The utility model is owing to take above technical scheme, and it has the following advantages:
A kind of electroplating wastewater economic benefits and social benefits of the utility model membrane concentration treatment unit; adopt reverse osmosis brackish water film and reverse osmosis seawater membrane element electroplating wastewater to be carried out the concentrating and separating Treatment for Reuse by the permutation and combination of science; handle and recycling electroplating waste water by the new technology of preparing novel method; thoroughly solve the outstanding problem of electroplating industry development bottleneck and environment protection, realize electroplating wastewater " zero " discharging.And energy consumption is low, high efficiency; Rate of recovery height; Contamination resistance is strong; Waste water reclamation rate height, general pure water reclaims greater than 95%.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of a kind of electroplating wastewater economic benefits and social benefits of the utility model membrane concentration treatment unit embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
A kind of electroplating wastewater economic benefits and social benefits of the utility model membrane concentration treatment unit, it comprises: the sea water desaltination treatment unit of at least one group brackish water treating device and at least two groups can increase or reduce brackish water treating device and sea water desaltination treatment unit according to practical situation.
As shown in Figure 1, be the one-piece construction synoptic diagram of a kind of electroplating wastewater economic benefits and social benefits of the utility model membrane concentration treatment unit embodiment, describe with one group brackish water treating device and three groups sea water desaltination treatment unit below:
Described brackish water treating device 1 is provided with a former pond 11, one-level lift pump 12, sand filtration 13, carbon filter 14, smart filter 15, high-pressure pump 16 and brackish water membrane element 17, and wherein each parts connect by pipeline successively.Can also add the secondary brackish water treating device as required, described secondary brackish water treating device is identical with each parts of one-level brackish water treating device 1, and structure is much the same, and head and the tail pass through pipeline connection.
Described one-level sea water desaltination treatment unit 2 is provided with dense water collecting tank 21, three grades of lift pumps 22, sand filtration 23, carbon filter 24,25, three grades of ram pumps 26 of smart filter and seawater membrane elements 27, and wherein each parts connect by pipeline successively.Described secondary seawater treatment apparatus 3, three grades of seawater treatment apparatus 4 are identical with each parts of one-level seawater treatment apparatus 2, and structure is much the same, passes through pipeline connection.
When using a kind of electroplating wastewater economic benefits and social benefits of the utility model membrane concentration treatment unit, electroplating wastewater at first enters one-level brackish water treating device 1 through after the pre-treatment, when waste water was pumped in the brackish water membrane element 17 by high-pressure pump, the filtration of process brackish water film became pure water, and remaining water then becomes dense water.Pure water collection is back to production, the further again concentration of dense water.When dense water enters one-level sea water desaltination treatment unit 3 and pumps in the seawater membrane element by ram pump, become pure water through the filtration of seawater film, remaining water then becomes dense water.Dense water realizes finally that once more by secondary sea water desalting equipment and three grades of sea water desalting equipment concentration dense water concentrates, the process of pure water reuse.
A kind of electroplating wastewater economic benefits and social benefits of the utility model membrane concentration treatment unit, adopt the economic benefits and social benefits membrane concentration to handle and recycling electroplating waste water key is to combine the brackish water treatment technology and the sea water desaltination treatment technology is applied on the electroplating wastewater processing, use efficient pre-treatment to overcome dirty stifled problem, the concentrated solution saltiness progressively increases in the engineering that progressively concentrates electroplating wastewater, core technology is to use brackish water film and sea water desaltination film that the waste water of supersalinity is concentrated, and acts on higher operating pressure and forces waste water salt, water sepn on the reverse osmosis membrane.
The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
