Embodiment 1
[0033] Select a residential area to carry out engineering transformation of its water supply pipeline according to the described technology. The membrane flux of the ultrafiltration membrane is constant at 30L / (m2.h). After 4 months of operation, the membrane flux has no attenuation, and the operation of the ultrafiltration membrane is stable. ; According to irregular normal water production, the positive flush ultrafiltration membrane runs stably; its water quality parameters are shown in Table 1.

The invention discloses an indoor water supply pipeline system based on ultrafiltration and deep purification. The indoor water supply pipeline system comprises a house pipe opening, a house water meter and a water facility, wherein municipal water supply passes through a house pipe opening and reaches the water facility through the house water meter; an ultrafiltration film device is arranged behind the house water meter; filtration is carried out by residual pressure of a pipe network; inlet water of the ultrafiltration film device is municipal running water entering through the house pipe opening and the house water meter; outlet water is divided into water produced by ultrafiltration and water discharged by ultrafiltration jetting; the water produced by ultrafiltration is supplied for drinking, bathing and cooking; the water discharged by ultrafiltration jetting is supplied for flushing the toilet and washing clothes; the ultrafiltration film device comprises an ultrafiltration film component; and the ultrafiltration film component runs in an internal compression dead-end filtration manner. According to the indoor water supply pipeline system, the residual pressure of the pipe network is fully utilized to ensure normal operation of ultrafiltration; the energy consumption is reduced; the utilization rate of water is improved; the quality of water with different purposes is ensured; and the water cost is reduced. The indoor water supply pipeline system does not occupy an existing space, is convenient to operate and has the advantages of low energy consumption and high raw water utilization rate.
Description
technical field [0001] The invention relates to an indoor water supply pipeline system based on ultrafiltration deep purification, and belongs to the technical field of building water supply. Background technique [0002] At present, there are still organic matter and other pollutants in the source water after being treated by the water plant. When the factory water is transmitted through the water distribution system, complex physical, chemical, and biological effects will occur in the pipeline, resulting in deterioration of water quality. At the same time, there are problems caused by pipeline damage Exogenous pollution, long residence time in water storage equipment, exhaustion of remaining disinfectants, bacterial growth, increased turbidity, etc. When the pipe network water reaches users, the water quality of residents' faucets may not meet the "Drinking Water Hygienic Standards" (GB5749-2006) and threaten the drinking water health of urban residents. Therefore, in ord...
