(4) waste water after step (3) is handled carries out filtration, purification, is separated into water purification and sewage is discharged respectively;
(5) water purification after step (4) processing is imported the water of productive use system, and sewage imports step (1) circularly purifying.
As improvement of the technical scheme, also comprise the following steps:
Water purification after according to its acid-basicity step (5) being handled is thrown in an amount of neutralizing agent.
As improvement of the technical scheme, press the acid-basicity of trade effluent and distinguish, adopt independently production line to handle respectively by above-mentioned steps.
Wherein, the acid-basicity water purification that obtains after process step (5) is handled is neutralizing agent each other.
Another object of the present invention is to provide a kind of equipment that has adopted the trade effluent recycling of aforesaid method, and technical scheme is as follows:
The equipment of trade effluent recycling comprises: press aqueous process streams to the preparation bucket 1, electrolyzer 2, settling centrifuge 3, filtration unit 4, the water purification jar 5 that connect.

As improvement of the technical scheme, filtration unit 4 comprises quartz sand filtration machine 41, activated carbon filtration machine 42 and the RO handler 43 of cascade, according to demand the grade high-accuracy water purifier 44 of cascade again; RO handler 43 has water purification row mouthful and sewage row mouthful, is connected to water purification jar 5 and preparation barrel 1 respectively.
As improvement of the technical scheme, comprise that acid supports water and alkali and support independently production line of two in water, the water purification jar of two production lines communicates with the pipeline intersection of the controlled flow direction.
As improvement of the technical scheme, preparation bucket 1 can be made as a plurality of of cascade with water-purifying tank 5 by different reserves requirements.
Description of drawings
Fig. 1 is embodiments of the invention one.
Fig. 2 is embodiments of the invention two.
Embodiment
The present invention is described further below in conjunction with specification drawings and specific embodiments, but the scope that the present invention protected is not limited thereto.
The method of trade effluent recycling comprises the steps:
(1) trade effluent is concentrated saving;
(2) with the wastewater electrolytic after step (1) processing, isolate heavy metal, greasy pollution substance;
(3) waste water after step (2) processing is carried out centrifugal settling, isolate mud;
(4) waste water after step (3) is handled carries out filtration, purification, is separated into water purification and sewage is discharged respectively;
(5) water purification after step (4) processing is imported the water of productive use system, and sewage imports step (1) circularly purifying.
As improvement of the technical scheme, also comprise the following steps:
Water purification after according to its acid-basicity step (5) being handled is thrown in an amount of neutralizing agent.
As improvement of the technical scheme, press the acid-basicity of trade effluent and distinguish, adopt independently production line to handle respectively by above-mentioned steps.
Wherein, the acid-basicity water purification that obtains after process step (5) is handled is neutralizing agent each other.
Therefore the present invention can have two kinds of embodiments at least, respectively as depicted in figs. 1 and 2.
Shown in Figure 1, be embodiments of the invention one.The equipment of trade effluent recycling comprises: press aqueous process streams to the preparation bucket 1, electrolyzer 2, settling centrifuge 3, filtration unit 4, the water purification jar 5 that connect.Settling centrifuge 3 also is provided with sewage draining exit, and is provided with the mud storage pool 6 that is connected with sewage draining exit.4 of settling centrifuge 3 and filtration units are provided with topping-up pump 7.Filtration unit 4 comprises quartz sand filtration machine 41, activated carbon filtration machine 42 and the RO handler 43 of cascade, according to demand the grade high-accuracy water purifier 44 of cascade again.The RO handler has water purification row mouthful and sewage row mouthful, is connected to water purification jar 5 and preparation barrel 1 respectively.And preparation bucket 1 can be made as a plurality of of cascade with water-purifying tank 5 by different reserves requirements.Throw in an amount of neutralizing agent according to the water purification acid-basicity after handling to the water purification jar, just water purification can be added in the industrial water system again.
