Description
Technical Field
The utility model relates to a water treatment device, in particular to a concentrated water recycling system of a pipeline direct drinking water system and the pipeline direct drinking water system.
Background
Along with the development of economy in China and the improvement of living standard, the demands of people for healthy water are gradually improved, and the application of the safe pipeline direct drinking water system for living drinking water is gradually wide. A common treatment process for producing direct drinking water is a membrane treatment process, and the selection of a membrane directly affects the quality of the treated water. Common membrane processes (precision from low to high) in the market are ultrafiltration, nanofiltration and reverse osmosis, wherein reverse osmosis occupies a relatively high ratio. In the process, most of concentrated water is synchronously generated, and the concentrated water cannot be drunk, and is generally considered to be discharged into a water collection pit and then discharged into a municipal pipe network after being lifted, so that a large amount of high-quality concentrated water (wastewater) is wasted. The current water yield of different direct drinking water treatment processes is different, for example, the water yield of the nanofiltration process is generally 70-85%, and the water yield of the reverse osmosis process is only 60-75%. For a 3000 person office building, about 6 tons of direct water are required per day, while about 4 tons of concentrate (60% water production) are produced. Typically, the concentrate is discharged directly, which results in waste of water resources. The concentrated water can be used for outdoor greening irrigation (2000 m for supply) 2 Green land use) or road watering (available for 2000m 2 Road use), etc., the water consumption can be saved by about 1080 tons (calculated according to working days) each year.
The recycling and utilizing rate of the concentrated water of the direct drinking water of the pipeline is extremely low. The main reasons are two: firstly, treatment equipment, a reuse water supply pipeline and the like are required to be arranged separately, so that the initial investment construction cost is high, and the investment recovery period is overlong; second, the amount of concentrate that can be recovered is much less than the amount of water used in the building, which results in people neglecting this part of the water recovery. Some technicians consider collecting the concentrate directly using the pit in the equipment room and feeding it directly to the water point after simple treatment (e.g., filtration). This mode has certain defect because the back flush needs to be carried out in the direct drinking water production process, and some chemical agents can also be used simultaneously, and this waste water also needs to be discharged to outdoor sewage pipe network after collecting through the sump, just can not guarantee the quality of reuse water.
The pipeline direct drinking water system needs to circulate regularly, so that the problem that the water quality is poor due to overlong stay time of direct drinking water in a pipe network is avoided. The water consumption is large in the working days, so that the water quality can be updated regularly. However, at night, on non-working days or in long vacation, the water consumption is small, and the water in the pipe network cannot be updated in time. Although the pipeline direct drinking water system is provided with a timing circulation system, most backwater directly returns to the water purifying tank and returns to the water supply network after ultraviolet disinfection, as ultraviolet disinfection cannot continuously act on water, the circulation period of water in the network is generally longer, the water quality in the system can be reduced after long-time operation, and the safety of drinking water cannot be ensured. Therefore, when the direct drinking water in the pipeline is not used for a long time, the pipeline is also recommended to be emptied periodically, so that the water quality is prevented from being deteriorated, and the treatment cost is also prevented from being increased.
