Description
Technical Field
This patent relates to the collection system of gathering the water sample.
Background
Water sample collection is the basis of water quality detection and an important link of water quality analysis. In order to obtain accurate and comprehensive water quality analysis data, firstly, a correct sampling method and a water sample storage method must be used, and sample sending, analysis and inspection are carried out in time, standardized water sample collection is the premise of obtaining reliable data, the water sample for inspection must have enough representativeness, components do not change, if a sampling link is not made, the operation is strictly careful, and the result is meaningless. Therefore, in order to obtain a water sample with real representativeness, the proper sampling position and reasonable sampling time must be selected and strictly performed according to the standard.
The collection mode of the detection water is different according to the source of the water.
1. Collection of Source Water
① when the surface water is taken from river or lake, it can be directly sucked by a suitable container such as a bucket, and when the sample is taken from the bridge or the like, the bucket tied with a rope or a sampling bottle with a weight can be put into the water to suck water, but it should be noted that the surface water can not be mixed with the substances floating on the water.
② when water of a certain depth is collected in a lake, reservoir, etc., a vertical water sampler is used, this type of device is used in which water flows through the sampler during the sinking process, when the predetermined depth is reached, the container can be closed automatically to take the water sample.
③ spring water and well water can be used for sampling spring water from flowing, when collecting spring water from non-flowing, the water in the pumping pipe should be pumped out, and sampling is carried out after the new water is replaced.
The water sample is collected from the well water and should be pumped sufficiently to ensure the representativeness of the water sample.
2. Collection of leaving Water
The factory water refers to water finished in the water treatment process of a centralized water supply unit. The sampling point of the factory water is arranged before the factory water enters the conveying pipeline.
3. Collection of peripheral water
The end water refers to water delivered to a terminal (a user faucet) from factory water through a water delivery pipe network. Collecting peripheral water, wherein the sampling time is required to be noticed, attachments which can be deposited on a pipeline can be separated out at night, and a faucet is required to be opened to drain water for a plurality of minutes to discharge deposits during sampling. The tap should be disinfected before collecting the sample for microbiological indicator test.
4. Collection of secondary water supply
The secondary water supply is a water supply mode that centralized water supply is stored again, pressurized and disinfected or deeply treated before entering a home and is delivered to a user through a pipeline or a container. The collection of secondary water supply comprises water inlet, water outlet and peripheral water of a water tank (or a reservoir).
5. Collection of distributed water supplies
Distributed water supply refers to a water supply mode in which a user takes water directly from a water source without any facility or with only a simple facility. The collection of the distributed water supply is determined according to the actual use condition.
The water sampler used in the current market mainly comprises a water quality manual sampler and a water quality automatic sampler.
The material of the water quality manual sampler must not affect the composition of the water sample and be easy to wash, and the previous sample cannot have any residue.
The automatic water quality sampler is a bucket type sampler suitable for sampling water in proportion to flow rate and is one intelligent multifunctional sucking water sample bottle-separating sampling device. The sampling device can realize various sampling modes (quantitative sampling, timing flow proportion sampling, constant flow quantitative sampling and remote control sampling) and various bottling modes (single sampling, multiple sampling and mixed sampling of each bottle) according to the sampling requirement of a water sample, and is an ideal sampling tool for realizing scientific monitoring on rivers, lakes, enterprise discharged water and the like. The sampling method (flow proportion and constant flow ration) related to the sewage discharge amount in the sampling can be configured with various flowmeters.
The pipeline type sampler is a sampling device suitable for sampling on a pressure pipeline, and is matched with the whole water quality sampling equipment to finish sampling on the pressure pipeline.
The water quality manual sampler is suitable for field operation and is convenient to carry. However, the manual control may have a deviation of the sampling standard, and some places (such as a river beach with more sludge, a well with a lower water surface, and the like) which are inconvenient for sampling by sampling personnel are inconvenient to operate and cannot sample according to requirements.
The automatic water quality sampler is suitable for indoor operation, can be used together with an online monitor, and can automatically store water samples which are detected to be out of standard by an out-of-standard sample retention function so as to further analyze whether the water samples are out of standard; the conveying of the mixed sample can make the measured value more representative and reduce the defects caused by point representation of the measured value; the remote control sampling can realize random sampling control at any time. However, the automatic sampler needs an operator to clean the sampling bottle and the water sample pipeline after collecting a water sample each time, so that the workload is increased; moreover, the instrument is large and inconvenient to carry, and is not beneficial to field operation.
