Problems solved by technology

[0002] Hardware is obtained through mechanical processing. Hardware is widely used in daily life. Hardware can be recycled and reused, which is of great significance to sustainable development. During the recycling process of hardware, pickling is often used It is used to derust the surface of hardware. The main component of pickling solution is dilute hydrochloric acid. Used separately, the production cost is high, causing a lot of waste, and has great limitations. There is a lack of oxidation and adsorption particles for rust removal and pickling waste liquid treatment to solve the above problems

Abstract

The invention discloses oxidation and absorption particles for treatment of rust-removing pickling waste liquid, and a production method of the oxidation and absorption particles. Aluminium polychlorid, limestone, iron-free aluminum sulfate powder, iron sulfate, sodium hypochlorite, bentonite, activated carbon and distilled water are used as raw materials, the proportion of all the components is strictly controlled, and the traditional way of separately using an oxidant and an adsorbent is changed; the prepared particles have the functions of oxidation and absorption at the same time, so thatthe treatment cost is greatly reduced; the bentonite is wide in source; the finished product material is granular, and is easy to store, long in shelf life, simple in the preparation process and goodin use effect; the water temperature is easily controlled by using a water bath heating way, so that the temperature environment of preparation is guaranteed, and the performance of the finished product is more stable; a drum type mixer is used for continuously overturning so as to effectively prevent the particles with higher density from sinking into the lower layer, thus guaranteeing the mixingquality; the mixture, which does not pass through a sieve, is enabled to pass through the sieve in a way of being repeatedly ground with force, so that material waste is avoided.

Description

technical field [0001] The invention relates to the technical field of recycling and processing of hardware, in particular to oxidation and adsorption particles for rust removal and pickling waste liquid treatment and a manufacturing method thereof. Background technique [0002] Hardware is obtained through mechanical processing. Hardware is widely used in daily life. Hardware can be recycled and reused, which is of great significance to sustainable development. In the process of recycling hardware, pickling is often used It is used to derust the surface of hardware. The main component of pickling solution is dilute hydrochloric acid. Used separately, the production cost is high, causing a lot of waste, and has great limitations. Now there is a lack of oxidation and adsorption particles for rust removal and pickling waste liquid treatment to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in th...
