Description
Technical field
The invention belongs to the technology category of water quality detection；Particularly relate to the water quality detecting device towards household water purification system and inspection
Survey method.
Background technology
China accounts for the 21% of population in the world, has the earth water resource of 6%, i.e. water resource of per capita and is only world's water per capita
Flat about 1/4th；Water resource posseses congenital defect." China Environmental State Bulletin in 2008 " is pointed out, 658 cities, the whole nation
The 2/3 of city has been in hydropenia or serious water shortage state；Water environment pollution situation is the most pessimistic: the I of China's main river～Group III
Water quality section is 64.2%, bad V class 17.2%；Shortage of water resources, water environment pollution, Ecology are impaired, three's reciprocal effect, that
This superposition, constrains the sustainable development of economy and popular healthy level.Recalling past pains, government is formed with various circles of society up and down
Common recognition: comprehensively administer water pollution, rational utilization of water resources；Continue from the Nature real embarrassing of the immoderate one-way road asked for, treasure the mankind
The water resource depended on for existence, everybody must carry the heart revered." China Environmental State Bulletin in 2015 " authority issue: I～III
Class, IV～V class and bad V class water quality section ratio are respectively 63.1%, 27.7% and 9.2%；Obviously, exert through the unremitting of several years
Power, has reversed the situation that water environment deteriorates increasingly finally, presents the gratifying sign that water quality is become better, the water supply security difficulty that puzzlement is popular
Topic is faded in and is dissolved dawn.In April, 2015, the water harnessing action plan that China is with a highest standard, it is commonly called as " ten, water " and formally issues, control
Reason water pollutes the legal perspective rising to embody will of the state.
Along with progress and the awakening of health idea of water purification technology, middle and high end family no longer stops at water safety with water
The basic demand of low side, seek the Demand-side of high-quality domestic water and expedite the emergence of various personalized water purification demand；Demand promotion supplies,
The water purification industry of high-quality domestic water supply side is arisen at the historic moment, 2015, the whole industry output value 74,000,000,000.Domestic water purifying presses purposes
It is divided into by type water purification and the big class of non-type water purification two.Reverse osmosis unit, non-type is configured with type household water purification system
Household water purification system then vacancy；The former is limited by the limited water treatment capacity that reverse osmosis unit is intrinsic--and water yield need less than normal are set up
Storage tank, by buffering method for application water purification, the latter be inclined to " What You See Is What You Get "--the in real time non-type water purification of offer.Mesh
Before, the reputable brand of domestic market household water purification system has
ECOWATER SYSEMS happy mouth board water purifier ETF2100PF10: non-type water purification 3T/h.A.O.Smith company
AO Smith board water purifier SR400-C3: with type water purification 1.054L/M.
Run quickly safe Pure Water Equipment Co., Ltd to safe board water purifier BNT-S08-Z02F: non-type water purification 2.5T/h.
In Domestic water purifying field, the personalized typical case demand of user's request side is summarized as follows:
1, calcium ions and magnesium ions is filtered.The soft water of low calcium and magnesium ion has skin moistening maintenance function, can remove the dirt in skin cell
Thing, delay skin aging；Soft water also has medicated clothing to be helped and washes function, make that medicated clothing is soft, color and luster as new, the washable number of times of medicated clothing increases
Adding 33%, detergent usage amount reduces 55%；Etc..
2, chlorine residue is removed.Chlorine exciting eye, nose, larynx and upper respiratory tract, make hair dry and astringent, fracture, bifurcated.GB5749-
2006B standard specifies, chlorination (bleaching powder) >=0.3mg/l in tap water；Chlorination sterilization is effective disinfection technology of high performance-price ratio,
But in water, human body is caused no good by the chlorine residue of residual after Sha Jun.

Send out hyperthyroidism；Copper intake exceeds standard and will cause vomiting, diarrhoea, weak, liver cirrhosis, and senile dementia.
At present, the former water sample detecting to as if being derived directly from environmental water systems that main flow water quality detecting device focuses on, or warp
Tap water sample after water factory's process.Water sample detection method successively experienced by chemical method, spectrophotography, electrochemical process, chromatograph
Method, detection foundation is " water quality monitoring specification " SD127-84；Routine five parameter that " water quality monitoring specification " must be surveyed be water temperature, pH,
Dissolved oxygen, electrical conductivity, turbidity, containing parameter has hardness, heavy metal, ammonia nitrogen, nitrate nitrogen, total nitrogen, chloride ion, fluorion, phosphorus
Hydrochlorate, total phosphorus, TOC, HC Hydrocarbon, petroleum-type, permanganate index.Above-mentioned detection method precision is high, concordance is reliable
Property obtain theoretical and experiment support, therefore detection data have legal effectiveness；Shortcoming is that device volume is big, technical threshold is high, behaviour
Make step many, detection the cycle long, be not suitable for Site Detection, family detection.Portable field water quality detecting device selects based on ion
Selecting property electrode technology；Easy to detect fast it is not related to reagent consumptive material, layman also competent detection, therefore deeply blue or green by industry
Look at.The shortcoming of ion-selective electrode water quality detecting device is to measure the special electrode that different ions need to be different, therefore apolegamy
Electrode is wide in variety, calibration standard solution is many；Additionally, the ionic species that electrodes selective measures even to this day is fairly limited；3rd,

TDS value because TDS size to characterize the hydrotrope how many, the hydrotrope is how many and electric conductivity (electrical conductivity) positive correlation of water.TDS is
One comprehensive water quality index, detection technique threshold is low, without reagent, is in industry used widely.It must be noted that
TDS index cannot meet the individual requirement of water purification detection Demand-side, with the continuous lifting of water purification user health concerns degree,
The deficiency of TDS single detection parameter day by day shows especially, urgently improves.On the other hand, it is clean that ripe water purification user not only payes attention to domestic
The initial purchase commodity of water system, more payes attention to the expense of O&M spending, particularly consumptive material.Such as, with type water cleaning systems SR400-
C3 price 5238 yuan, consumptive material RO film price 1200 yuan；Non-type water cleaning systems ETF2100PF10 price 19874 yuan, consumptive material is filtered
