Accompanying drawing explanation
Fig. 1 is the one-piece construction block diagram of the full automatic processing equipment of high density nickel-containing waste water.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1, the full automatic processing equipment of a kind of high density nickel-containing waste water that the utility model provides, comprise following multiple equipment, these equipment are all pass through pipeline communication, specific as follows: an adjustment pond, waste water divides three portion collection to adjusting pond, one is RO washing waste water, chemical nickel plating plating tank waste water and anodized waste water three are directly delivered to adjustment pond, two is that the hanger pickling waste waters that concentration is high bit by bit delivers to adjustment pond by the storage tanks of otherwise designed, three is that the draining that in each strainer back washing and dehydration equipment, sludge dewatering equipment dehydration produces returns to adjustment pond.Three effluent part pass through aeration Homogeneous phase mixing in adjustment pond.
A pH being added with milk of lime adjusts pond, and by adjustment pond lift pump, adjustment Chi Shui is promoted to a pH by design discharge and adjusts in pond, the acid in lime slurry neutralization waste water, makes the nickel in waste water precipitate with the formation of oxyhydroxide;
The 2nd pH being added with NaOH medicament adjusts pond, adjusts the waste water of pond neutralization precipitation through a pH, flows into the 2nd pH and adjusts in pond, ensure the pH value of former water;
First flocculation basin being added with heavy metal chelating agent and coagulating agent, described 2nd pH adjusts the first flocculation basin of the wastewater streams warp in pond, utilizes compendency, accelerates reaction precipitation speed, makes the nearlyer step coagulative precipitation of the nickel in waste water; Can also arrange further between the first described flocculation basin and settling tank and also be provided with the second flocculation basin, accomplish better coagulative precipitation;
A settling tank, through the first flocculation basin sewage self-flowing to settling tank, the throw out produced through the first flocculation basin aggegation precipitates at this, form mud, settling tank comprises the sludge sump for storing mud, and sludge sump rear end is also provided with the dehydration equipment carrying out processed, mud is delivered to pressure filter from bottom, carry out processed by dehydration equipment, the mud dewatered here can be transported outward, and dehydration filtrate can continue to be drained in adjustment tank.
A sand-bed filter, this sand-bed filter is connected with above-mentioned settling tank, and settling tank supernatant liquid flows into sand-bed filter, the removals such as the suspended particle do not precipitated by settling tank and colloid organism, in order to avoid pollute the ion-exchange of rear end.Sand-bed filter is connected with and send wetting system.
Further, described sand-bed filter and send between wetting system and be connected with Zeo-karb system; Finally adopt and finally can process the Zeo-karb system that nickel carries out adsorption selection, removed completely by the nickel in process water, make it reach emission standard, the water after process being terminated by sending wetting system is promoted by pump and enters comprehensive wastewater treatment plant.Further, described sand-bed filter comprises the pressure warning unit and the time relay that control the positive backwash of sand-bed filter, accomplishes intellectuality, reduces labor force.
Produce waste water for the nickeliferous acid-bearing wastewater of plating.Its pH is lower, and Ni content is higher, and biodegradability is poor, and the main Environmental capacity factor is: Ni, COD, NH
3-N, pH etc.This waste water station engineering design basic data and waste water index in requirement are as following table:
| Project | pH | COD | Ni | NH 3-N | Total phosphorus | TDS |
