Existing foam separation, processing when heavy metal wastewater thereby, is all independent art breading, to some comparatively complicated heavy metal wastewater therebies, deals with more difficultly, there will be into the phenomenon of water shakiness, and pneumatic flotation effect is also bad, can carry a large amount of waste water secretly.
This treatment system sharpest edges are by the system of MBR technique and foam separation process integration composition.
Utility model content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of membrane sepn and foam separation combined type heavy metal waste water treatment system are provided.
The utility model is achieved through the following technical solutions:
A kind of membrane sepn and foam separation combined type heavy metal waste water treatment system, include the MBR system and the foam separator that cooperatively interact, it is characterized in that: described MBR system includes reactor body, in described reactor body, be provided with polyvinylidene fluoride hollow fiber pencil membrane module, the opening for feed of described reactor body is communicated with wastewater trough by pipeline, in described wastewater trough, is provided with agitator, described foam separator includes foam separation post, the opening for feed of described foam separation post is communicated with the discharge port of reactor body by pipeline, the bottom of described foam separation post is provided with gas separator, the inlet mouth of described gas separator is communicated with the air outlet of snubber by pipeline, and in pipeline, be provided with gas meter, the inlet mouth of described snubber is connected with humidifier by pipeline, in the intake ducting of described humidifier, be provided with air pump, the inlet mouth of air pump is communicated with the air outlet of reactor body by pipeline, and in pipeline, be also provided with gas meter, the spillway of described foam separation post is communicated with foam trap by pipeline.
Described polyvinylidene fluoride hollow fiber pencil membrane module is dipped in reactor body, lower end is provided with aeration tube so that water circulation power and the required oxygen of microorganism decomposing organic matter to be provided, be dipped in reactor body, in described polyvinylidene fluoride hollow fiber pencil membrane module, microfiltration membrane aperture is 0.1～0.2 μ m, and membrane filtration area is 0.2m
2.
Whole device is divided into MBR system and foam separation, and reactor body part is made by synthetic glass.MBR technique aeration tank, useful volume is 5L, hydraulic detention time is 5h left and right, built-in 1 polyvinylidene difluoride (PVDF) (PVDF) tubular fibre pencil film, microfiltration membrane aperture is 0.1～0.2 μ m, membrane filtration area is 0.2m
2.Film component device is dipped in reactor, and lower end is provided with aeration tube so that water circulation power and the required oxygen of microorganism decomposing organic matter to be provided, and has and utilize vibrated film surface to suppress that mud adheres to and the function of oxygen supply.MBR Process for Effluent enters in foam separation post, and bubbled gas is provided by air pump, takes into account valve through humidifier, snubber, flow, is entered in waste water by the gas distributor of flotation column bottom.Foam overflows through top, enters in foam trap.
The utility model has the advantages that:
(1) former water, after through MBR process acts, enters foam separation water quality and will be better than former water far away.
(2) investigate from bubbling effect aspect, in MBR reactor, metastable sludge concentration and sludge settling have guaranteed normal water inlet, have avoided the unstable phenomenon of intaking, thereby have greatly improved bubbling effect in pneumatic flotation post, have improved gas-liquid mass transfer efficiency.
(3) MBR inside reactor divides heavy metal to decompose, and has reduced to a certain extent gas-liquid mass transfer resistance, is conducive to alleviate the phenomenon that in pneumatic flotation post, bubble floating does not get up, and also greatly reduces foam and carries waste water secretly.
(4) if this technique is applied to Practical Project, can be in conjunction with seasonal water, raw water quality, simultaneously with reference to different water quality standard, suitably regulate hydraulic detention time, water outlet proportion and pneumatic flotation post operation conditions, reaching under the prerequisite of effluent quality standard, effectively reduce process costs.
