Description

Water quality testing preliminary treatment filter equipment

Technical Field

The utility model relates to the field of water quality detection, in particular to a water quality detection pretreatment filtering device.

Background

Water (chemical formula: H2O) is an inorganic substance composed of two elements of hydrogen and oxygen, and is colorless and odorless transparent liquid at normal temperature and pressure. Water is one of the most common substances on earth, an important resource for all life including human beings, and also the most important component of organisms.

The drinking water mainly considers the influence on human health, and the water quality standard of the drinking water comprises physical indexes, chemical indexes and microorganism indexes; for industrial water, consideration is given to whether the product quality is affected or the containers and pipes are easily damaged.

Before water quality detection, pretreatment is needed, components contained in a water sample are complex, most of pollution components are low in content, and the water sample has different forms, so that before analysis and determination, pretreatment is needed, the components to be determined reach the forms and concentrations required by a determination method, and coexisting interference components are eliminated. The principle of water sample pretreatment is to remove the interferents to the maximum extent, the recovery rate is high, the operation is simple and convenient, the time is saved, the cost is low, and the influence on the human body and the environment is avoided.

When determining inorganic elements in a water sample containing organic substances, digestion treatment is needed, the aim is to destroy organic substances, dissolve suspended solids, oxidize elements to be determined in various valence states into single high valence states or convert the elements into inorganic compounds which are easy to separate, and the digested water sample is clear, transparent and non-settling, and the methods for digesting the water sample comprise a wet digestion method and a dry digestion method (dry ashing method).

When the content of the component to be detected in the water sample is lower than the detection limit of the analysis method, enrichment or concentration must be carried out; when coexisting interfering components exist, separation or masking measures are necessary to enrich and separate the components often inseparably and simultaneously, and the methods include filtration, volatilization, distillation, solvent extraction, ion exchange, adsorption, coprecipitation, chromatography, cryoconcentration and the like, and the methods are selected and used in combination with specific situations.

In the process of pretreatment of a water sample, a filtration operation is one of the commonly used pretreatment methods, or is used as an auxiliary method of other treatment methods, for example, in an adsorption method, one or more components in the water sample are adsorbed on the surface by using a porous solid adsorbent, a filtration operation is required to separate the solid adsorbent from the water sample, and in a coprecipitation method, some insoluble compounds in a solution are carried out and precipitated together in the process of forming a precipitate, and then the precipitate is required to be separated from a liquid water sample by filtration.

In such adsorption method and co-precipitation method, the filtration operation of the water sample is conditionally limited, wherein the most important is the temperature control in the filtration process, because the temperature will have a great influence on the result of water sample treatment in the water sample pretreatment process, the adsorption or co-precipitation treatment of the water sample at different temperatures, the species of the adsorbed or precipitated substances are different, and the adsorption or precipitation effect of the same substance at different temperatures is also greatly different, the current water quality detection pretreatment filtration device can not control the temperature of the water sample filtration process, because the time required for filtering the water samples with different detection requirements is different, if the filtration process is not controlled by a certain temperature, the temperature change of the water sample in the filtration process can be larger, the water sample treatment effect can be affected, and the error of water sample monitoring can be caused, when the water sample in a factory or outdoors is detected, probably contain the grease in the water sample, and follow-up water sample pretreatment process uses inorganic compound to handle the water sample mostly, can not degrade the grease that separates wherein, bring inconvenience for follow-up processing and detection, present water quality testing pretreatment filter equipment is mostly simple structure, can not realize the filtration needs among the water quality testing pretreatment process well, some filter equipment designs complicatedly, inconvenient dismantlement is washd and is overhauld, bring inconvenience for the detection, so, provide a water quality testing pretreatment filter equipment here.
