Description
Technical field
The invention belongs to water treatment device technical field, be specifically related to a kind of rain water on roof fast purification device.
Background technology
Along with urbanization process is accelerated, the problems such as the deterioration of the ecological environment, water resources shortage constantly occur, it is developed all over the world rapidly that urban rainwater carries out second stage employ as water resources.China is the country of a water resources critical shortage, and water resource of per capita is only world occupancy volume per person's 1/4th, and skewness, as the area of lack of water, can not just wait for that external source carries out water transfer, and utilizable water resources should put everything to its best use.Rainwater resource recycling at home and abroad conducts a research and has had the history of decades, and many developed countries have accumulated a lot of advanced experience to the management and use of urban rainwater, is worth us to use for reference.Urban rainwater is a kind of resource of preciousness, and wherein rain water on roof is exactly long-term unheeded a kind of water resources, and because rain water on roof is owing to being convenient to collection, water quality is relatively better, has very large exploitation potentiality in the vast lack of water of China city and area.
In recent years, along with scientific and technical development and comprehensive utilization interdisciplinary, collect and utilize the technology of rainwater to emerge in an endless stream both at home and abroad, the technology of rainwater purification method has been reported a lot, as disclosed patent " micro-polluted water resource utilization low cost deep purification treatment method and the device such as rainwater, wash water " (CN 1974443A), although this technology purifies thoroughly, complex structure, operational difficulty; Disclosed patent " for the rainwater treatment device of rain sewage runoff pollution treatment " (CN 201756478U), although this technology construction flexible structure is simple, its purification is not thorough; Disclosed patent " rainwater purification apparatus " (CN2012545ll), is used biochemical treatment in this technology, comparatively consuming time when processing, and treatment effect is unstable.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of fast purification device for rain water on roof is provided.This technology is by rain water on roof being carried out after the physical treatment course of fast filtering, low-pressure membrane filtration and ultrafiltration membrance filter, and rain water on roof after treatment can directly use or enter natural water body.It is simple, practical that this rain water on roof fast purification device has mechanism, the advantage such as be easy to construction, treatment effect is efficient, quick.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of rain water on roof fast purification device, is characterized in that: comprise water reservoir, intermediate pool, clean water basin, rain water on roof import, inlet valve, hard coal fast filtering layer, baffle plate, floating-ball level switch A, accident overflow port, low-pressure membrane filtering system, hugging, sludge pump, high pressure water pump, ultrafiltration membrance filter system, water outlet, water sucking mouth, working shaft, clear water output, floating-ball level switch B, overflow port.Described water reservoir, intermediate pool and clean water basin are connected successively, and hard coal fast filtering layer, baffle plate, floating-ball level switch A, low-pressure membrane filtering system, hugging, sludge pump and accident overflowing water port are set respectively in water reservoir; High pressure water pump, high-pressure membrane filtering system and working shaft room are set respectively in intermediate pool; Clean water basin arrange respectively floating-ball level switch B and overflow port; Face rainwater ingress arranges inlet valve, and hard coal fast filtering layer is arranged in the middle of baffle plate and retaining pool wall; Baffle plate bottom is lower than fast filtering layer bottom, higher than water reservoir bottom; In water reservoir bottom, hugging is set, hugging is beneficial to the concentrated sinking of mud; In hugging, place sludge pump; Low-pressure membrane filtering system is placed in hugging top, and low-pressure membrane filtering system is connected with high-pressure membrane filtering system by pipe connecting, and at pipe connecting, high pressure water pump is set, and high pressure water pump is controlled by floating-ball level switch A; High-pressure membrane filtering system enters clean water basin by water outlet by water; Working shaft is discharged by the clear water output of pipeline the water clean water basin from the water sucking mouth of pipeline by water, clear water output place sets out water valve; Working shaft is by being controlled by floating-ball level switch B.
A kind of rain water on roof fast purification device, is characterized in that, described a kind of rain water on roof fast purification device is arranged on subsurface.
A kind of rain water on roof fast purification device, is characterized in that, described accident overflow port, and in the time running into the rainfall such as heavy rain and make more greatly the too high situation of water reservoir liquid level, the water in water reservoir is discharged by accident overflow port.
A kind of rain water on roof fast purification device, is characterized in that, described high pressure water pump is controlled by floating-ball level switch A, in the time that water reservoir liquid level is lower, closes high pressure water pump, when water reservoir liquid level is higher, opens high pressure water pump.
A kind of rain water on roof fast purification device, is characterized in that, described working shaft is controlled by floating-ball level switch B, in the time that clean water basin water level is lower, closes working shaft, in the time that clean water basin liquid level is lower, stops working shaft.
The present invention makes the successively fast purification method of process hard coal fast filtering layer, low-pressure membrane filtering system and ultrafiltration membrance filter system of rain water on roof.
When this device carries out work, the rain water on roof of collecting enters water reservoir from rainwater import, after filtering by hard coal fast filtering layer, filter by low-pressure membrane filtering system again, then by high pressure water pump, the rain water on roof after low-pressure membrane filtration system filters being driven into ultrafiltration membrance filter system further filters, rain water on roof after ultrafiltration membrance filter system is filtered enters clean water basin, and the water in clean water basin is transported to behind ground rain water on roof after treatment for water spot by working shaft.Wherein, high pressure water pump is controlled by floating-ball level switch A, closes high pressure water pump in the time that water reservoir liquid level is lower, when water reservoir liquid level is higher, opens high pressure water pump; Working shaft is controlled by floating-ball level switch B; In the time that clean water basin water level is lower, close working shaft, in the time that clean water basin liquid level is lower, stop working shaft; The water of discharging in the time that the liquid level in water reservoir and clean water basin is too high can be directly drained in Urban Rainwater Pipe Networks and go by pipeline.
The invention has the beneficial effects as follows, roofing is collected the rainwater obtaining and is processed rear line supplies or entered natural water body by hard coal fast filtering, low-pressure membrane filtration and these three kinds of methods of ultrafiltration membrance filter.It is simple, practical that this rain water on roof fast purification device has mechanism, the feature such as be easy to construction, treatment effect is efficient, quick.
