Description

One kind plating garden technique of zero discharge
Technical field
The invention belongs to electroplate garden technical field of waste water processing, and in particular to one kind plating garden technique of zero discharge.
Background technology
Electroplating enterprise typically produces two kinds of waste water, and a kind of is the plating piece rinse water of low concentration, and water is big, pollution factor concentration It is low;Another is to scrap tank liquor and recovered liquid, and the concentration of pollution factor is higher, and water is few.Or the way of traditional garden is The waste water of high concentration is transferred to third party's processing, the consequence brought is to increase the production cost of electroplating enterprise, simultaneously as turning , there is environmental risk in the secondary pollution that shipper pole comes;Dense waste liquid is diluted in the waste water of low concentration and handled together, this The cost of sample processing is high, causes wastewater treatment difficulty big, and the fluctuation of waste water is big, goes out water unstable.
Therefore, the effect that industrial park waste water is focused on how is effectively played, it is energy-conservation to make garden waste water treatment plant Emission reduction contributes, and seeks reuse resource, decrement discharge technology, the need for current plating industry sustainable development.Garden Waste water, waste liquid are produced, in situ remediation is realized, recycling, in reuse, is uniquely going out for following all garden waste treatments on the spot Road and mode.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of that existing process electroplates garden technique of zero discharge there is provided one kind, for plating Low concentration wastewater, high-concentration waste tank liquor in garden production process are individually handled, and form a complete zero-emission circulation System so that water and pollutant obtain the separation of high degree after processing.
To achieve the above object, the technical scheme that provides of the present invention is:
One kind plating garden technique of zero discharge, the processing method that sub-prime is shunted, high-concentration waste are used for the different waste water of concentration Water is handled after being collected separately by independent processing unit, is converged subsequently into biochemical system with low concentration wastewater, low dense Degree waste water is directly entered wastewater treatment center, focuses on rear effluent reuse to production line, pollutant as Resource recovery, terminal Zero-emission is fully achieved, the circulating system in two loops is formed.
Further, the handling process of the high-concentration waste water comprises the following steps:
It is unified to carry out materialized pretreatment after the high-concentration waste water centralized collection that a, enterprise produce, mainly make wherein a large amount of metals dirty Dye thing and organic matter form fixed precipitation, are isolated as solid waste outward transport;
B then by by pretreatment waste water be passed through vapo(u)rization system be evaporated processing make waste water more thoroughly be separated into water and Crystal salt, crystal salt outward transport;
C, evaporation water converge into biochemical system and low concentration wastewater, by the biochemical of depth, membrane filtration processing, are back to production Workshop.
Further, the handling process of the low concentration wastewater comprises the following steps:
A, the low concentration wastewater of centralized collection carry out most of metal pollutant in materialized pretreatment, water and pass through flocculation sediment first Solid waste is formed, is transported outward after separating;
B, pretreated waste water are handled into biochemical system, degradation of organic substances, to the further purification of water quality;
Waste water after c, biochemical treatment is passed through film concentration systems, and waste water is concentrated by combining film device, and the recycle-water of generation is direct Be back to workshop, waste water is further evaporated processing into vapo(u)rization system, make waste water more thoroughly be divided into water and crystallization Salt, crystal salt outward transport;
D, evaporation water by the biochemical of depth, membrane filtration processing, are back to workshop again.
Compared with prior art, the invention has the advantages that:
1st, the waste water of garden high-concentration and low-concentration uses the processing mode that sub-prime is shunted, and forms the discharge cycle system in two loops, has Beneficial to the stable operation of processing system, it is ensured that effluent quality is up to standard;
2nd, waste water, the waste liquid that present invention process can produce garden realize generation, in situ remediation and recycling on the spot, it is to avoid useless The secondary pollution that liquid transition zone comes, reduces the risk of environmental pollution;
3rd, present invention process can realize recycling for water resource, it is ensured that systematic water balance and the supplement for reducing running water, together When produce solid waste outward transport, reach the purpose of zero-emission, make waste water, heavy metal etc. pollute environment risk be reduced to minimum, energy Enough at utmost environmental protections, realize and thoroughly administer, with good dissemination.
Brief description of the drawings
Fig. 1 is process chart of the invention.
Description of reference numerals:Electroplating enterprise 1, high-concentration waste water 2, solid waste 3, materializing strategy 4, vapo(u)rization system 5, crystal salt 6, Normal concentration waste water 7, materializing strategy 8, biochemical system 9, film concentration systems 10, vapo(u)rization system 11, crystal salt 12, solid waste 13 is returned With water 14.
Embodiment
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
One kind plating garden technique of zero discharge, the processing method that sub-prime is shunted is used for the different waste water of concentration, highly concentrated Degree waste water 2 is handled after being collected separately by independent processing unit, subsequently into biochemical system 9 and normal concentration waste water 7 Converge, normal concentration waste water 7 is directly entered wastewater treatment center, focus on rear effluent reuse to production line, pollutant conduct Resource recovery, terminal fully achieve zero-emission, form the circulating system in two loops.
Further, the handling process of the high-concentration waste water 2 comprises the following steps:
