Embodiment 1

[0046] When the treatment method of jade processing wastewater described in the present invention is used in a treatment device with a daily treatment capacity of 800 tons of wastewater, the treatment process is: S01 slag removal—S02 oil separation—S03 heavy metal removal, decolorization—S04 solid suspended matter removal, and turbidity removal degree—S05 re-purification—S06 disinfection, discharge—S07 sludge treatment; for specific operations, it should be noted that due to the large daily processing volume, the total nitrogen, total phosphorus or chemical oxygen demand in the water treated by S04 did not reach According to the discharge standard, the water discharged from the purification tank is transported to the integrated bioreactor. The integrated bioreactor is equipped with a membrane module, and fillers are added to the integrated bioreactor. Under the action of negative pressure, the membrane The components filter the effluent; in addition, in the S06 disinfection ste...

Embodiment 2

[0051] When the treatment method of jade processing wastewater according to the present invention is used in a treatment device with a daily treatment capacity of 60 tons of wastewater, the difference from Example 1 is that the above-mentioned S05 re-purification step is canceled, and the treatment process is: S01 slag removal-S02 Oil separation—S03 to remove heavy metals, decolorization—S04 to remove solid suspended matter, deturbidity—S06 disinfection, discharge—S07 sludge treatment.

[0052] Both the swirling filter membrane purification tank and the integrated bioreactor of the present invention are provided with a dispensing system and a dosing system; An upper and lower double circulation stirring dispensing system, the patent publication number of which is CN203360030U discloses a water treatment dosing system.

[0053] The mechanical grill sump, automatic oil separator, swirl filter membrane purification tank and integrated bioreactor involved in the present invention ...

Abstract

The invention relates to a treatment method of processing wastewater of jade. The treatment method at least comprises the following steps: S01 deslagging, S02 oil separating, S03 heavy metal removal, and decoloration, S04 solid suspended matter and turbidity removal, S05 re-purifying, S06 disinfecting and discharging, and S07 sludge treating. The treatment method has the excellent effects that an oil and water separation rate is increased, and an oil removal rate is greater than 90% by an air floatation mode via an air floatation oil separation tank; with the adoption of a pipeline coagulation technology, removal of heavy metals and the decoloration are realized, a removal rate of the heavy metals is greater than 90%, and a decoloration rate is greater than 98%; matter-liquid separation is realized by a spiral-flow filter membrane purification can, a removal rate of solid suspended matters is greater than 99%, and an improvement rate of turbidity is greater than 98%; and with the adoption of an integral bioreactor, COD (Chemical Oxygen Demand), ammonia nitrogen and total phosphorus in the processing and production wastewater of the jade reach level I of the national rural drainage standard.

Description

technical field [0001] The invention belongs to the field of environmental engineering, and in particular relates to a treatment method for stone processing wastewater based on physical degreasing technology, chemical decolorization technology, chemical heavy metal removal technology, physicochemical technology and MBR technology, in particular to a treatment method for jade processing wastewater. Background technique [0002] In recent years, with the rising price of jade, more and more various jade processing enterprises have been established, and the output of jade has also increased significantly. A large amount of wastewater will be generated in each link, and the wastewater generated in each link will be combined together, with deep color, high acidity, high content of suspended solids and organic matter. Although the amount of wastewater discharged by a single enterprise every day is not too large, the total amount of wastewater discharged by hundreds of thousands of ...
