specific Embodiment approach

[0038] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: The present invention will be further described in detail below in conjunction with the examples.

Embodiment

[0039] Embodiment: as follows

[0040]

[0041] Explanation: 1, aluminum chloride described in the present invention is preferably to use polyaluminum chloride, aluminum iron silicate is polyaluminum iron silicate, and percarbonate is preferably sodium percarbonate. The above-mentioned components of the present invention are all commercially available.

[0042] 2. The coagulant aid used in the above-mentioned examples 1 and 2 of the present invention is compounded by organic synthesis of ethylenediamine and hydroxyethylidene diphosphoric acid with sodium gluconate in a ratio of 6:4 by mass . Examples 3 and 4 are compounded by organic synthesis of ethylenediamine and hydroxyethylidene diphosphoric acid with sodium gluconate in a mass ratio of 5:5. The ethylenediamine and hydroxyethylidene diphosphate are synthesized according to existing methods. The coagulant in the embodiment of the present invention adopts ethylenediamine and hydroxyethylidene diphosphoric acid to carr...

Abstract

The invention provides a treating agent for cleaning wastewater produced through machining. The treating agent comprises components in a mass ratio as follows: 10-15 parts of aluminum sulfate, 8-12 parts of aluminum ferric silicate, percarbonate, starch-acrylamide, 15.0-20.0 parts of a coagulant aid, 0.2-0.8 parts of alkyl aryl sodium sulfonate, alkyl glycoside FC-40, aluminum chloride and 2-8 parts of calcium chloride. The treating agent can effectively treat the cleaning wastewater produced through machining, the removal rate of CODcr in the treated wastewater can be up to 95% or higher, the total removal rate of COD can be up to 98% or higher, the usage of the treating agent is low, the wastewater treatment speed is high, and the comprehensive use cost is low.

Description

Technical field: [0001] The invention relates to a wastewater treatment agent, in particular to a mechanical processing cleaning wastewater treatment agent. Background technique: [0002] In the process of mechanical processing, it is necessary to use cleaning liquid to continuously clean and treat the waste materials generated in the process of mechanical processing. Therefore, a large amount of waste water from mechanical processing cleaning liquid will be generated in the process of mechanical processing. The cleaning liquid wastewater produced by processing and cleaning contains a large amount of oil, sludge, surfactants, COD, COD Cr , metal shavings, solid impurities and other pollutants. If the cleaning fluid waste water of the above-mentioned mechanical processing is directly discharged, it is very easy to cause environmental pollution. [0003] Therefore, how to realize the further recycling and reuse of the cleaning wastewater produced in the cleaning process of m...
