Receive strain the device by the wide application in pure water purification unit, like food water, well water purification etc. The utility model discloses in using waste water treatment with it, the waste water after the retreatment reaches five types of water emission standard on the earth's surface moreover breakthroughly, simultaneously, the utility model discloses a water processing system still moves domestic sewage and gets into the equalizing basin together and handle, has reduced the running cost.

Description

Adopt the Waste Water Treatment of nanofiltration device

Technical field

The utility model relates to technical field of waste water processing, particularly relates to a kind of Waste Water Treatment adopting nanofiltration device.

Background technology

The source of electroplating wastewater is generally: (1) plating piece rinse water; (2) spent plating bath; (3) other waste water, comprise and wash away mill floor, scrub pole plate wash water, ventilation installation water of condensation, and due to the various tank liquor of coating bath seepage or operational administrative improper " run, drip, leak " that cause and draining; (4) component cooling water, water coolant in use, except temperature raises, is polluted.The water quality of electroplating wastewater, the water yield and the processing condition of Electroplating Production, the factors such as load, operational administrative and water use model of producing are relevant.

Only can reach terrestrial reference three class water quality standard after current electroplating wastewater processing, along with environmental pollution states is more serious, done further raising to the emission standard of sewage, emission standard is risen to earth's surface five class water quality standard by the water extraction meeting terrestrial reference three grades by some areas; The COD that electroplating wastewater after process premenstruum is this kind of, the sewage that ammonia-nitrogen content is not too high, though existing sewage disposal device can be good at removing COD and ammonia nitrogen, but the content in its water outlet is very little can not reach again earth's surface five class water quality standard.

Utility model content

The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of Waste Water Treatment adopting nanofiltration device.

The technical scheme adopted for realizing the purpose of this utility model is:

A kind of Waste Water Treatment adopting nanofiltration device, comprise equalizing tank, be arranged in described equalizing tank in order to by sewage lifting to the lift pump in anaerobic pond, the Aerobic Pond be communicated with through overflow port with anaerobic pond successively, MBR pond, settling tank and clean water basin, and the deep bed filter, accurate filter, high-pressure pump and the nanofiltration device that are communicated with by the road with described clean water basin successively, the product mouth of a river of described nanofiltration device connects discharge outlet, and dense water side is back to equalizing tank through return line.

Described equalizing tank also comprises sanitary sewage access pipeline.

Elastic solid filler is provided with to increase the area of biological in described Aerobic Pond.

Described settling tank is inclined tube-type or ramp type settling tank.

Between described MBR pond and Aerobic Pond, be provided with sludge refluxing apparatus, described sludge refluxing apparatus comprises the sludge reflux pump be arranged on bottom MBR pond, the sludge reflux pump described in connection and the mud return line of Aerobic Pond.

Compared with prior art, the beneficial effects of the utility model are:

Nanofiltration device is widely used in pure water equipment, as food water, well water purification etc., the utility model applies it in wastewater treatment breakthroughly, and the waste water after reprocessing reaches earth's surface five class water emission standard, meanwhile, water treatment system of the present utility model is also run sanitary sewage and is entered equalizing tank together and process, and decreases running cost.

Accompanying drawing explanation

Figure 1 shows that the structural representation of the Waste Water Treatment of employing nanofiltration device of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, the Waste Water Treatment of employing nanofiltration device of the present utility model comprises and the equalizing tank 1 producing water and sanitary sewage after electroplating wastewater processing and be communicated with by the road, be arranged in described equalizing tank 1 in order to by sewage lifting to the lift pump 12 in anaerobic pond, the Aerobic Pond 3 be communicated with through overflow port with anaerobic pond successively, MBR pond 4, inclined tube-type or ramp type settling tank 5 and clean water basin 6, and the deep bed filter 7 be communicated with by the road with described clean water basin successively, accurate filter 8, high-pressure pump 9 and nanofiltration device 10, the product mouth of a river of described nanofiltration device connects discharge outlet, dense water side is back to equalizing tank through return line 11.Wherein, elastic solid filler is provided with in described Aerobic Pond to increase the area of biological.Meanwhile, the aeration tube be communicated with gas blower is provided with bottom described Aerobic Pond.

First sewage enter in equalizing tank and carry out entering anaerobic pond after homogeneous is all measured and carry out anaerobic reaction, the material of macromolecular substance and difficult degradation is decomposed, for aerobic reaction provides better basis, after through the aerobic reaction of Aerobic Pond and MBR, organism is decomposed, clear water after precipitation, again by filtering, and five class water quality standards after nanofiltration process, can be reached, and the dense water of nanofiltration is got back in equalizing tank and is processed.

The utility model adopts nanofiltration device to carry out reprocessing to waste water not yet up to standard after sewage disposal device process, it is made to reach the water quality requirement of earth's surface five class water, its advantage be can organics removal, bacterium, outside virus, lower to inorganics clearance, avoiding problems the dense water that nanofiltration device produces causes saltiness to raise when returning equalizing tank, affect the microorganism growth of sewage disposal device, realize an optimum cycle for the treatment of.

Specifically, described nanofiltration device comprises the nanofiltration membrane that three groups of series-parallel connection are arranged, wherein, the influent side of first group and second group nanofiltration membrane directly connects high-pressure pump, the influent side of the 3rd group of nanofiltration membrane is connected with the dense water side of first group and second group nanofiltration membrane, the dense water side of the 3rd group of nanofiltration is communicated with return line, and water producing pipe is also accessed in the product water side of first group and second group and the 3rd group nanofiltration membrane.

Preferably, between described MBR pond and Aerobic Pond, be provided with sludge refluxing apparatus, described sludge refluxing apparatus comprises the sludge reflux pump 12 be arranged on bottom MBR pond, the sludge reflux pump described in connection and the mud return line of Aerobic Pond.By the partial sludge in MBR pond is back in Aerobic Pond, the sludge concentration in Aerobic Pond and activity can be ensured, improve processing efficiency, simultaneously, described anaerobic pond, Aerobic Pond, MBR pond, settling tank and clean water basin entirety are positioned at the space of a rectangular parallelepiped, there is public pool wall between each pond and pond, effectively can reduce the civil engineering part of equipment and adding of pipeline like this, saved cost.
