Said method includes the following steps: using water pump to pump out the high-turbidity water from water source, pressurizing and feeding the high-turbidity water into the sediment separator to separate and discharge the bulky grain and medium-grained sediment, then passing through the ultrafiltration membrane filter, specific alloy filter, active carbon filter and absolute filter and filtered to obtain the high-quality purified drinking water. Said invention purification equipment comprises machine frame, water pump, sediment separator, ultrafiltration memebrane filter, specific alloy filter, active carbon filter and absolute filter.
Description
What the present invention relates to is the treating plant of a kind of ultra's processing and purifying method and processing and purification employing.Be specially adapted to water-supply plant (waterworks) and produce tap water in this way, draining factory carries out sewage disposal.
The waterworks produces the tap water typical process and will pass through flocculation for entering water factory in the water suction with river band turbidity such as the Changjiang river or the Yellow River at present, precipitation, filter, annotate the chlorine supervisor, this Technology has following weak point: 1, production cycle is long, flocculation, precipitation needs the regular hour, 2, be subjected to weather effect big, the clear water that sinks in the settling tank when raining heavily can become muddy, 3, floor space is big, flocculation, precipitation, filtering all needs certain floor space, 4, daily consumption is arranged: for example spray flocculation agent and chlorine, 5, to the heavy metal contamination in the rivers water, Organic pollutants are handled as yet.
The objective of the invention is to exist weak point that a kind of method for purifying high-turbidity water and equipment thereof are provided at present tap water production technique, ultra through ultra's purifying method and purifying processing device processing thereof can reduce to low-down level with ultra's turbidity, and again indexs such as heavy metal, organic compound and color, peculiar smell, chemical oxygen demand cod and bacterial count in the water are reduced to greatest extent, but still trace elements such as part calcium, magnesium, potassium, sodium have been kept, in water, water quality is improved comprehensively.
Method for purifying high-turbidity water and equipment thereof take following scheme to realize: method for purifying high-turbidity water is:
1, from water source sucking-off and supercharging, input silt particle separator makes the ultra have certain pressure to the employing water pump with the ultra, and pressure range is 2～6kg/cm
2
2, the silt particle separator separates eliminating with the big or middle particle silt particle among the ultra.Ultra with certain pressure enters along the tangent line flow deflector tangential direction on the top of silt particle separator at a high speed, silt particle is under action of centrifugal force among the ultra, be thrown on the silt particle shell separator inwall, along moving under the spiral race alignment, so because great bottom that in the process under the screw, is deposited in gradually of the ratio of silt particle, silt particle separator wash water valve is often opened during the equipment operation, silt particle is discharged from the bottom, current are then because the fluid continuity principle, rise near the spiral medullary ray of silt particle separator, flow out from silt particle separator center water pipe.Roughly all can remove more than big-and-middle-sized silt particle particle 20 μ in the branch of silt particle separator is dried up.
3, will filter by the ultrafiltration membrance filter device through the turbidity water that the silt particle separator was handled, turbidity water flows through ultra-filtration membrane all to be removed all suspended substances and bacterium in the water, and the turbidity in the water can be reduced to below 1 degree at this moment.
4, clean water treatment:
(1) carries out filtration treatment through ultrafiltration membrance filter device treated water through the special alloy strainer with above-mentioned, because device has special alloy in the special alloy strainer, can remove harmful heavy metal in the water, for example lead, mercury, arsenic, cadmium etc., effectively killing bacteria and algae make water quality obtain part and soften.
(2) water of crossing through the special alloy filter process further filters through 1～2 level active carbon strainer again, obnoxious flavoures such as the chlorine in the removal water, hydrogen sulfide, organic compound in the water, and color, peculiar smell, removed by activated carbon cartridge, the chemical oxygen demand cod index is reduced to greatest extent.
(3) will through charcoal filter cross filterable water by all killed bacteriums in the absolute filter filtered water by filtering, promptly make the fine purifying drinking water.Absolute filter can adopt 0.2 μ absolute filter.
Purifying high-turbidity water equipment is made of frame, water pump, silt particle separator, ultrafiltration membrance filter device, special alloy strainer, charcoal filter, absolute filter.Water pump links to each other with the silt particle separator by pipeline, water pump links to each other with Yuan Shui (ultra) by pipeline, with ultra's sucking-off supercharging, send into the silt particle separator, the silt particle separator has housing, former water water inlet pipe is arranged at housing top, and housing top is provided with the tangent line flow deflector near water pipe water-in inwall, lower unit has supporting plate in the housing, supporting plate has the garden arc surface, and the housing internal upper part is provided with rising pipe, and housing bottom is equipped with wash water valve.Ultrafiltration membrance filter device water inlet pipe and silt particle separator rising pipe join, and ultrafiltration membrance filter device rising pipe is connected with the special alloy strainer, and device has ultra-filtration membrane in the ultrafiltration membrance filter device, and sewage valve is arranged at ultrafiltration membrance filter device bottom.Device has the special alloy particle to make filter core in the special alloy strainer, special alloy strainer downstream component has charcoal filter, device has the active carbon filtration core in the charcoal filter, charcoal filter can be provided with 1～2 grade, charcoal filter outlet links to each other with absolute filter by pipeline, and ultra-fine filter core is arranged is that its aperture of the ultra-fine filter core of 0.2 μ is 0.2 μ to device in the absolute filter.The absolute filter outlet links to each other with the pure water inlet control valve.
Method for purifying high-turbidity water and equipment thereof can be processed into the ultra and purify waste water, and are to adopt a kind of brand-new method and apparatus to come treating water.The present invention is applicable to water-supply plant (waterworks) production tap water, be applicable to that also draining factory carries out sewage disposal, for example oily water separation, the separation of iron filings, scum, the separation of silt particle, the recycling or the like of sanitary wastewater (kitchen water, washing water, laundry water etc.).Ultra's turbidity through the inventive method and device processes thereof can ease down to below 1 degree, can remove harmful heavy metal for example lead, mercury, arsenic, cadmium etc. in the water, organic compound is washing composition, organic pesticide, benzene, phenol, trichloromethane etc. and color, peculiar smell for example, obnoxious flavoures such as the chlorine in the removal water, hydrogen sulfide, can kill effectively and remove bacterium and algae in the water, the chemical oxygen demand cod index is reduced to greatest extent, but still kept trace elements such as part calcium, magnesium, potassium, sodium, the quality of water is improved comprehensively.The method for purifying high-turbidity water technological process is simple, easy to operate, good reliability, the treating plant project organization is reasonable, can be assemblied on the same frame, volume is little, in light weight, floor space is little, Installation and Debugging are easy to operate, it is fast to handle ultra's time, can move continuously, excellent popularization use value is arranged.
