Crane electroplating wastewater treating agent capable of efficiently adsorbing metal ions and production method of agent

Abstract

The invention discloses a crane electroplating wastewater treating agent capable of efficiently adsorbing metal ions. Glass powder and iron oxide magnetic powder are modified and then added to raw materials to replace partial apatite, so that the exploitation quantity of natural apatite is reduced, and the adsorption performance of a product is effectively improved; meanwhile, sweet potato waste and coconut dust are organically modified, then used as a binder to be added to the raw materials and blended with an effective chemical adsorbent, the compatibility with organic pollutants is good, the adsorption rate for the organic pollutants is high, a binding body having rich pores and high strength is formed after treatment with granulation and high-temperature roasting technologies finally, a compound is formed by the added binder and other substances in the roasting process, the phase change of natural apatite powder in different temperature zones is inhibited, internal stress is reduced, and the pulverization degree is reduced; the produced treating agent has the efficient treating effect and the good adsorption performance, so that wastewater is discharged after reaching the standard; the agent is low in cost and high in practicability and has significant economic benefits.

Description

technical field [0001] The invention relates to the technical field of water treatment agents, in particular to a crane electroplating wastewater treatment agent capable of efficiently adsorbing metal ions and a preparation method thereof. Background technique [0002] With the continuous growth of my country's economy, my country's construction machinery industry is still in a period of rapid development in the future, especially the prospect of crawler crane industry is promising. The "Industrial Structure Adjustment Guidance Catalog (2011 Version)" promulgated by the National Development and Reform Commission clearly pointed out that crawler cranes of 400 tons and above were selected as "encouraged" products as an emerging industry, which indicates that crawler cranes have a bright future. More and more companies are joining the crane industry. Because cranes mostly work outdoors, special attention is paid to their surface treatment, including rust removal, electroplatin...

Problems solved by technology

Although the paper uses relatively cheap natural non-metallic minerals such as natural apatite as adsorption materials to remove heavy metal ions in wastewater, but consumes too many natural non-metallic minerals and belongs to non-renewable resources, which does not meet the requirements of green environmental protection and energy saving. The utilization rate of excess solid waste piled up by many processing enterprises is not high, so it can be effectively utilized and modified to replace part of the natural apatite, and at the same time, an appropriate binder can be added to prepare a good performance, low pulverization degree, Wastewater treatment agent with strong adsorption performance

This not only solves the problem of improper treatment of a large number of solid wastes, but also provides a strong and effective solution to the defects of existing wastewater treatment agents such as high cost, poor treatment effect and low strength.
