Abstract
The invention discloses a harmless disposal method for solid hazardous waste phosphated residue, and the harmless disposal method comprises the following steps: (1), removing impurities; (2), ball-milling in a ball mill according to the proportion that: phosphated residue to water equals to 1 to 1-2, milling until the phosphated residue is equal to or greater than 400 meshes; (3), carrying out liquid-solid separation; (4), carrying out drying treatment to the solid until the moisture content is lower than 1 percent, and using the dried solid as a rust-proof filler; (5), carrying out concentration treatment to the liquid so as to use the liquid as a replenisher for a phosphating solution. The harmless disposal method provided by the invention has the technical effects that effective components in the phosphated residue are fully used, secondary pollution cannot be produced during the treatment process, and the harmless disposal method has obvious environmental protection benefits and economic benefits.
Description
Technical field
The present invention relates to a kind of method for innocent treatment of solid hazardous waste material phosphatization slag.
Background technology
Phosphatization is conventional process for treating surface, in industry extensive application such as automobile, chemical industry, boats and ships, space flight and aviation and household electrical appliance.The deposit producing in parkerizing process is phosphatization slag, belong to solid hazardous waste material, refuse classification is: HW17 surface treatment waste, and refuse code is: 346-064-17, through chemically examining its composition containing Fe (+3) 27.5%, Zn (+2) 2.35%, PO
4(3) 51.8%; These slags of past are dropped or with water discharge, cause environmental pollution.And existing processing method to phosphatization slag is to adopt NaOH neutralisation, the method will consume a large amount of energy and water And produces a large amount of alkaline waste waters, environment is caused to secondary pollution, and meanwhile, the investment of the method treatment facility is large, floor space is large, disposal cost is high, processes product tertiary sodium phosphate value not high, causes larger financial burden to enterprise.
Summary of the invention
The object of this invention is to provide a kind of method for innocent treatment of solid hazardous waste material phosphatization slag.
Technical scheme of the present invention is, a kind of method for innocent treatment of solid hazardous waste material phosphatization slag:
(1), removal of impurities;
(2), in phosphatization slag: water=1: 1～2 ratio ball milling in ball mill, is milled to phosphatization slag >=400 order;
(3), liquid-solid separation;
(4), solid is dried to processing, reach moisture below 1%, as antirust filler;
(5), liquid is carried out to concentration, as the supplementary liquid of Phosphating Solution.
The present invention has following technique effect, can make full use of the active ingredient in phosphatization slag, and processing procedure can not produce secondary pollution, has obvious environmental benefit and economic benefit.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
The specific embodiment
As shown in Figure 1, a kind of method for innocent treatment of solid hazardous waste material phosphatization slag, gets the phosphatization slag in certain auto producer phosphatization workshop, through this phosphatization slag is analyzed, and Fe
+ 328.5%, Zn
+ 23.2%, phosphate radical PO
4 -352.8%, all the other are impurity;
(1), removal of impurities;
(2), in phosphatization slag: water=1: 1～2 ratio ball milling in ball mill, is milled to phosphatization slag >=400 order;
(3), liquid-solid separation;
(4), solid is dried to processing, reach moisture below 1%, 400 orders sieve, containing Fe
+ 345%, containing Zn
+ 220%, as antirust filler, tail over part and return to ball mill continuation ball milling;
(5), liquid is carried out to multi stage precipitation, vacuum filtration removal of impurities, heating is concentrated, phosphorous acid group PO
4 -3the 70% supplementary liquid as Phosphating Solution.
Claims (1)
1. a method for innocent treatment for solid hazardous waste material phosphatization slag, is characterized in that:
(1), removal of impurities;
(2), in phosphatization slag: water=1: 1～2 ratio ball milling in ball mill, is milled to phosphatization slag >=400 order;
(3), liquid-solid separation;
(4), solid is dried to processing, reach moisture below 1%, as antirust filler;
(5), liquid is carried out to concentration, as the supplementary liquid of Phosphating Solution.
