Description
Technical field
This utility model relates to water treatment facilities, is specifically related to a kind of sampling blockage-preventing control system.
Background technology
The device that sample devices blocks that prevents that current sewage treatment plant adopts generally has two kinds, one is prefilter cover, it is arranged on the water inlet of Sewage Plant, play a role in filtering, but the big particle diameter float in sewage can only be filtered by prefilter cover, hence into there is also a lot of suspended particulate substance in sewage in Sewage Plant. When such sampling pump is sampled by sampling tube after starting, the problem that sampling tube, sampling pump block occurs often, thus causing that maintenance and repair is loaded down with trivial details, high in cost of production shortcoming. Another kind is preposition sedimentation filtration case, sewage first passes through preposition sedimentation filtration case and precipitates, enter back in treatment tank, then sample again, although this mode can reduce sampling tube and the frequency of sampling pump blocking, but sewage is sampled after preposition sedimentation filtration case precipitates again so that asynchronous sampling, cause that detection real-time property is poor, without reference value.
