The utility model discloses an automatic surface water monitoring system, which comprises a sampling module for sampling a water body and conveying the sampled water body, and is characterized by comprising a precipitation module and a first measurement module which are connected with the sampling module, and a conveying module arranged on the precipitation module, and the second measuring module is connected with the precipitation module through a conveying module. The sedimentation time of the sampling water body in the second sedimentation tank is prolonged according to the turbidity of the water body, the turbidity of the sampling water body is further reduced, the influence on the total phosphorus measuring unit in the second measuring module is reduced, and the data accuracy of the total phosphorus measuring unit is improved.

This utility model discloses a thickener foam elimination structure, comprising: a thickener treatment tank, a rake frame arranged within the thickener treatment tank, and multiple sets of scraper components vertically supported on the rake frame. The multiple sets of scraper components are arranged sequentially and at intervals along the circumference of the treatment tank, moving in response to the fluctuations in the slurry surface within the thickener treatment tank, thereby scraping the mineralized foam in the thickener treatment tank towards the center and causing it to accumulate. A thickener bridge is also erected above the thickener treatment tank, and a spray system is mounted on the thickener bridge. The spray system is used to spray the supernatant from the upper layer of the thickener treatment tank or externally supplied washing water onto the mineralized foam, driving the mineralized foam towards the center of the thickener treatment tank and simultaneously defoaming the foam. This novel structure effectively reduces processing costs, prevents mineralized foam from overflowing outwards through overflow outlets located on the outer periphery of the thickener treatment tank, and significantly reduces the amount of defoamed mineral particles carried away by the overflow.

The utility model belongs to water treatment technical field, specifically discloses a perforated folded plate for sedimentation tank and the sedimentation tank of oblique installation perforated folded plate. The perforated folded plate is the plate -like structure of undulating extension and includes at least three folded plate tops of undulating top end and three folded plate bottoms of undulating bottom end, and the folded plate top of perforated folded plate is adjacent to the folded plate bottom and is provided with a plurality of folded plate holes on or close to the folded plate top. The water inlet and the water outlet of the sedimentation tank are separately arranged in the lower part and the upper part of the pool body, a folded plate support is fixed above the water inlet in the pool body, a plurality of aforementioned perforated folded plates are obliquely arranged on the folded plate support in the pool body, the folded plate top of the perforated folded plate faces upwards and the folded plate bottom faces downwards. The perforated folded plate top of the utility model is provided with the folded plate hole, and the sewage can flow upwards through the folded plate hole, which not only can increase the sedimentation area, but also can realize automatic sludge discharge, has the characteristics of simple structure, wide application range, high sedimentation efficiency and automatic sludge discharge.

The application discloses a kind of copper smelting slag wastewater treatment with sedimentation device, comprising: from left to right sequentially arranged filter part, buffer part and sedimentation part;Rotatable filter cylinder is equipped in the filter part, extraction pump is arranged in the filter part and located in the inside of filter cylinder, and the filter cylinder is used to filter the sewage of inlet pipe entrance.This application, the wastewater in the inside of inlet pipe can continuously fall into the filter cavity located in the top of filter cylinder, then be filtered by the filter screen of cylinder, carry out primary screening, screen the large particles of metal and floating impurities in wastewater, then fall into slag discharge mechanism along with the rotation of filter cylinder, for collection and subsequent processing, and the equipment can obtain the stratification of supernatant and precipitate according to the feedback of turbidity analyzer, and adjust the height of drain pipe, so that it is located in the middle of the stratification of supernatant and precipitate, avoid disturbing supernatant that has been precipitated in the process of drainage, and prolong the precipitation time.
