Abstract
The invention discloses a rotary push injection water sampler. A rotary shaft of a motor is connected with an axis of an impeller; injection cylinder bodies are fixedly connected with a housing, and parallel to an axis of the housing; one part of each injection cylinder body is arranged in the housing; the other part of each injection cylinder body is arranged outside the housing; piston push rods are arranged in the injection cylinder bodies and axially slide; annular stop blocks are arranged at the middle ends of the piston push rods; springs are mounted on the piston push rods in a sleeving manner; one end of each compressed spring is connected with each annular stop block; the other end of each compressed spring is connected with a piston of each piston push rod; and one end of each piston push rod is contacted with a sector rotor of the impeller. When the water sampler operates, the motor drives the impeller to rotate, the piston push rods are separated from the sector rotor of the impeller by the action of resilience forces of the compressed springs, the pistons of the piston push rods move to pump water to be detected, and a water pump is not required, so that an influence on the check accuracy of the water quality caused by pollution of engine oil or gasoline of the water pump to a pumped water sample is avoided.
Description
Technical field
The present invention relates to a kind of water sample acquisition device for environmental monitoring, particularly relate to a kind of rotating bolus injection formula water sampler.
Background technology
Water is Source of life, and the mankind be unable to do without water in life and activity in production, and quality and the human health of Drinking Water water quality are closely related.Along with the raising of socio-economic development, scientific progress and living standards of the people, the water quality requirement of people to Drinking Water improves constantly, water quality standard for drinking water also correspondingly development and perfect.Because the habits and customs of formulation and the people of Drinking Water water quality standard, culture, economic condition, scientific technological advance level, the many factors such as water resource and water quality situation thereof are relevant, not only between various countries, and between the different regions of same country, all difference is also existed to the requirement of drinking water quality.Colourity: majority and discernable when the colourity of potable water is as being greater than 15 degree, when being greater than 30 degree, people feels to detest.In standard, the colourity of regulation potable water should not more than 15 degree.
The inspection of water quality comprises the following aspects:
1, turbidity: for the one of water sample optical property expresses language, in order to represent the limpid and muddy degree of water, being one of most important index weighing water quality good degree, is also examination water treatment facilities purification efficiency and the important evidence evaluating water technology state.The reduction of turbidity just means that the content of microorganisms such as organism, bacterium, virus in water body reduces, and this not only can improve sterilization effect, is beneficial to again the growing amount reducing halogenated organic.
2, smelly and taste: the generation mainly organic existence that water is smelly, may be biologically active increase performance or industrial pollution caused by.The change of the normal stink of public water supply may be the signal that raw water quality changes or water treatment is insufficient.
3, chlorine residue: chlorine residue refers to that water is through chlorination, after contact certain hour, remains in the chlorine dose in water.There is the self-pollution that lasting sterilizing ability can prevent water supply line in water, assure feed water water quality.
4, chemical oxygen demand (COD): refer to chemical oxidizing agent oxidation organic pollutants time required oxygen amount.Chemical oxygen consumption (COC) is higher, represents that organic pollutants is more.Organic pollutants is mainly derived from the discharge of sanitary sewage or industrial waste water, animals and plants are rotted decomposes that rear inflow water body produces.
5, total number of bacteria: the bacterium contained in water, derive from air, soil, sewage, rubbish and vegeto-animal corpse, in water, the kind of bacterium is diversified, and it comprises pathogen.China specifies that the standard of potable water is that total number of bacteria in 1ml water is no more than 100.
6, total coli group: the Bacteria Indicators being a fecal pollution, situation about therefrom detecting can to represent in water whether fecal pollution and pollution level thereof.In water purification process, after disinfecting, total coli group index, if reach the requirement of drinking water standard, illustrates that the former bacterium of other pathogen is also killed substantially.Standard is no more than 3/L in the detection.
7, heat-resisting coliform: it more relevantly reacts the degree of food by humans and animals fecal pollution than coliform, is also the indicator bacteria of water body fecal pollution.
8, colon bacillus: E (E.coli) represents bacterium for Escherichia (Escherichia).General how not pathogenic, for often occupying bacterium in people and animal intestinal, can extra intestinal infection be caused under certain condition.Some serological type strain by force pathogenic, causes diarrhoea, is referred to as disease pathogenic escherichia coli.Enteric bacilli is the similar G-bacillus of a group biological character, is lodged in the enteron aisle of humans and animals more.Escherichia (Escherichia) is a wherein class, comprises various bacteria, the most common with Escherichia coli clinically.Escherichia coli (E.coli) is generally called Escherichia coli, is the normal bacterial parasite in all mammal large intestines, can absorb for body by synthetic vitamin B and K on the one hand.The hyper-proliferative of spoilage organisms and pathogen and fungi can be suppressed on the other hand.But when they leave the parasitic site of enteron aisle, when entering into other positions of body, can infection morbidity be caused.Some bacterial type has pathogenic, causes enteron aisle or urinary tract infections illness.In brief, Escherichia coli=Escherichia coli
When carrying out the sampling of water quality, generally can use water sampler, existing water sampler major part adopts water pump to extract water sample, the machine oil of water pump or gasoline can pollute the water sample extracted, and affects the inspection degree of accuracy of water quality.
Summary of the invention
