Abstract

The invention discloses an efficient decontamination and purification compound lime powder and a preparation method thereof. The compound lime powder is mainly prepared from the following components by weight: 45-55 parts of quicklime, 0.5-3 parts of green vitriol, 3-5 parts of alum, 0.1-3 parts of melamine, 7-13 parts of urea, and 35-45 parts of water. The efficient decontamination and purification compound lime powder provided by the invention has the characteristics of wide raw material sources, low cost, good sewage treatment effect, easy storage and exemption from damp. Green vitriol andalum are compounded into lime powder and organically combined with suspended matters in water simultaneously, can accelerate precipitation, can achieve remarkable effect on water purification and industrial wastewater treatment, and at the same time has bactericidal effect. Melamine and urea are also added into the compound lime powder, and can effectively prevent the compound lime powder from wetting and agglomeration. The added melamine has a small dosage, and does not produce secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a compound lime powder with high-efficiency decontamination and purification. Background technique [0002] In industrial acid water treatment, lime is the most commonly used neutralizing agent, which has the advantages of low cost, beneficial to sludge flocculation and sedimentation, and easy use during use. [0003] At present, the lime sold in the market is single-component quicklime or slaked lime. Therefore, in addition to adding lime, other sewage treatment agents will be added when treating sewage. The process steps are many, the operation is tedious and repetitive, and more places are needed Store different types of treatments. Contents of the invention [0004] The object of the present invention is to provide a composite lime powder capable of comprehensively treating sewage. [0005] In order to achieve the above object, the present invention a...
