The utility model relates to a waste water recycling and treating device technical field is a manual recovery processing device of steam -water system of thermal power plant low temperature sample frame drainage, and it includes low temperature sample frame, collector pipe, water tank, outfall sewer and ion exchange column at least, and the export of the drain pipe of taking a sample and the export of instrument drain pipe all are linked together with the import of collector pipe. The internal and external network physical isolation data exchange device is reasonable and compact in structure,the volume of equipment is little, small occupation area, the construction cost is few, the transformation degree of difficulty is little, in can setting up between thermal power plant's soda sample,and convenient for operation, be applicable to production site, the water sample is through the simple back of handling, recycle in can mending steam -water system, recovery processing through to thedrainage of sample frame is recycled, can reduce the moisturizing rate of unit, realize rationally recycling of water, water in the water tank for providing the ultrapure water, laboratory between thesoda sample satisfies daily use after also can select ultra -pure water system to handle simultaneously, make like this the utility model discloses the usage is more extensive.
