Description
Technical field
The utility model relates to the water reuse apparatus technical field, refers in particular to water reuse apparatus in a kind of PCB industry.
Background technology
The PCB enterprise production will produce a large amount of rinse water, contain a large amount of pollution factors such as heavy metal ion in these rinse water.Past utilizes the method for chemical precipitation that heavy metal ion is deviate from directly discharging of back usually, causes wastewater discharge very big.
As everyone knows, water resources is deficient day by day in the world, so State Environmental Protection Administration proposed the call of energy-saving and emission-reduction, require each manufacturing enterprise carry out in water reuse work, the conserve water resource is cut down wastewater emission amount simultaneously.
The usual method of water reuse was during the PCB industry was carried out at present, after suitable rinse water collection is gathered, at first carried out precipitation process, and then utilized reverse osmosis system to carry out middle water reuse work.The common disadvantage that this method exists is: 1. organism is deviate from not thoroughly in preprocessing process, causes the dirt of RO film stifled easily.2. the dense water pollutant of reverse osmosis system usually surpasses emission standard, need repeat precipitation process, causes cost of investment to increase.
Therefore, based on the defective of above-mentioned existing P CB industry technology of middle water recycle, need improve existing P CB industry technology of middle water recycle.
The utility model content
The purpose of the utility model is that the deficiency to prior art provides water reuse apparatus in a kind of PCB industry, and it is existing that water reuse apparatus has solved existing P CB industry technology of middle water recycle in this PCB industry: organism deviates from preprocessing process that the dirt that does not thoroughly cause the RO film easily is stifled, dense water pollutant exceeds standard, needs defectives such as repetition precipitation process, cost of investment height.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
Water reuse apparatus in the PCB industry includes comprehensive pond, is connected with pH regulator system, quartzite strainer, activated charcoal filter, security personnel's strainer, reverse osmosis system on the outlet conduit in comprehensive pond.
Be connected with the pH regulator system on the said reverse osmosis system outlet conduit.
The inlet channel in said comprehensive pond comprises oil removing rinse water pipeline, nog plate rinse water pipeline, heavy metal rinse water pipeline.
Be connected with pH regulator system, activated charcoal filter, adsorption filter on the said oil removing rinse water pipeline.
Be connected with pH regulator system, disc filter on the said nog plate rinse water pipeline.
The beneficial effect of the utility model is: the absorption exchange of carrying out pH regulator and each strainer through the pH regulator system is filtered; Pass through reverse osmosis system again; Can omit the settling system in the preprocessing process; The intermediate water reuse system equipment cost is reduced, and floor space reduces, and makes rinse water can reach emission standard.
Description of drawings
Fig. 1 is that the structure of the utility model connects synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1, water reuse apparatus comprises in the utility model PCB industry: comprehensive pond is connected with pH regulator system, quartzite strainer, activated charcoal filter, security personnel's strainer, reverse osmosis system on the outlet conduit in comprehensive pond.
Select the water source of the main rinse water of circuit board industry, mainly comprise three kinds of oil removing rinse water, nog plate rinse water and heavy metal rinse water as the reuse water system.Directly enter Waste Water Treatment for the very strong de-smear rinse water of organic content very high demoulding development rinse water, oxidisability etc., to ensure the steady running of reverse osmosis system.
Principal pollutant in the nog plate rinse water are suspended substance and a spot of heavy metal ion, can filter through disc filter and remove most suspended substances, and the template water after the filtration directly is pooled to comprehensive pond, merge with other rinse water and carry out the deep purifying processing.
Contain a certain amount of heavy metal ion and a spot of organic additive in the oil removing rinse water,, usually cause the dirt of RO film in the subsequent processes stifled though organic additive content is not very high.Thoroughly deviating from organic additive is a key factor that ensures reverse osmosis system steady running, and conventional activated charcoal filter can be deviate from a part of organism, but removal effect is not thorough.Among the present invention through using a kind of polymeric adsorbent thoroughly to solve this problem.
Polymeric adsorbent is a kind of porous resin that new development is got up in field of polymer technology recent years, is a kind of organic polymer interpolymer with macroporous structure.Polymeric adsorbent can be divided into polarity, low-pole and nonpolar three types according to the character of its functional group.Can be subdivided into a lot of model kinds according to the microscopic aperture difference of controlling in synthetic monomer component difference and the building-up process.
The characteristics of polymeric adsorbent are different according to skeleton difference that constitutes resin and aperture; The different material of available selectable absorption; Selected a kind of special polymeric adsorbent among the present invention for use; Widely used tensio-active agent had very strong adsorptive power during this resin cleaned the oil removing of PCB industry, can thoroughly remove the organic additive composition in the oil removing rinse water.
Mix with the heavy metal rinse water of discharging during PCB produces through the nog plate rinse water of above-mentioned processing and oil removing rinse water and to have constituted comprehensive rinse water.More heavy metal ion and micro-suspended substance and the organism of main meaning in the comprehensive rinse water; Can be through the suspended substance and the organism of quartzite strainer and activated charcoal filter filtering trace; Because inorganic salt content is higher in the comprehensive rinse water; Specific conductivity is generally more than the 1000us/cm, and therefore adopting reverse osmosis equipment to carry out desalting treatment is both economical treatment measures.
Form the dirty stifled problem of RO film that the inorganic salt incrustation scale causes in the reverse osmosis system heavy metal ion that will prevent in service, through the slightly acidic method of adjustment water inlet pH, prevented the generation of inorganic salt incrustation scales effectively among the present invention.
In order to reduce influent quality fluctuation influence as far as possible to the reuse water system, recycle pump all is installed in each collecting tank, reach the purpose of even water quality through the stirring action of recycle pump, can reduce the volume of collecting tank like this, saving equipment takes up an area of the space.
The nog plate rinse water can be filtered through disc filter and removed most suspended substances; Filtering accuracy is generally selected 25um in the design; The type selecting of disc filter need be confirmed according to handling the water yield; The backwash mode of disc filter can be as the case may be confirms flexibly, selected from source formula to add the cleaning way of valve among the present invention.
The oil removing rinse water at first need be used micro-strainer filtering and removing suspended substance wherein, can guarantee the activated charcoal filter and the adsorption filter steady running of back like this.The filtration capacity of activated charcoal filter is generally pressed 8m
3/ m
2Design, the filtration capacity of adsorption filter is generally pressed 6m
3/ m
2Design.
