[0005] In this scheme, although the lower surface of the π-allylnickel compound-containing modified diatomite adsorption membrane laid on the top of the wastewater inside the adsorption chamber can adsorb mineral oil, it is difficult for the adsorption membrane to be artificially turned in the adsorption chamber. Therefore, it is difficult to effectively utilize the upper surface of the adsorption film, and the adsorption film floating on the surface of the wastewater is prone to unstable movements under the action of the outside world, which in turn affects the utilization rate of the adsorption film and the adsorption of mineral oil.

Embodiment approach
[0034] As an embodiment of the present invention, the top end of the No. 2 pneumatic push rod 3 is movably connected to the bottom end of the support plate 31; The end of the push rod 43 is installed with an electromagnet 44 capable of adsorbing the outer end sidewall of the support plate 31; during operation, in order to facilitate adsorption of mineral oil containing π-allyl nickel compound modified diatomite adsorption film 24 It can automatically move to the position of the collection chamber 4. At this time, the controller first controls the No. 1 pneumatic push rod 2 and the No. 2 pneumatic push rod 3 to drive the above-mentioned adsorption film to move to the position of the cavity of the adsorption chamber 1, and make the support plate. The outer side of the 31 is flush with the electromagnet 44 at the end of the No. 3 pneumatic push rod 43. At this time, the controller controls the No. 3 pneumatic push rod 43 to drive the electromagnet 44 to move to the outer side of t...

The invention belongs to the technical field of waste water treatment, and specifically relates to a process for treating industrial waste water containing oil and heavy metals; in the process, a group of ultra-fine bubble generators are installed on the bottom surface of the adsorption chamber, and the adsorption chamber is close to the top of the side wall of the water inlet pipe. A No. 1 pneumatic push rod is installed, and the top of the No. 1 pneumatic push rod is provided with a No. 1 motor and a rotating frame, and the rotating frame is internally connected with a rotating cylinder and a modified diatom containing π-allyl nickel compound on its side. Soil adsorption film, No. 2 pneumatic push rod is installed on the other side wall of the adsorption chamber, the top of the No. 2 pneumatic push rod is provided with a rotating plate; one side of the adsorption chamber is provided with a collection chamber, and the collection chamber There is a membrane frame on the side wall; the present invention flips the adsorption membrane adsorbed with mineral oil by setting a turning mechanism on the top of the adsorption chamber, which greatly improves the adsorption effect and utilization rate of the mineral oil on both sides of the adsorption membrane; and can effectively Improve the treatment quality and treatment effect of industrial wastewater.
Description
technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a process for treating oily heavy metal industrial wastewater. Background technique [0002] Heavy metal pollution refers to the environmental pollution and ecological damage caused by heavy metals and their compounds. The degree of harm depends on the concentration and chemical forms of heavy metals in the environment, food and organisms. Heavy metal pollution is mainly manifested in water pollution, and part of it is in the air and solid waste. Heavy metal pollution is different from pollution from other organic compounds. Many organic compounds can be purified by physical, chemical or biological effects in nature to reduce or eliminate their hazards. Heavy metals are enriched and difficult to degrade in the environment. [0003] But now heavy metal ions often exist in oily wastewater, and the presence of grease in the water seriously hinders the removal of heavy ...
