Problems solved by technology

Because the particles of the nanocomposite adsorbent are very small, it is difficult to separate the used nanocomposite adsorbent from water, and it cannot be reused. The adsorbed nanocomposite adsorbent is likely to cause secondary pollution. Therefore, industrial heavy metal Wastewater treatment costs are high and usage is restricted

Abstract

The invention relates to the technical field of wastewater treatment equipment, in particular to heavy metal wastewater treatment equipment and a treatment method. The equipment for treating heavy metal wastewater includes a raw material liquid delivery system, a heavy metal adsorption system, a heavy metal analysis system, a filtrate delivery system, and a concentrated liquid reuse system; the raw material liquid delivery system sends wastewater containing heavy metals into the heavy metal adsorption system; the heavy metal There is at least one set of adsorption system; the heavy metal analysis system includes a gas tank and a high-pressure gas supply device, and the gas tank is connected to the outer barrel through a high-pressure gas supply device; the filtrate delivery system and the concentrate recovery system are respectively connected to the water outlet of the water outlet pipeline . The above-mentioned heavy metal wastewater treatment equipment and method can realize the repeated use of nano-adsorbents and heavy metal ions, have good sewage treatment effect, large adsorption capacity, high analysis efficiency, will not cause secondary pollution, and have wide practicability.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to heavy metal wastewater treatment equipment and a treatment method. Background technique [0002] For low-concentration heavy metal wastewater, currently commonly used treatment methods include adsorption method and ion exchange method. Due to the interference of high salinity and high organic matter in wastewater, these methods cannot selectively adsorb chromium. and high operating costs, complex operations and other issues. With the development of nanotechnology, the development of nanomaterials has become a research hotspot, and organic-inorganic nanocomposites show special advantages in the specific adsorption of chromium. [0003] In order to solve the above problems, the invention patent application with the application publication number CN 103450393 A discloses a preparation method of a nanocomposite adsorbent for directly treating chromium-containi...
