Abstract
The utility model relates to a chemical reaction device for electroplating waste water treatment. The reaction device comprises an adjusting pool, a primary reaction tank, a lifting pump, a secondary reaction groove, a middle tank, a concentrating tank, a stirring machine, baffles, a press filter and a sludge pump, wherein the lifting pump is positioned between the adjusting pool and the primary reaction tank; the stirring machine is positioned above the primary reaction tank and the secondary reaction tank; the baffles are positioned in the primary reaction tank, the secondary reaction tank and the middle tank; and the sludge pump is positioned between the middle tank and the press filter. Through the adoption of the chemical reaction device for the electroplating waste water treatment, flow is blocked by the baffles so that water flow entering the reaction tank rises to a top overflow opening from the bottoms of the baffles, so as to form a flow state which drives the water flow to stir, so that assistance is provided for the stirring machine to more uniformly mix added medicines. The water enters from the upper end of the reaction tank and exits from the lower end of the baffle in the tank; and after the water level rises to the overflow opening, the water is conveyed to the next reaction device from the overflow opening, so that a water inlet inertia effect can be avoided, the water outlet is uniform, no flowing dead angle is generated, hydraulic retention time is prolonged and a short flow phenomenon is prevented.

Chemical reaction equipment is inhomogeneous because stir inhomogeneous medicament and the waste water reaction of causing through regular meeting, though add stirrer in reacting, because of the water yield excessive; Can not mix fully; If strengthen to stir the unstable that shark's fin can increase reactive tank on the contrary, and if edge can not get for a long time flowing, little when big in the time of can causing flooding quantity; Water quality is inhomogeneous, and even short stream takes place.
The utility model content
The purpose of the utility model is to make that the metals ion in the electroplating wastewater fully reacted before getting into micro-filtrate membrane filtration, reaction evenly improves the efficient of chemical reaction.
The technical scheme of the utility model is: a kind of electroplating wastewater processing chemical reaction equipment, and described reaction unit comprises equalizing tank, the first order reaction groove; Lift pump between equalizing tank and first order reaction groove, second order reaction groove, medial launder; Thickener is positioned at first order reaction groove and the stirrer above the second order reaction groove, is positioned at the baffle plate of first order reaction groove, second order reaction groove, medial launder; Pressure filter, the sludge pump between thickener and pressure filter.
Preferably: plane chamfer baffle plate is set respectively in described first order reaction groove, second order reaction groove, the medial launder.
Preferably: described baffle plate is crossing with two rectangular cell walls of above-mentioned first order reaction groove, second order reaction groove, medial launder respectively, and height of baffle plate will be lower than the height of groove, and reserves the mouth of a river in the baffle plate bottom.
Preferably: between described first order reaction groove and the second order reaction groove, between second order reaction groove and the medial launder, medial launder is provided with riser with cell wall between the thickener and is communicated with.
Preferably: described riser is positioned at the vertical projection length range of baffle plate cutting cell wall.
Preferably: be provided with sludge pump between described medial launder and the pressure filter, sludge pump is transported to sedimentary mud in the neutralizing well in the pressure filter and dewaters.
The beneficial effect of the utility model is: the described electroplating wastewater chemical reaction equipment of the utility model, and adopt the baffle plate of unique design to flow out water at a distance from slime flux, advantage is:
1, baffle plate makes the current that get in the reactive tank rise to the top riser from the baffle plate bottom at a distance from stream, and the fluidised form that forms thus drives current and stirs, and it is more even that auxiliary stirrer mixes dosing.
2, from the water inlet of reactive tank upper end; By the lower end water outlet of groove Internal baffle, water level is transported to next reaction unit from riser after rising to riser, can avoid producing the inertia effect of water inlet like this; Make water outlet even; Do not produce flow blind angle, prolong hydraulic detention time, prevent the generation of short flow phenomenon.

Embodiment
The utility model is specifically designed to the chemical reaction stage in the electroplating wastewater film processing system, and is main in order to prevent the generation of the short-and-medium flow phenomenon of chemical reaction reaction process, and current are mixed.Further set forth the utility model in conjunction with accompanying drawing:
A kind of electroplating wastewater processing chemical reaction equipment, described reaction unit comprises equalizing tank 1, first order reaction groove 3; Lift pump 2 between equalizing tank 1 and first order reaction groove 3, second order reaction groove 6, medial launder 7; Thickener 8 is positioned at first order reaction groove 3 and the stirrer 4 above the second order reaction groove 6, is positioned at the baffle plate 5 of first order reaction groove 3, second order reaction groove 6, medial launder 7; Pressure filter 10, the sludge pump 9 between thickener 8 and pressure filter 10.Be set to plane chamfer baffle plate 5 respectively in described first order reaction groove 3, second order reaction groove 6, the medial launder 7.Described baffle plate 5 intersects with two rectangular cell walls of above-mentioned first order reaction groove 3, second order reaction groove 6, medial launder 7 respectively, and baffle plate 5 height will be lower than the height of groove, and reserve the mouth of a river in baffle plate 5 bottoms.Between described first order reaction groove 3 and the second order reaction groove 6, between second order reaction groove 6 and the medial launder 7, medial launder 7 is provided with riser 11 with cell wall between the thickener 8 and is communicated with.Described riser 11 is positioned at the vertical projection length range of baffle plate 5 cutting cell walls.Be provided with sludge pump 9 between described medial launder 7 and the pressure filter 10, sludge pump 9 is transported to dehydration in the pressure filter 10 with sedimentary mud in the neutralizing well.
