Abstract
The utility model discloses a metal wastewater treatment device, comprising a wastewater tank, a filter and a concentrated water tank which are sequentially connected. A one-level concentration device is connected between the filter and the concentrated water tank, the concentrated water tank is connected with a two-level concentration device and then is connected with the wastewater tank, and a purified water outlet is arranged on the two-level concentration device. Booster pumps and valves are respectively arranged between the wastewater tank and the filter, between the filter and the one-level concentration device as well as between the concentrated water tank and the wastewater tank, and valves are arranged between the one-level concentration device and the concentrated water tank as well as between the two-level concentration device and the wastewater tank. When the metal wastewater treatment device is in operation, wastewater to be pretreated flows out from the wastewater tank and is pressurized by the booster pumps, then the pressurized water enters the filter to be preliminarily filtered under pressure, the filtered water is pressurized by the booster pumps, the pressurized water sequentially enters the one-level concentration device and the concentrated water tank, the effluent water is pressurized by the booster pumps and then the pressurized water enters the two-level concentration device, purified water flows out from the purified water outlet, the wastewater again enters the wastewater tank for secondary treatment, and the circulating treatment is carried out sequentially.
Description
Technical field
The utility model belongs to the wastewater treatment and renovation field, particularly a kind of metallic wastewater treatment unit of electroplating industry.
Background technology
Electroplating industry is one of the current whole world three big contaminated industries.According to statistics, the annual electroplating wastewater of discharging of national electroplating industry has 40 billion cubic meters approximately, is equivalent to the tap water supply amount of several big and medium-sized cities, the shortage of serious exacerbate water resource.Big, the electroplating rinse water severe contamination of electroplating water amount has caused the electroplating industry can't sustainable development.The main generating unit of electroplating wastewater is divided into pre-treatment acid-alkali washing waste water and the electroplating work procedure poaching wastewater is formed, the pollutent that the acidic and alkaline waste water group is wanted for the oil that wash, thing, soda acid etc. become rusty, though can discharge or reuse through simple materialization processing, but the materialization processing cost is higher, traditional wastewater treatment equipment occupied ground is bigger, and working efficiency is lower.
The utility model content
The purpose of this utility model is to provide a kind of wastewater treatment equipment of simple in structure, high efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of metallic wastewater treatment unit, comprise the waste water tank that connects successively, strainer and dense water tank, be connected with the one-level concentrating unit between described strainer and the dense water tank, dense water tank connects waste water tank after connecting the secondary concentrating unit, on the secondary concentrating unit pure water inlet is set, between described waste water tank and the strainer, be equipped with topping-up pump and valve between strainer and the one-level concentrating unit and between dense water tank and the waste water tank, be provided with valve between described one-level concentrating unit and the dense water tank and between secondary concentrating unit and the waste water tank.
Wherein, described one-level concentrating unit is the nanofiltration membrane concentrating unit, and described secondary concentrating unit is reverse osmosis concentrated compression apparatus.
The beneficial effects of the utility model are: pretreated waste water carries out supercharging by topping-up pump during work after waste water tank flows out, entering strainer then tentatively filters under pressure, after the topping-up pump supercharging, enter one-level concentrating unit and dense water tank then successively, the water that comes out enters the secondary concentrating unit after the topping-up pump supercharging, pure water is flowed out by pure water inlet, waste water enters waste water tank once more to carry out the second time and handles, circular treatment successively, and structure is quite simple, and waste water treatment efficiency is high simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 1, the utility model discloses a kind of metallic wastewater treatment unit, a kind of metallic wastewater treatment unit, comprise the waste water tank 1 that connects successively, strainer 5 and dense water tank 2, be connected with one-level concentrating unit 4 between described strainer 5 and the dense water tank 2, dense water tank 2 connects secondary concentrating unit 8 backs and connects waste water tank 1, secondary concentrating unit 8 is provided with pure water inlet, between described waste water tank 1 and the strainer 5, be equipped with topping-up pump 3 and valve 9 between strainer 5 and the one-level concentrating unit 4 and between dense water tank 2 and the waste water tank 1, be provided with valve 9 between described one-level concentrating unit 4 and the dense water tank 2 and between secondary concentrating unit 8 and the waste water tank 1, wherein, described one-level concentrating unit 4 is the nanofiltration membrane concentrating unit, described secondary concentrating unit 8 is reverse osmosis concentrated compression apparatus, pretreated waste water carries out supercharging by topping-up pump 3 during work after waste water tank 1 flows out, entering strainer 5 then filters under pressure, the anode sludge in the waste water, big suspended impurity such as foam fragment is by elimination, after topping-up pump 3 superchargings, enter one-level concentrating unit 4 and dense water tank 2 successively, the water that comes out enters secondary concentrating unit 8 after topping-up pump 3 superchargings, pure water is flowed out by pure water inlet, waste water enters waste water tank 1 once more and carries out the processing second time, circular treatment successively.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
