subspace environment is always static is overcome, the fecal sewage can be better treated, and the efficiency of collecting, depositing, filtering and evolving the fecal sewage is improved; meanwhile, the shaking is only slight shaking, and too much energy is not needed, so that the energy-saving and consumption-reducing effects can be realized by utilizing external solar energy.
It should be noted that the shaking needs to be executed when a preset period or a preset condition is met, so the frequency of the actual execution process is not very high, and the design has enough solar energy in view of the good illumination condition in northern rural areas, which is also proved by the practical application scenario.
In the above embodiment, the apparatus body 1 is placed on the composite cushion layer 3; the composite cushion layer 3 comprises two layers, namely a plain concrete cushion layer 31 and a sandstone cushion layer 32 from top to bottom.
Fig. 4 is a schematic view of an actual installation scenario of the fecal sewage concentrating and storing apparatus shown in fig. 1 or fig. 2.
Referring to fig. 4, a sewage concentration and storage device in rural areas in the north is provided with a distillation tank on the basis of a three-stage septic tank, and agricultural sewage in the septic tank is distilled into the distillation tank through sunlight (a unidirectional toughened glass cover plate is arranged on the septic tank). Not only can concentrate rural sewage, but also can carry out resource utilization on the treated water. The specially-arranged unidirectional toughened glass can not only transmit sunlight, but also play a role in shielding, and can shield the sight of the inside of the septic tank from the outside.
In fig. 4, the first sedimentation fermentation tank 16, the second filtration tank 17 and the third clarification tank 18 are respectively a primary sedimentation fermentation tank, a secondary filtration tank and a tertiary clarification tank.
According to the respective realization effects, the method can be realized by adopting the existing sedimentation fermentation tank, the filter tank and the clarification tank in the prior art, and the invention does not develop the method.
