Description
The technical field is as follows:
the utility model belongs to the technical field of waste water treatment, concretely relates to city life washing effluent disposal system.
Background art:
the urban domestic sewage comprises cooking water in a kitchen, washing wastewater and excrement wastewater, and the conventional treatment process is that the three types of wastewater are generally discharged into an urban sewage treatment plant through the same pipe network and then are treated by the sewage treatment plant and then are discharged or recycled. On-site investigation finds that two pipelines are arranged in a corridor, one pipeline is a toilet pipeline, and excrement wastewater and washing wastewater are discharged into a sewage pipeline together; the other is a kitchen sewage pipeline. The two sewage pipelines are finally converged into the same sewage pipe network and then discharged into different sewage treatment plants for treatment according to regional separation. The wastewater treatment capacity is large, and classification treatment is not performed according to the characteristics of wastewater.
The washing wastewater in the urban domestic wastewater is generated in the washing processes of bathing, tooth brushing, face washing, clothes washing and the like of people, and the wastewater contains a large amount of washing and chemical products, such as toothpaste, laundry detergent, facial cleanser, shower gel and the like. The main components of the washing and chemical product comprise a surfactant, a conditioner, a thickening agent, a functional auxiliary agent and the like, so that the material components of the waste water are relatively single and easy to treat. The washing wastewater can be directly used for flushing the toilet, and the wastewater contains impurities and is easy to generate foam, so that the direct use causes sensory discomfort. The other important reason is that the washing wastewater needs to be collected and stored firstly, so that the problem of asynchronous generation of the washing wastewater and use of toilet flushing water is solved. Therefore, the invention designs an urban domestic washing wastewater circulating system.
The utility model has the following contents:
the utility model aims to overcome the defects existing in the prior art and seek to design a city domestic washing wastewater treatment system, thereby solving the problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a city washing wastewater circulating system comprises a first pipeline, a washing wastewater treatment device and a second pipeline, wherein the washing wastewater treatment device comprises a fine grid, an adjusting tank, a filter, an ozone catalytic oxidation device and an ultrafiltration device, activated carbon oxide and double-metal hydroxide are sequentially filled in the filter from bottom to top to form an activated carbon layer and a double-metal hydroxide layer respectively, the fine grid is communicated with a water inlet of the adjusting tank, a water outlet of the adjusting tank is communicated with a water inlet at the bottom of the filter, a water outlet at the top of the filter is communicated with the ozone catalytic oxidation device, and the ozone catalytic oxidation device is communicated with a water inlet of the ultrafiltration device; the user washing wastewater inlet is connected with a tap water supply pipeline, the user washing wastewater outlet is connected with the water inlet of the washing wastewater treatment device through a first pipeline, the water outlet of the washing wastewater treatment device is connected with the water inlet of a user closestool/urinal through a second pipeline, and the water outlet of the user closestool/urinal is connected with a sewage discharge pipeline of a sewage treatment plant.
Compared with the prior art, the utility model following beneficial effect has: (1) by circulating the washing wastewater in space, the problem that the generation of the washing wastewater and the use of the toilet flushing wastewater are asynchronous is solved; (2) through simple circulation and treatment, the waste water can be washed for flushing a toilet, the utilization rate of water is improved, and the treatment burden of a sewage treatment plant is reduced.
Description of the drawings:
FIG. 1 is a schematic view of the municipal domestic washing wastewater treatment system according to example 1.
FIG. 2 is a schematic view showing the structure of a washing wastewater treatment apparatus according to example 1.
The specific implementation mode is as follows:
the present invention will be further described with reference to the following specific embodiments and accompanying drawings.
Example 1:
as shown in fig. 1, an urban washing wastewater circulating system comprises a first pipeline 2, a washing wastewater treatment device 3 and a second pipeline 4, wherein the washing wastewater treatment device comprises a fine grid 12, an adjusting tank 7, a filter, an ozone catalytic oxidation device 10 and an ultrafiltration device 11, activated carbon oxide and bimetallic hydroxide are sequentially filled in the filter from bottom to top to respectively form an activated carbon layer 8 and a bimetallic hydroxide layer 9, the fine grid 12 is communicated with a water inlet of the adjusting tank 7, a water outlet of the adjusting tank 7 is communicated with a water inlet at the bottom of the filter, a water outlet at the top of the filter is communicated with the ozone catalytic oxidation device 10, and the ozone catalytic oxidation device 10 is communicated with a water inlet of the ultrafiltration device 11; the user washing wastewater inlet is connected with a tap water supply pipeline 1, the user washing wastewater outlet is connected with the water inlet of a washing wastewater treatment device 3 through a first pipeline 2, the water outlet of the washing wastewater treatment device 3 is connected with the water inlet of a user closestool/urinal through a second pipeline 4, and the water outlet of the user closestool/urinal is connected with a sewage discharge pipeline 5 of a sewage treatment plant.
The washing wastewater treatment device 3 can be arranged in a community or a sewage treatment plant and is specifically adjusted according to actual needs. In addition, the second pipe 4 is also connected to the tap water supply pipe 1 to supplement the washing wastewater with insufficient reuse water.
As shown in fig. 1, the washing wastewater generated by the building users a to D flows into the first pipe 2 from the washing wastewater outlet thereof, and is transported to the washing wastewater treatment apparatus 3 via the first pipe 2. The method comprises the steps of firstly filtering solid matters such as hair and sebum scraps in wastewater through a fine grating 32, then sending the solid matters into an adjusting tank 31 to adjust the pH value to be neutral, then entering a filter 33 from the bottom of the filter, sequentially passing through an activated carbon filter layer 331 and a bimetal hydroxide filter layer 332 to remove organic matters for the first time, particularly adsorbing a surfactant, then entering an ozone catalytic oxidation device 34 to remove the organic matters for the second time, filtering effluent of the ozone catalytic oxidation device through an ultrafiltration device 35, returning the effluent to a second pipeline, and delivering the effluent to a user through the second pipeline 4 for the flushing. The user excrement flushing wastewater is directly conveyed to a sewage treatment plant through a sewage discharge pipeline 5 of the sewage treatment plant for treatment.
