Embodiment Construction

[0046] In a specific embodiment of the present invention, the micro-electrolysis treatment system for treating acrylic wastewater includes a micro-electrolysis reaction unit, a neutralization precipitation unit, an improved biochemical unit, and a deep oxidation unit. Reduce power costs.

[0047] Micro-electrolysis reaction unit:

[0048] In the micro-electrolysis reaction unit, iron-carbon micro-electrode materials are used, and its specifications are: each group of materials includes 20 bags, and each bag is composed of 80x50 (1 bag) and 50x30 (2 bags).

[0049] The placement requirements of the microelectrode materials are: the supporting layer is covered, and the stacking is arranged in order of size, so that the waste water can fully contact with the materials.

[0050] In the above-mentioned micro-electrolysis reaction unit, several individual reaction cells are connected in series to form a group, and one or more groups are used to form a micro-electrolysis reaction un...

Abstract

The invention discloses a microelectrolysis treatment system for treating acrylon wastewater. The system sequentially comprises a microelectrolysis reaction unit, a neutralization and sedimentation unit and a biological treatment unit, wherein the microelectrolysis reaction unit comprises a plurality of independent microelectrolysis reaction tanks which are connected in series into one or more groups of microelectrolysis reaction units; each group of the microelectrolysis reaction tanks can operate independently; each independent microelectrolysis reaction tank adopts a bottom-inlet and top-outlet water inlet and outlet manner; a water distribution pipeline is arranged at the bottom of each microelectrolysis reaction tank, and used for driving water to move up spirally; a plurality of support layers are arranged in each microelectrolysis reaction tank; an acid microelectrode material is arranged on each support layer; an aeration and sludge discharging system is arranged at the bottom of each microelectrolysis reaction tank. The microelectrolysis treatment system has the advantages that ferrous sulfate generated in a microelectrolysis reaction can be utilized skillfully, hydrogen peroxide is added to obtain a Fenton reagent, so as to effectively remove various organic substances from the wastewater; moreover, as the microelectrode materials are arranged in a hydrolysis tank, an anaerobic tank and a contact oxidation tank, the difficulty of biochemical treatment is further reduced, and sludge loading is reduced.

Description

technical field [0001] The invention relates to the treatment of industrial wastewater, more specifically, the invention relates to a micro-electrolysis treatment system for treating acrylic wastewater. Background technique [0002] The chemical name of acrylic fiber is polyacrylonitrile fiber. Acrylic fiber is an important textile material, which can also be called "artificial wool" or "synthetic wool". It is characterized by softness, bright color, warmth and resistance to deformation. It is often used to make wool, blankets, sportswear, etc., with bright colors Bright, relatively low cost, far inferior to wool and pure cotton, but acrylic has good recovery performance, not easy to deform, and is much stronger than pure cotton. [0003] However, as an important petrochemical product, the wastewater produced in the acrylic fiber production process is highly toxic, highly polluting, and difficult to treat. [0004] In the prior art, a lot of research work has been done on ...
