System.
Background technique
Printed wiring board factory, sewage species are various, and water-quality constituents is complicated, wherein organic sewage (containing waste liquid) clay content it is high,
High organic content, pH value are high, have certain viscosity, in common technology, need individually to carry out acid out and flocculated materialization is located in advance
Reason.
Organic sewage main indicator:
Common organic sewage treatment process:
1, organic sewage flow to catch basin from workshop certainly, then is promoted to the tune that conditioning tank carries out water quality and water by pump
Section；
2, sewage in conditioning tank is pumped into acid precipitation reaction slot, sulfuric acid is added in slot, adjust pH value to 2.5-3, sewage can analyse
It a large amount of hydroxy resin and floats, is separated from sewage by slag-scraper out；
3, acid precipitation reaction slot water outlet enter coagulation tank 1, added in coagulation tank 1 sodium hydroxide, PAC carry out acid-base neutralization and
Flocculation, water outlet enter coagulation tank 2, added in coagulation tank 2 PAM help it is solidifying.Water outlet enters back segment precipitating/air-flotation system and carries out muddy water
Separation, water outlet flow to composite wastewater conditioning tank；
4, mixed composite wastewater sequentially enters copper-stripping reaction slot, first stage precipitation tank, contact break reactive tank, removes reaction of Salmon-Saxl
To go copper ion and complex copper in water removal, final outflow water enters biochemical reaction tank for slot, flocculation reaction slot, second-level settling pond, removes
The pollutants such as COD, ammonia nitrogen, total nitrogen in sewage；
5, in the process caused by sludge drain into sludge concentration tank and be concentrated, it is to be drained off.
It facts have proved that there are following disadvantages with system processing organic sewage:
1, organic sewage PH is alkaline, usual PH > 12, and acid precipitation reaction need to adjust sewage PH value and usually adjust PH to acid
It is subsequent to add alkali tune pH value to be conducive to flocculate to 8-9 again to 2.5-3.Its front and back adjusts pH value repeatedly and consumes a large amount of medicaments；
2, organic sewage pretreatment is independent treatment process unit, need to increase the investment cost of a whole set of processing equipment.Fortune
Between the departure date, since the acid and alkali corrosion in its reaction process is stronger, the later period can also generate certain maintenance cost；
3, acid precipitation reaction slot and coagulation tank 1 are required to preferable PH control.Fluctuation and medicament due to water water quality
Dosage accurately controls problem, and artificial adjust then is difficult to balance, and adjusts frequency height, so needing higher automatic control requirement；
4, the organic sludge that organic sewage generates after processing has certain viscosity, and dehydrating effect is not good enough, and easily blocking filter
Cloth.
Summary of the invention
A kind of effective and treatment effect is provided purpose of the utility model is to solve above-mentioned the deficiencies in the prior art
The processing system of good printed wiring board organic sewage.
To achieve the goals above, a kind of processing system of printed wiring board organic matter water designed by the utility model,
Including catch basin, conditioning tank, composite wastewater conditioning tank, copper-stripping reaction slot, first stage precipitation tank, contact break reactive tank, sulphur removal reactive tank,
Flocculation reaction slot, second-level settling pond, biochemical reaction tank, sludge concentration tank are equipped in the conditioning tank, comprehensive and sewage conditioning tank
Boring aeration device, the copper-stripping reaction slot, sulphur removal reactive tank, are respectively arranged with mechanical stirring in flocculation reaction slot at contact break reactive tank
Machine is respectively arranged with gear mud inclined tube in sedimentation basin level-one and sedimentation basin second level and adds to the materialization sludge pipe of sludge concentration tank, institute
It states and diving mixer, microporous aeration disc and sludge pump is housed in biochemical reaction tank and added to the biochemical spoil disposal of sludge concentration tank
Pipe.
A kind of processing system for printed wiring board organic sewage that the utility model obtains, technical effect have following five
Point:
1, the independent pretreatment unit of leading portion complexity in conventional treatment method can be saved, organic sewage need not be using acid
Analysis, the pretreatment of coagulation, precipitation and separation, simplify technique, and save one-time investment expense；
2, organic sewage is alkalinity, and PH higher can be used to adjust the pH value of composite wastewater (PH is acidity), save a large amount of medicines
Agent expense；
3, the content of organics in organic sewage is higher, can be provided more carbon in biochemical reaction tank denitrification
Source, so that its denitrification better effect, the additional amount of carbon source when reducing script denitrification；
4, flocculation sedimentation, sludge mix organic sewage with copper-contained sludge together with other sewage in copper-stripping reaction slot,
Better effect when sludge dewatering；
5, it is verified through longtime running, the microorganism in the system mesophytization reaction tank can be degraded well in organic sewage
Organic matter, because the proportion of organic sewage is different, the composite wastewater COD after pretreatment is generally 400-800mg/l, raw
60-100mg/l can be down to by changing reaction tank water outlet COD, and removal rate adds proper amount of carbon source, the removal rate of total nitrogen can up to 85% or more
Reach 90% or more.
