Description
Technical Field
The invention relates to the technical field of rural domestic sewage collection, in particular to an experimental device for verifying the sewage collecting effect of a negative pressure pipeline.
Background
At present, the toilet revolution is implemented in most rural areas in China, and the living environment of the rural areas is improved. However, the existing policy is only to change the water closet to the dry toilet, each household builds a three-format septic tank, and no further solution is provided for how to treat the sewage when the subsequent septic tank is full. Referring to the mature case in the world, there are three solutions according to different rural scales: the first is to connect the infiltration system around the septic tank, make the sewage percolate to the peripheral subsurface, this scheme is suitable for single rural household, national countryside such as Switzerland adopts this kind of method; the second is that the dung sucking vehicle is adopted to suck the dung regularly, and the scheme is suitable for scattered living rural areas; the third scheme is to build a pipe network, connect the septic tank to the pipe network, and collect sewage to a sewage treatment plant through the pipe network, and the scheme is suitable for rural areas with certain living scale. The mode of making sewage flow to the treatment plant by itself by means of gravity requires deep burying of pipelines, the excavation amount is large, the construction cost is high, the negative pressure pipe network does not need deep digging and deep burying, and the construction amount is small, so that the negative pressure pipe network is a feasible scheme.
China has a large population, and the rural scale is much larger than that of countries such as Swiss. In the long term, the construction of a negative pressure pipe network is an effective scheme for solving the problem of rural sewage collection. At present, negative pressure is adopted to collect sewage, public toilets in certain public places also comprise negative pressure toilets used on high-speed rails, the distances between the negative pressure collecting devices of the toilets and the excrement collector are very close, and when the distance of the pipeline is very long, such as 2 kilometers, the negative pressure collecting effect is closely related to a specific embodiment. The theoretical analysis of the negative pressure sewage pipe network has a great deal of literature, the coverage range of the general rural negative pressure pipe network can reach one kilometer in radius, and the established negative pressure collecting system in the range has no report at present. Particularly, the topography of each place in rural areas is different, the topography is uneven in height and different in landform, so that how to arrange a collecting pipe network in reality to ensure the effect of sewage collection needs to be verified by experiments before construction.
Application publication No. CN 109455894A has disclosed rural lavatory septic tank liquid manure and peasant household sewage negative pressure collection system, and application publication No. CN 110158742A has disclosed a negative pressure sewage collection technology, does not all relate to this core problem of how to verify that long distance negative pressure pipeline collects the effect.
The invention can adjust different height differences of each pipeline in a laboratory according to actual rural terrain, simulate the actual rural pipeline laying state, monitor parameter values of each pipeline at any time and aim to verify the effect of negative pressure sewage collection.

The device comprises a water inlet valve 1, a primary filter tank 2, a secondary filter tank 3, a tertiary filter tank 4, a water outlet valve 5, a pressure sensor 6, a vision camera 7, a hard pipe 8, a hose 9, a lifting structure 10, a vacuum tank 11, a vacuum pump 12 and a sewage outlet 13.
Referring to fig. 1, an experimental apparatus for verifying the effect of collecting sewage by a negative pressure pipeline, first, a water outlet valve 5 is in a closed state. The vacuum pump 12 generates a negative pressure of 0.3bar in the sewage pipe formed by the vacuum tank 11, the hard pipe 8 and the hose 9. Sewage flows into a primary filtering tank 2, a secondary filtering tank 3 and a tertiary filtering tank 4 of the three-grid septic tank in sequence through a water inlet valve 1, and when the tertiary filtering tank 4 is full and needs to be drained, a water outlet valve 5 is opened, and under the action of pressure difference, the sewage flows into a vacuum tank 11 through hard pipes 8 and hoses 9 at all sections and then flows into a subsequent sewage treatment plant through a sewage discharge outlet 13. The hard pipe 8 is erected by adopting the lifting structure 10, so that the heights of all sections of hard pipes 8 are different, and the real topography of the rural area is simulated. The terrain with the same height of the buried pipe can be simulated by a hard pipe 8, and the terrain with height difference is connected by a flexible hose 9. A pressure sensor 6 is arranged on the hard pipe 8 or the flexible pipe 9, and the pressure change in the pipeline is monitored in real time. A hard pipe 8 or a soft pipe 9 used in the experimental device is a transparent pipe, a vision camera 7 is installed on the outer side of the pipeline, and the state of fluid in the pipeline can be shot and recorded.
Fig. 2 is a partial schematic view of the experimental apparatus, which mainly expresses that the flexible pipe 9 is connected with the hard pipes 8 with different heights.
Fig. 3 is a schematic view of a lifting device. Comprises a base 101, a travel stop block 102, a cylinder 103 and a semi-annular bracket 104. The hard tube 8 is erected on the semi-annular bracket 104, the cylinder 103 realizes the lifting of the hard tube 8, the height of the travel stop block 102 determines the travel of the cylinder 103, and the travel stop blocks 102 with different heights can be replaced according to different travel requirements.
The height of the hard tube 8 is adjusted by the lifting structure 10, that is, the hard tube 8 is erected on the lifting device 10, and the height position of the hard tube 8 depends on the lifting height of the lifting device 10. For example, a first section of hard pipe is lifted to 3 meters by a first lifting device, a second section of hard pipe is lifted to 8 meters by a second lifting device, the two types of hard pipes with different heights have a height difference of 5 meters, and then the hard pipes are connected by a hose 9, and the plurality of sections of hard pipes 8, the hose 9 and the lifting device 10 form an integral sewage drainage pipeline. The final purpose of the invention is to simulate whether the pipeline with high and low fall which is built in the actual rural area can discharge sewage normally.
For example, during actual testing:
experiment 1: the total height difference of the pipelines is 5 m;
experiment 2: the total height difference of the pipelines is 0 meter, and 3 sections of pipelines in the middle are respectively lifted by 2 meters;
finally, data are obtained through experiments, and a basis is provided for rural negative pressure sewage pipeline arrangement.
