Waste water processes certain automobile factory's application phosphorized waste water of example 1 and processes
Certain automobile factory builds a waste water integrated treatment station, owing to phosphorized waste water containing the heavy metal such as nickel, zinc,
According to environmental requirement, could mix with other waste water after needing independent pretreatment, carry out biochemical treatment the most again,
Design phosphorized waste water processes the integrated multi-functional wastewater treatment equipment using this use novel, and design provides waste water
Main contamination index and water outlet require such as following table:
| Major pollutants | PH | CODCr | Zn2+ | Ni2+ | PO4 3- | Remarks |
| Unit | / | mg/L | mg/L | mg/L | mg/L | |
| Design water inlet data | 4-5.5 | 280 | 5 | 15 | 130 | |
| Design water number evidence | 6-9 | ≤150 | ≤1.0 | ≤0.5 | ≤0.5 |
Note: design water number according to being country's " integrated wastewater discharge standard " (GB8978-1996) first grade discharging
Standard
Multistage selective response district, according to waste water characteristic, is divided into by integrated multi-functional equipment by three deflectors
Four reaction areas
Wherein nickel and zinc use hydroxide precipitation method, and phosphate radical uses calcium phosphate precipitation, and coordinative composition of equipments adds four
Planting medicament, be Calx, Caustic soda, ferrous sulfate and polyacrylamide respectively, these four medicament all uses and adds
Medicine device is allocated as water preparation, uses dosing pump to add.
Waste water initially enters a reaction zone in multistage selective response district, adds lime cream in a reaction zone,
Control pH value about 7.0, make the phosphate in waste water all react generation calcium phosphate granules with lime cream, keep away
Exempt to disturb heavy metal reaction；Then No. two reaction zones add alkali liquor, control pH value about 9.5, make in waste water
Zinc ion and hydroxide ion react generation zinc hydroxide, nickel ion reacts generation hydroxide with hydroxide ion
Nickel, the pH value precipitating needs due to nickel hydroxide completely is 9.5, zinc hydroxide precipitates the pH value of needs completely
Being 8.0 (returning molten pH value is 10.5), therefore in No. two reaction zones, zinc and nickel are reacted completely；Three
Number reaction zone adds ferrous sulfate, and ferrous sulfate is slightly acidic coagulant, can the particulate matter that generates of reaction
Cohesion is got up, simultaneously ensure not return molten on the premise of waste water pH value returned be adjusted to slightly below 9；Anti-at No. four
Answering district to add PAM flocculant, condensation product enters high-efficiency pipe chute sedimentation tank after generating oarse-grained alumen ustum.
Waste water is reacted, coagulation, after flocculation by tube settler water distributor water distribution, through flap district current stabilization with enter
One step flocculation, subsequently into tube settling district, is precipitated in settling zone, the agglutinating matter of removable 95%,
Fine filtering district is entered after water collecting dike is collected.
Waste water through antipriming pipe water distribution uniformity, then filters out remaining through purity quartzite filtering area in fine filtering district
Subparticle, water outlet enter rear class system.
After equipment investment runs, owing to factory's discontinuity has a large amount of etching waste liquor to be mixed in waste water, therefore actual useless
Water influent quality exceedes design load, and change of water quality is relatively big, and after integration apparatus processes, effluent quality refers to
Mark controls, in following indication range, to see table the most all the time:
| Major pollutants | PH | CODCr | Zn2+ | Ni2+ | PO4 3- |
| Unit | / | mg/L | mg/L | mg/L | mg/L |
| Actual water inlet data | 3-5.5 | 220-660 | 8-25 | 18-45 | 80-120 |
| Actual water outlet data | 8-9 | 40-80 | ≤0.5 | ≤0.1 | ≤0.2 |
| Design water number evidence | 6-9 | ≤150 | ≤1.0 | ≤0.5 | ≤0.5 |
Note: design water number according to being country's " integrated wastewater discharge standard " (GB8978-1996) first grade discharging
Standard
Actual motion water outlet is better than country " integrated wastewater discharge standard " (GB8978-1996) one-level row all the time
Putting standard, therefore this waste water can process directly discharge without rear class after treatment, is much better than design requirement.
