Abstract
The utility model provides a waste water and heavy metal recycling device. The waste water and heavy metal recycling device comprises a waste water tank and a filtering water tank which are connected through a pipeline, as well as a raw water pump for feeding the waste water from the waste water tank into the filtering water tank. The waste and heavy metal recycling device is characterized by also comprising a nanofiltration membrane recycling device and a nanofiltration high-pressure pump for feeding the waste water from the filtering water tank into the nanofiltration membrane recycling device, wherein the nanofiltration membrane recycling device uses the nanofiltration membrane as the separating medium. According to the waste water and heavy metal recycling device, waste water containing heavy metal and heavy metal generated in the production process are recycled, so that water resources are saved, and the environment is protected; by using the novel nanofiltration membrane, the reject rate on the divalent heavy metal salt such as sodium sulfate and nickel sulfate reaches 99%, and the reject rate on low-valent salt such as sodium chloride is only 50% below (the ordinary RO membrane is 99%). Thus, the recycling device is particularly suitable for heavy metal waste water of two valences above, and the recycling efficiency is high.

The utility model content
At above-mentioned defective of the prior art, the utility model provides a kind of waste water efficient, environmental protection to reach wherein heavy metal collection system.
The utility model provides a kind of waste water to reach wherein heavy metal collection system, it comprises the wastewater disposal basin and the water tank with strainer of pipe connection, reach the raw water pump of the waste water in the described wastewater disposal basin being sent into described water tank with strainer, it is characterized in that: it also comprises the nanofiltration membrane retrieving arrangement and the waste water in the described water tank with strainer is sent into the nanofiltration high-pressure pump of described nanofiltration membrane retrieving arrangement, adopts nanofiltration membrane as separating medium in the described nanofiltration membrane retrieving arrangement.
Preferably, the pipeline between described water tank with strainer and the raw water pump is provided with accurate filter.
Preferably, described nanofiltration membrane retrieving arrangement connects fresh water water shoot and concentrated water drainage water pipe, described concentrated water drainage water pipe one end connects the described water tank with strainer the other end by reuse water pipe connection production system, and described fresh water water shoot is by reuse water pipe connection production system.
Preferably, described fresh water water shoot is provided with the conductance measurement instrument.
Preferably, be provided with ball float flowmeter on the pipeline between described wastewater disposal basin and the described water tank with strainer and described fresh water water shoot and the concentrated water drainage water pipe.
Preferably, be provided with pH value transmitter in the described water tank with strainer.
The waste water that the utility model provides and wherein waste water and the heavy metal in heavy metal collection system the heavy metal-containing waste water that production link is produced reclaim respectively, saved water resources, protected environment; The nanofiltration film that it adopted, rejection to two valency heavy metallic salts such as sodium sulfate, single nickel salts reaches 99%, and only be (common RO film is 99%) below 50% to holding back of low price salt such as sodium-chlor, therefore the utility model reclaims the above heavy metal wastewater thereby of two valencys and has more specific aim, and organic efficiency is higher.
