Abstract

The invention relates to a hexavalent chromium- and ammonia nitrogen element-containing vanadium and titanium production wastewater treatment device, and provides a vanadium and titanium industrial wastewater treatment device, which can make hexavalent chromium, ammonia nitrogen, chemical oxygen demand (CODcr), pH, suspended matters, chroma, and biochemical oxygen demand (BOD) generated in the vanadium and titanium production wastewater meet standards and discharged. The device is provided with a grate, an adjusting tank, a first dosing box, a second dosing box, a third dosing box, a sedimentation tank, a vertical flow sedimentation tank, a first inclined tube sedimentation tank, a second inclined tube sedimentation tank, a first water pump, a second water pump, a third water pump, a fourth water pump, a fifth water pump, a sixth water pump, a recoil pump, a slurry pump, an intermediate water tank, an aeration tower, an air blower, a dosing water tank, a double filtration tower, a filter press, a screw pump, a sludge concentration tank, a sludge pump and the like. The wastewater containing overproof hexavalent chromium, ammonia nitrogen elements, CODcr, pH, suspended matters, chroma, and BOD in the vanadium and titanium production process is subjected to homogeneous adjustment, acid-alkali neutralization, solution sedimentation, biochemical reaction, aeration for ammonia removal, double filtration, sludge concentration, pressure filtration for dehydration and the like; and the treated sludge is transported outwards, and the treated wastewater meets standard to be discharged or recycled.

Description

technical field [0001] The invention relates to a treatment of industrial waste water or sewage, in particular to a waste water treatment device for vanadium-titanium production containing hexavalent chromium and ammonia nitrogen elements. Background technique [0002] Wastewater generated during the production of vanadium and titanium, hexavalent chromium, ammonia nitrogen, CODcr, PH, suspended solids, chroma and BOD must be treated, and the treated effluent must meet the national comprehensive wastewater discharge standard. , pH, suspended solids, chroma and BOD, in addition to being treated to meet the discharge standards in the implementation of the overall process, the hexavalent chromium and ammonia nitrogen content in the vanadium and titanium industrial wastewater must also meet the relevant national discharge standards. Contents of the invention [0003] The purpose of the present invention is to provide a method for producing vanadium and titanium, aiming at the ...
