Problems solved by technology

At present, most of the research on bathing wastewater reuse treatment technology and equipment in my country focuses on the reuse of reclaimed water, and there is a lack of systematic research on the direct reuse of bathing wastewater. The water quality characteristics of bathing wastewater, especially the pollution indicators in wastewater There are still few studies on the impact of each process link

specific Embodiment approach 1

[0005] Specific embodiment one: an integrated physical and chemical treatment method for reuse of bathing wastewater, which is completed through the following steps: (1) drop into polyferric chloride in wastewater, and carry out coagulation and precipitation; (2) the water after precipitation Filter through anthracite-quartz sand double-layer filter material; (3) filtered water enters the container containing granular activated carbon adsorption column and zeolite ion exchange column for activated carbon adsorption and ion exchange; (4) treated water enters ultrafiltration (5) UV disinfection of water.

specific Embodiment approach 2

[0006] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in the process of coagulation and sedimentation, the dosing ratio is 18-22 mg of polyferric chloride per liter of waste water, and the precipitation time is 10-17 minutes. Preferably, 20 mg of polyferric chloride is added per liter of wastewater, and the precipitation time is 15 minutes. Other steps are the same as those in Embodiment 1.

specific Embodiment approach 3

[0007] Specific implementation mode three: the following combination figure 1 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is that in step (2), the quartz sand 2 with a particle size of 0.9 to 1.2 mm and the anthracite 1 with a particle size of 1.5 to 2 mm form an anthracite-quartz sand double-layer filter material, The precipitated water passes through the filter material at a filtration speed of 10-15 m / hour. Other steps are the same as those in Embodiment 1.

Abstract

The method includes five processes: put the 'Fecl2' into the waste water then the foreign matter will precipitate; the suspend water will flow into the two-double filer material of anthracite-quartzite to filter; the export water flow in the sorption column of activiated carbon and the ion exchange column of zeolite; next the water flow through the super filer membrane to filter; last the water is disinfected in the UV. The whole process is compose of independent units. It can be controlled easily and it have highly practical value because of the advance in the economy and technology.

Description

Technical field: [0001] The invention relates to a physical and chemical treatment method for bathing wastewater, through which most of the pollutants in the bathing wastewater can be effectively removed, and the water quality standard for bathing reuse can be achieved. Background technique: [0002] Due to the continuous shortage of water resources, how to improve the utilization rate of existing water resources has become a major research topic in the field of water treatment. The bathing industry is a large urban water consumer, and the daily water consumption of a medium-sized bathing pool can reach hundreds of tons. Taking Harbin as an example, 600,000 of the city's population of 9.5 million take baths every day, and the average bathing water consumption per person is 0.2m 3 Calculated, the daily bathing water volume is 120,000 m 3 , with an annual water consumption of 44 million m 3 . Factories, coal mines and other industrial enterprises, hotels and other places w...
