Description
Technical Field
The invention relates to the field of wastewater treatment, in particular to a filtering and recycling process for bathroom wastewater.
Background
Bathroom waste water mainly refers to domestic waste water generated in daily sanitary life such as bathing and washing, and the domestic waste water is usually directly discharged to the outside, but the domestic waste water contains a large amount of pollutants, and the direct discharge causes great damage to the environment. Along with the continuous improvement of people's environmental protection consciousness, people attach more and more importance to the pollution problem of domestic sewage, how to carry out effectual processing to this part domestic wastewater to can reduce the destruction to the environment, waste water reuse even, the water economy resource is the problem that waits to solve now urgently.
Disclosure of Invention
The invention aims to provide a filtering and recycling process for bathroom wastewater, which can effectively remove impurities and harmful substances in the bathroom wastewater, and has the advantages of low energy consumption, stable separation performance and high effluent quality.
In order to achieve the purpose, the invention adopts the technical scheme that:
a filtering and recycling process of bathroom wastewater comprises the following steps: sequentially feeding the bathroom wastewater into a three-stage filter for primary filtration, then feeding the bathroom wastewater into a membrane filter for deep filtration, finally outputting clear liquid after ultraviolet sterilization,
the three-stage filter comprises an activated carbon filter for adsorbing large-particle impurities in the bathroom wastewater;
the bag filter is used for filtering and removing most of solid particulate matters with the particle size larger than 0.1mm in the bathroom wastewater;
the security filter is used for intercepting mechanical impurities with the particle size larger than 5um in the bathroom wastewater;
the membrane filter is a nanofiltration membrane and is used for further removing harmful substances in the bathroom wastewater.
Preferably, after the filtration is finished, the concentrated waste liquid in the membrane filter is discharged, and then the operation is stopped after being continued for 15 s.
Preferably, a pickling solution is prepared and heated, the heated pickling solution is introduced into the membrane filter to be pickled, and after pickling, the pickling solution is discharged.
Further preferably, the heating temperature of the pickling solution is 45 ℃, and the pickling time is 30-45 minutes.
Further preferably, clear water is introduced into the membrane filter to eject the pickling solution remaining in the membrane filter.
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages: according to the filtering and recycling process for the bathroom wastewater, the primary filtering of the three-stage filter is matched with the deep filtering of the membrane filter, and the bathroom wastewater is sterilized and disinfected by using ultraviolet rays, so that impurities and harmful substances in the bathroom wastewater can be effectively removed, the energy consumption is low, the separation performance is stable, and the effluent quality is high.
Detailed Description
The technical solution of the present invention is further illustrated below with reference to specific examples.
The invention relates to an improvement on a recovery process of bathroom wastewater, which can recover a large amount of bathroom wastewater and avoid waste of water resources. This recovery technology, the prefiltration that matches through tertiary filter and membrane filter's deep filtration, uses the ultraviolet ray to disinfect it simultaneously, can effectively get rid of impurity and harmful substance in the bathroom waste water, and the energy consumption is low, and separation performance is stable, and it is high to go out water quality of water.
In the embodiment, a filtering and recycling process of bathroom wastewater is disclosed, which comprises the following steps: and sequentially feeding the bathroom wastewater into a three-stage filter for primary filtration, then feeding the bathroom wastewater into a membrane filter for deep filtration, and finally outputting clear liquid after ultraviolet sterilization.
Wherein, tertiary filter includes, activated carbon filter for adsorb the large granule impurity in the bathroom waste water, in order to prevent the jam of later process.
The bag filter is used for filtering and removing most of solid particulate matters with the particle size larger than 0.1mm in the bathroom wastewater so as to prevent the large particulate matters from entering the nanofiltration membrane.
The security filter is used for intercepting mechanical impurities with the particle size larger than 5um in the bathroom wastewater;
the membrane filter is a nanofiltration membrane and is used for further removing harmful substances in the bathroom wastewater. The special cleaning method of the nanofiltration membrane is utilized, the service life is prolonged, the oil resistance and the pollution resistance are ultrahigh, the bathroom wastewater is treated by matching with the three-stage filter, and meanwhile, the bathroom wastewater is sterilized and disinfected by using ultraviolet rays, so that impurities and harmful substances in the bathroom wastewater can be effectively removed, the energy consumption is low, the separation performance is stable, and the quality of effluent is high.
After the filtration is completed, the concentrated waste liquid in the membrane filter is discharged, and then the operation is continued for 15s, and then the operation is stopped. By the concentration discharge treatment, the residual concentrated waste liquid can be basically discharged. Then preparing pickling solution and heating the pickling solution at the temperature of 45 ℃. And introducing the heated pickling solution into a membrane filter for pickling, wherein the pickling time is 30-45 minutes. And discharging the pickling solution after the pickling is finished. The membrane filter is subjected to acid washing again, so that the acid-base environment in the membrane filter can be effectively adjusted, and the membrane tube is prevented from being corroded.
And finally, introducing clear water into the membrane filter, and ejecting the residual pickling solution in the membrane filter.
The above-mentioned embodiments are merely illustrative of the technical idea and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the scope of the present invention.
