Fig. 1 is a kind of chromium plating water treatment device structural representation of the present utility model;
1, chrome-plating bath, 11, the chromium plating dashpot, 12, the chrome-plating bath water jet, 2, washing bath, 21, washing bath water jet, 22, the multi-level water spray mouth, 3, the wastewater collection pond, 4, the chromium water separator, 5, water reservoir, 6, loading area, 7, spillway basin, 8, the chromate waste water collecting tank.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
A kind of chromium plating wastewater treatment unit, it comprises chrome-plating bath 1, chrome-plating bath dashpot 11, washing bath 2, loading area 6, chrome-plating bath water jet 12 is arranged on the chrome-plating bath 1, in the washing bath 2 rinser is arranged, chrome-plating bath water jet 12 is connected with DI with the washing bath rinser, and chrome-plating bath dashpot 11 and chrome-plating bath 1 interconnect by circulating line; The chromium plating wastewater treatment unit also comprises wastewater collection pond 3, chromium water separator 4; Washing bath 2 is by pipe connection wastewater collection pond 3, and wastewater collection pond 3 is connected with chromium water separator 4 by pipeline, and chromium water separator 4 is connected with chrome-plating bath dashpot 11 by a pipeline, and chromium water separator 4 is connected with water reservoir 5 by another pipeline.Water reservoir 5 is connected with wastewater collection pond 3 by pipeline.Wastewater collection pond 3 is outer a spillway basin 7, all has pipeline to be connected with chromate waste water collecting tank 8 on loading area 6 and the spillway basin 7.
During concrete the application, chrome-plating bath water jet 12 is connected with DI with the washing bath rinser, there is sufficient water source to wash workpiece with the sprinkler part that guarantees chrome-plating bath 1 and washing bath 2, chrome-plating bath dashpot 11 and chrome-plating bath 1 interconnect by circulating line, can guarantee that the chromium-containing solution in the chrome-plating bath dashpot 11 in time replenishes in chrome-plating bath 1.After workpiece plated, when proposing chrome-plating bath 1, open top layer chrome-plating bath water jet 12 in chrome-plating bath 1, with 20 liters of/hour water yields workpiece is washed first, workpiece promotes and closes this chrome-plating bath water jet 12 when finishing; Then workpiece being put into washing bath 2 cleans, open this groove top layer washing bath water jet 21 putting into the workpiece process, with 20 liters of/hour water yields workpiece is washed in advance, after workpiece is put into groove, close top layer washing bath water jet 21, fetch boiling water multi-level water spray mouth 22 in the washing trough repeatedly washes workpiece with 20 liters of/hour water yields, guarantees that each orientation of workpiece all is flushed to.Flushing finishes the back and promotes workpiece, and open top layer water jet 21 this moment once more, with 20 liters of/hour water yields workpiece finally washed.The waste water of washing bath 2 flushing workpiece enters wastewater collection pond 3 through pipeline.Chromium water separator 4 extracts chromate waste water by pipeline from wastewater collection pond 3, then chromate waste water is carried out vacuum distillation and handle, and the pure water of generation is discharged in the water reservoir 5 by pipeline and stores.Clear water in the water reservoir 5 can also utilize as pre-wash water by pipeline transportation to washing bath 2 by pipe-line transportation in wastewater collection pond 3 more again.When chromium water separator 4 inner distillatory chromate waste waters reach normality, this chromium-containing solution pumped to get back in the chrome-plating bath dashpot 11 by pipeline again utilize.Workpiece transfer after the washing bath flushing is carried out last artificial flushing to loading area 6 backs to workpiece, and is clean to guarantee the poisonous chromate waste water cleaning down on the workpiece.The waste water that overflows on a small quantity in the wastewater collection pond 3 enters into spillway basin 7, and a small amount of waste water of water wasting in the spillway basin 7 and loading area 6 artificial flushings all arrives chromate waste water collecting tank 8 by pipe-line transportation, is pumped to sewage works through water pump again and handles.
