Problems solved by technology
[0004] (1) The operation is cumbersome: the filter paper needs to be folded and put into the funnel, then the funnel is placed on the shelf, and the Erlenmeyer flask is connected underneath;
[0005] (2) Water samples are easily polluted: after the filtration is completed, the filtrate needs to be transferred into a polyethylene sample tube for testing on the machine, and the process of filtration and transfer is easy to bring pollution;
[0006] (3) Troublesome cleaning: after filtering a water sample, the funnel and conical flask need to be cleaned separately, which is very troublesome
[0008] The more important point is that traditional filter devices and various current batch filter devices are made of glass, and glass has a strong adsorption capacity for heavy metals. For the detection of heavy metals in water samples, using glassware will increase the pollution of water samples. risks of

The invention relates to a batch filter device and a batch filter method of heavy metal-containing waste water. The filter device comprises an outside frame, a suction cavity is formed in the frame in a surrounding manner; the inner side of the suction cavity is communicated with at least one suction connector; the other end of any of the suction connectors is communicated with the filter device for filtering a water sample; multiple suction holes are formed in the outer side of the suction cavity and any one of the suction holes is plugged by a hole plug; the outside frame is provided with a top cover. According to the batch filter device, multiple to-be-tested water samples can be filtered or sucked into sample tubes at one time; the operation is simple; the clean is convenient and the pollution to heavy metal in water samples can be avoided.
Description
technical field [0001] The invention relates to a filtering device, in particular to a batch filtering device and method for heavy metal-containing wastewater. Background technique [0002] Heavy metal elements such as arsenic and mercury in the desulfurization wastewater of power plants need to be tested regularly. The number of tests is large and the water samples must be filtered before testing. At present, the atomic fluorescence spectrometer used for the determination of these two heavy metals is equipped with an automatic sampler. After a batch of water samples are filtered, they can be moved into a special polyethylene sample tube and then placed on the sampling carousel rack for automatic detection. Therefore, a large number of water samples need to be filtered and transferred before each machine testing. [0003] Traditional filtering methods have the following disadvantages: [0004] (1) The operation is cumbersome: the filter paper needs to be folded and put int...
