Abstract

A further purifying process for running water includes adding efficient flocculant ST to metering pump of running water, mechanical filter, activated carbon adsorption, 5 microns fine filter, 1 micron fine filter, 0.45 microns fine filter, 0.22 microns fine filter, and directly coming into pipeline of user. Its advantage is effectively removing secondary pollution of running water.

Description

A kind of high-rise building or and the processing method of biotope deep purification for tap water

The present invention relates to a kind of water-treatment technology field, the processing method of particularly a kind of high-rise building or biotope deep purification for tap water.

At present, the tap water of supplying with high-rise building in city or biotope is general to adopt following technology to purify (as shown in Figure 1): former water is through coagulating sedimentation, the while adding of germicide, filter again, enter water reservoir afterwards, after water pump joins high-rise building elevated tank or automatic pump pressurization, be directly inputted in the user pipe.The processing method that such tap water is handled, the one, the water supply of great water requirement and waterworks produces contradiction, thereby makes water quality not good; The 2nd, water factory is usually with the sterilization of chlorination mode, and the chemical property tool activity of chlorine element, the organic substance reaction produces carcinogenic substances such as trichloromethane among the Yi Yushui; The 3rd, when running water pipe network termination contents of residual chlorine was zero, in the course of time, microbial growth became red worm, added that long pipeline gets rusty, the reasons such as infiltration of underground sewage, and had formed the secondary pollution of tap water, often drank, and can influence people's health.At present, though existing various household water filters appear on the market, but all can only be installed in the family room, be 92205048 as the patent No., and name is called " tap water is treatment unit again " and the patent No. is 95223584, name is called " a kind of tap water purifies and purification devices ", its two kinds of patents all are a kind of household water filter devices, and owing to do not adopt the efficient flocculating device, filter core extremely should stop up, the water quality of producing water is relatively poor, can not adapt to the tap water advanced treatment of a building or a biotope.

The purpose of this invention is to provide a kind of is colony with a building or a biotope, adopts volume pump dosing, mechanical filter, activated carbon adsorption, the smart filter of two-stage and the seriation of two-stage micro-filtration the tap water secondary pollution to be carried out the processing method of deep purifying.

The present invention is realized by following technical scheme:

The processing method of a kind of high-rise building or biotope deep purification for tap water, its processing method is: tap water adds the ST efficient flocculant through volume pump, in mechanical filter, filter afterwards, enter again in the activated carbon device and adsorb, and then carry out directly entering user pipe after 5 microns smart filters, 1 micron smart filter, 0.45 micron micro-filtration, 0.22 micron micro-filtration.

The processing method of described a kind of high-rise building or biotope deep purification for tap water, used water pipe is to adopt food grade ABS tubes of material in whole process flow.

The present invention can effectively remove the secondary pollution that comes from tap water such as iron rust, red worm etc. because the technology such as filtration, activated carbon adsorption, smart filter, micro-filtration of using purify tap water, thereby provides the tap water of health more for masses.

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is the process flow sheet of prior art of the present invention;

Fig. 2 is a process flow sheet of the present invention.

As shown in Figure 2, in specific operation process, handling the water yield with 12 tons/hour is example, specific operation process is as follows: (it works as system pressure is 0.24 MPa to the A153-955 volume pump of producing with employing U.S. FILTERME company, the maximum injection rate of volume pump is 4.00 liters/hour), in 50 liters plastic tank, add 150 milliliters of ST flocculation agents (about 150 grams), topped up with water to 50 liter again, adjust metering throw of pump (stroke) speed (speed) percentage value, dosing when the first dosage of ST flocculation agent is from 0.1 mg/litre initial value during each the adjustment makes till pollution index FI15＜4.The liquid medicine that mixes up added in the mechanical filter that steel lining glue or stainless steel are made filter, used filtrate is a double-layer filter material, be hard coal above, be quartz sand below, the height that is seated in the mechanical filter is about 1.2 meters, and water (flow) direction is to go out under enterprising, when the inlet and outlet pressure difference increases to 0.5 Kilogram Force Per Square Centimeter (than original state), recoil, its effect is suspended substance, iron rust and the colloidalmaterial of removing in the water.Filtered water is imported in the activated carbon device again and adsorbed, the filler in the activated carbon device is divided into two-layer, and lower floor is that quartz sand is done background layer, and activated carbon is equipped with on the upper strata, and loading height is about 1 meter, and this process is in order to remove organic substance and the contents of residual chlorine in the water.When activated carbon water outlet contents of residual chlorine＞0.1 milli mg/litre, need to change activated carbon.Import 5 microns smart filters made from steel lining glue or stainless steel, 1 micron smart filter, 0.45 micron micro-filtration, 0.22 micron micro-filtration again through the water after the absorption, effect is to remove 5 microns, 1 micron, 0.45 micron, the granule foreign more than 0.22 micron respectively.After these whole treatment process are finished, can make water quality reach following requirement:

1, pollution index FI15＜4;

2, organic chlorine residue＜0.005 mg/litre;

3, heavy metal (iron, manganese) trace;

4, bacteria containing amount reaches national sweet water standard;

5, pipeline adopts food grade ABS tubes of material, no longer forms new secondary pollution.
