Abstract
The present invention relates to filter aid and method for making and application that a kind of industrial sewage purification Separation of Solid and Liquid is used.This filter aid by following compositions by weight ratio make: flyash 80-90, porous diatomite 10-20.Method for making is after described raw material is ground into 40 orders-400 order respectively, by the weight portion ratio of prescription requirement, stirs, and mixes.This filter aid is applied in the filtration system, during particularly vacuum drum filtration, belt filter press filter.Advantage of the present invention is to use this filter aid can form the filter course of high osmosis, the filtering fine particles, thus reach the raising solid-liquid separation effect, improve the desilt amount, make stable effluent quality, industrial production aim of stable operation.
Description
Technical field
The present invention relates to filter aid and method for making and application that a kind of industrial sewage purification Separation of Solid and Liquid is used.
Background technology
Because Anshan iron and steel plant two steelmaking system transformations; the coarse granule machine of inclined-plate clarifying basin front end is removed big particle; remaining fine particles does not form filter course; cause the vacuum filter dehydration difficult; therefore the filtrate of higher concentration returns inclined-plate clarifying basin; increase the weight of the swash plate working strength, cause system's fluctuation of service.
Summary of the invention
The purpose of this invention is to provide a kind of industrial sewage purification Separation of Solid and Liquid filter aid and method for making and application, use this filter aid can form the filter course of high osmosis, the filtering fine particles, thereby reach the raising solid-liquid separation effect, improve the desilt amount, make stable effluent quality, industrial production aim of stable operation.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of industrial sewage purification Separation of Solid and Liquid filter aid, it mainly by following compositions by weight ratio make: flyash 80-90 weight portion, porous diatomite 10-20 weight portion.
Described filter aid also comprises bentonite 1-5 weight portion.
Described filter aid also comprises steel slag or scrap iron slag 1-5 weight portion.
The method for making of described a kind of industrial sewage purification Separation of Solid and Liquid filter aid, this method for making may further comprise the steps:
1) described raw material is ground into 40 orders-400 order respectively, stand-by;
2) by the weight portion ratio of prescription requirement, with above-mentioned stand-by raw material after metering, put into batch mixer and fully stir, mix, deposit in the feed bin after stirring;
3) with the product that stirs in the feed bin through after the assay was approved, go into warehouse for finished product.
This filter aid is applied in the filtration system, during particularly vacuum drum filtration, belt filter press filter.
In the above composition, because the specific area of flyash is big, high adsorption capacity has the characteristic of macromolecule polycondensation, so its easy absorption, can form filter course; Porous diatomite internal capillary is abundant, and its main effect is exactly under the prerequisite that guarantees the higher rate of filtration, removes impurity and fine suspension in the sewage, reduces the filtrate turbidity.
Compared with prior art, the invention has the beneficial effects as follows:
1) use flyash to be raw material, can strengthen adsorption capacity, mud cake is thickened, mud volume increases;
2) porous diatomite internal capillary is abundant, can effectively improve the rate of filtration, removes impurity and fine suspension in the sewage, reduces the filtrate turbidity;
3) can make the remaining fine particles of inclined-plate clarifying basin form effective filter course, make swash plate stable operation.
