Abstract
The utility model discloses a filtering-rate-variable expansion neutralizing device in wastewater treatment. The device consists of a wastewater collection tank, a lifting pump, a neutralizing reaction device and a filter which are sequentially connected through a pipeline, wherein the neutralizing reaction device is composed of a slagging collection area, a reaction area and a precipitation area from bottom to top; and neutralizing filler is placed in the reaction area. The device disclosed by the utility model has the advantages that filtering-rate-variable expansion neutralizing reaction, filtration and purification can be carried out, and wastewater resource waste and secondary pollution can be avoided, and has the characteristics that filler recycling rate is relatively high and medicine use is reduced, and is suitable for neutralizing inorganic acid industrial wastewater containing hydrochloric acid, nitric acid, sulfuric acid and the like.
Description
Technical field
The utility model relates to a kind of wastewater treatment and becomes filtering velocity expansion neutralising arrangement.
Background technology
Chemical industry, refining of petroleum, pharmacy, plating, metal pickling, Water Treatment workshop etc., can discharge a large amount of acid waste water in process of production, because acid waste water has certain corrodibility, process namely arbitrarily discharging as not adding, can cause very large harm: enter the farmland, can damage soil, cause crop production reduction, and make salting of soil; Enter the river, can affect the growth of waterplant and fish, and worsen water quality; As permeate the ground, perishable structure base, and possibility polluted underground water matter etc.In conventional neutralization reaction technology, generally adopt the dosing reaction, then precipitation process, form a large amount of throw out mud in this process, and these mud also will be processed as Hazardous wastes, not only cause secondary pollution, also useful resource in the waste water of waste.Therefore need to a kind ofly can process pickling waste waters, and reduce the neutralization reaction device of secondary pollution.
The utility model content
The purpose of this utility model is to provide a kind of wastewater treatment to become filtering velocity expansion neutralising arrangement, has the advantages that can carry out simultaneously neutralization reaction, filtration, purification, avoid causing waste water resource waste and secondary pollution.
The purpose of this utility model is achieved through the following technical solutions: a kind of wastewater treatment becomes filtering velocity expansion neutralising arrangement, formed by the wastewater collection pond, lift pump, neutralization reaction device and the strainer that connect with pipeline successively, it is characterized in that: described neutralization reaction device is made of deslagging collecting region, reaction zone and settling region from bottom to top, in being placed with in described reaction zone and filler.
Between described lift pump and water-in, under meter is installed.
The deslagging collecting region side of described neutralization reaction device is provided with water-in and slag-drip opening.
The reaction zone bottom sides of described neutralization reaction device is provided with discharge port.
Further, the top, settling region of described neutralization reaction device is provided with the effluent collection groove.
It is take Wingdale as filler that wastewater treatment becomes filtering velocity expansion neutralising arrangement, the complexes of neutralizing treatment acid waste water.Acid waste water is from wastewater inlet pipe inflow wastewater collection pond, squeeze into the neutralization reaction device by lift pump, when waste water from bottom to up by in the pond during packing layer, because reaction zone diameter becomes large, velocity of flow reduces, filler is in suspended state, mineral acid in waste water namely with filler in calcium, magnesium ion produces chemical reaction, generate the very large calcium of solubleness, magnesium salts and carbonic acid gas, the waste water ph after processing meets emission standard, the filler slag of neutralization is collected from slag-drip opening at the deslagging collecting region and is discharged, and waste residue can reclaim the useful matteies such as heavy metal.When the limestone filler granular filler diameter of selecting is not more than 3mm, the satisfying calcium that covers filling surface that makes of macrobead filler of deslagging collecting region bottom, the magnesium salts compound is stripped from, thereby has guaranteed " active surface " of filling surface, and the filler utilization ratio improves.Waste water after neutralization carries out preliminary sedimentation in the settling region, then collect in the effluent collection groove, from the water outlet inflow filter, discharges from water shoot after further filtering.
The utlity model has following advantage and beneficial effect: a kind of wastewater treatment of the utility model becomes filtering velocity expansion neutralising arrangement, have advantages of to become filtering velocity expansion neutralization reaction, filtration, purification, avoid causing waste water resource waste and secondary pollution to have simultaneously the higher and medicament of filler recycle filter and use the characteristics that reduce.
Description of drawings
Fig. 1 is the utility model structural representation.
Mark and corresponding component title in accompanying drawing: 1-wastewater inlet pipe, 2-wastewater collection pond, 3-lift pump, the 4-under meter, 5-water-in, 6-deslagging collecting region, the 7-reaction zone, 8-settling region, 9-filler, 10-effluent collection groove, the 11-water outlet, 12-discharge port, 13-slag-drip opening, the 14-strainer, the 15-water shoot.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited to this.
Embodiment: as shown in Figure 1, the utility model is comprised of the wastewater collection pond 2, lift pump 3, neutralization reaction device and the strainer 14 that connect with pipeline successively, described neutralization reaction device is made of deslagging collecting region 6, reaction zone 7 and settling region 8 from bottom to top, in being placed with in described reaction zone 7 and filler 9.
Between described lift pump 3 and water-in 5, under meter 4 is installed.
Deslagging collecting region 6 sides of described neutralization reaction device are provided with water-in 5 and slag-drip opening 13.
Reaction zone 7 bottom sides of described neutralization reaction device are provided with discharge port 12.
Further, 8 tops, settling region of described neutralization reaction device are provided with effluent collection groove 10.
In the utility model device when operation: it is take Wingdale as filler 9 that wastewater treatment becomes filtering velocity expansion neutralising arrangement, the complexes of neutralizing treatment acid waste water.Acid waste water flows into wastewater collection pond 2 from wastewater inlet pipe 1, squeeze into the neutralization reaction device by lift pump 3, when waste water during from bottom to up by 9 layers of fillers in the pond, because reaction zone 7 diameters become large, velocity of flow reduces, filler 9 is in suspended state, mineral acid in waste water namely with filler 9 in calcium, magnesium ion produces chemical reaction, generate the very large calcium of solubleness, magnesium salts and carbonic acid gas, the waste water ph after processing meets emission standard, the filler slag of neutralization is collected from slag-drip opening at the deslagging collecting region and is discharged, and waste residue can reclaim the useful matteies such as heavy metal.When the limestone filler 9 granular filler diameters of selecting are not more than 3mm, the satisfying calcium that covers filler 9 surfaces that makes of the macrobead filler of deslagging collecting region 6 bottoms, the magnesium salts compound is stripped from, thereby has guaranteed " active surface " on filler 9 surfaces, and the filler utilization ratio improves.Waste water after neutralization 8 carries out preliminary sedimentation in the settling region, then collects in effluent collection groove 10, from water outlet 11 inflow filters 14, discharges from water shoot 15 after further filtering.The neutralizing treatment of the mineral acid trade effluents such as that this device is applicable to is hydrochloric, nitric acid or sulfuric acid.
As mentioned above, just can realize well the utility model.
