Problems solved by technology

[0004] The problem with the above iron-carbon fillers is that the iron powder they use is uneven, the preparation conditions are harsh, and the sintering temperature is too high to cause the iron powder to oxidize and reduce the activity of the filler. In addition, the existing adhesives still have insufficient strength. , easy to decompose in water, affect the use of fillers and other shortcomings

Abstract

The invention discloses a method for preparing industrial waste water degraded micro-electrolytic iron-carbon filler, which comprises the following steps: (1) preparing a binder: mixing sodium silicate, calcium chloride and hydroxypropyl cellulose uniformly by weight, That is to get the binder; (2) mixing: put iron powder, activated carbon and binder into the mixer according to the weight ratio and mix evenly; (3) into balls: put the raw materials mixed in step (2) into the Form into balls in a ball machine; (4) Drying and molding: heat the balls obtained in step (3) to 250-300°C in a dryer to dry, and then they can be molded to obtain industrial wastewater degradable micro-electrolytic iron-carbon fillers . The preparation method is simple and reasonable, can be prepared in conventional equipment, and the conditions are mild; the micro-electrolytic iron-carbon filler for industrial pollutant wastewater degradation is spherical, has a large contact surface with sewage, and has good pollutant treatment effect. Industrial wastewater degrades micro-electrolytic iron-carbon fillers without hardening or passivation; the binder used is stable and not easy to hydrolyze.

Description

technical field [0001] The invention relates to a material for degrading industrial waste water pollutants, in particular to a preparation method for degrading micro-electrolytic iron-carbon fillers for industrial waste water. Background technique [0002] The iron-carbon filler is an iron-carbon primary battery composed of iron and carbon. In the absence of electricity, the metal iron forms the positive electrode, and the carbon forms the negative electrode to form the primary battery. A large number of positive electrodes and negative electrodes form a power grid according to a certain ratio. Filtration and electrolytic treatment of industrial wastewater to achieve the purpose of degrading organic pollutants. Further, iron and carbon can be slowly eliminated under the action of acid and alkali (and heavy metals), so as to achieve the purpose of sewage treatment. [0003] The invention patent with the publication number CN101486509 discloses a block micro-electrolytic fill...