Waste water processes example 2, and certain processes containing various heavy waste water such as chromium are nickeliferous
A waste water processing station is built in certain factory's nickel and cobalt extraction workshop, and wastewater source mainly returns at leaching, electrolysis, cobalt
Receive and the waste water of laboratory discharge, waste water mainly contains Ni2+、Cd2+、Cr6+、Pb2+、Cu2+、Zn2+
Etc. several Heavy Metallic Elements (similar electroplating wastewater, complexity is more than electroplating wastewater), owing to factory's age is longer,
All kinds of waste water dual disposals, therefore process to waste water and bring great difficulty, be now designed with integrated many merits
Energy wastewater treatment equipment, design provides the main contamination index of waste water and water outlet to require such as following table:
| Major pollutants | PH | SS | Zn2+ | Ni2+ | Cd2+ | Cr6+ | Cu2+ | Pb2+ |
| Unit | / | mg/L | mg/L | mg/L | mg/L | mg/L | mg/L | mg/L |
| Design water inlet data | 7-9.5 | / | 5 | ≤40 | ≤10 | ≤30 | ≤5 | ≤5 |
| Design water number evidence | 6-9 | ≤80 | ≤1.0 | ≤0.5 | ≤0.08 | ≤0.4 | ≤0.5 | ≤0.8 |
Note: designing water number evidence for producer according to local environmental requirement, processed waste water enters municipal sewage pipe network
Owing to containing Cr VI in waste water, Cr VI is extremely toxic substance, according to code requirement, need to be reduced to
After trivalent chromium again with other a huge sum of money waste water be uniformly processed, integrated multi-functional equipment according to this feature of waste water,
Multistage selective response district is divided into four reaction areas by three deflectors, supporting adds five kinds of medicaments, sulfur is set
Acid, sodium sulfite, Calx, ferrous sulfate and polyacrylamide, these five kinds of medicaments all use dosing to fill
Put and be allocated as water preparation, use dosing pump to add.
Waste water initially enters reaction zone, selective response pond one, and a reaction zone adds hydrochloric acid, synchronizes to add sulfurous
Acid hydrogen sodium, controls pH value 2.5-3.0, between ORP value 200-300MV, under this reaction condition, six
Valency chromium is reduced to rapidly trivalent chromium, and then No. two reaction zones add lime cream, control pH value about 7.0, make
Copper ion in waste water, trivalent chromium all react generation hydroxide particles with lime cream, it is to avoid interference rear class is anti-
Should；Then No. three reaction zones continuously add lime cream alkali liquor, control pH value about 9.5, make remaining in waste water
Heavy metal cation and hydroxide ion total overall reaction generate hydroxide precipitation；Sulfur is added No. four reaction zones
Acid is ferrous, PAM flocculant, and ferrous sulfate is slightly acidic coagulant, the particulate matter that can reaction be generated
Cohesion is got up, simultaneously ensure not return molten on the premise of waste water pH value returned be adjusted to slightly below 9；PAM flocculates
Agent flocculation condensation product enters high-efficiency pipe chute sedimentation tank after generating oarse-grained alumen ustum.
Waste water is reacted, coagulation, after flocculation by tube settler water distributor water distribution, through flap district current stabilization with enter
One step flocculation, subsequently into tube settling district, is precipitated in settling zone, the agglutinating matter of removable 95%,
Fine filtering district is entered after water collecting dike is collected.
Waste water through antipriming pipe water distribution uniformity, then filters out remaining through purity quartzite filtering area in fine filtering district
Subparticle, water outlet enter rear class system.
Equipment investment runs, and after integration apparatus processes, effluent quality index controls the most all the time following
In indication range, see table:
| Major pollutants | PH | SS | Zn2+ | Ni2+ | Cd2+ | Cr6+ | Cu2+ | Pb2+ |
| Unit | / | mg/L | mg/L | mg/L | mg/L | mg/L | mg/L | mg/L |
