Technical field

The present invention relates to the ceramic particle technology field for sewage water filtration, especially a kind of sewage water filtration ardealite haydite and Preparation method.

Background technique

Haydite, is the particle of ceramic, and external appearance characteristic is largely rounded or oval-shaped ball, and also having on a small quantity is imitative rubble etc. The particle of irregular shape；Its surface has one layer of hard shell, this layer of shell is in ceramic or enamel, and it is higher to assign haydite Intensity；Moreover, haydite has more hole, there is sufficient permeability, also, hole has preferably absorption property, More vapor can be adsorbed, so that water conservation performance of keeping humidity is stronger.For this purpose, there is researcher that haydite is used for soilless cultivation, garden The fields such as woods greening, the preparation for haydite are conceived to always the cost and haydite compression strength and low of the preparation to haydite It is studied in terms of density, but is not all obtained biggish breakthrough, so that the bulk density of haydite is maintained at 600kg/m3 or more, cylinder Compressive Strength is in 5MPa hereinafter, the quality for affecting ceramic product and ceramic product of high degree are answered in terms of sewage treatment Period.

Ardealite is the solid waste of phosphorus chemical industry output, has many characteristics, such as lightweight, but since ardealite is plastic Property it is very poor, cause ardealite less in the application amount of every field, if any researcher by ardealite be applied to haydite preparation field, Ardealite can not carried out to the preparation of haydite directly as primary raw material, but as a small amount of addition in the main original of haydite In material, and pass through granulating and forming, the modes such as maintenance or sintering obtain haydite.As it can be seen that in the prior art prepared by haydite Cheng Zhong, it is difficult to largely be produced using ardealite as raw material, so that the heap of a large amount of solid waste generated for phosphorous chemical industry Storage is difficult to be eased.

In consideration of it, this researcher is in the base for considering the comprehensive performances such as haydite preparation cost and haydite density, compression strength On plinth, the primary raw material that ardealite is prepared as haydite, and add other auxiliary materials so that the ceramic product performance of preparation compared with It is good, it can be used in reducing the content of harmful components in sewage to the dirty water decontamination handles, to mention for the production of the haydite of sewage treatment For a kind of new approaches.

Summary of the invention

In order to solve the above technical problems existing in the prior art, it is good and pollution-free to provide a kind of filter effect by the present invention Ardealite haydite preparation method.

It is achieved particular by following technical scheme:

A kind of filter effect is good and free of contamination ardealite haydite, mainly includes ardealite and clay,

Ardealite Contents of Main Components are as follows: 50-80 parts of calcium sulfate, 2-8 parts of magnesia, 0-15 parts of silica 1, three oxidations Two 1-5 parts of aluminium, 2-6 parts of three oxygen, two iron.

Clay Contents of Main Components are as follows: 30-50 parts of silica, 10-20 parts of di-iron trioxide, aluminum oxide 5-10 Part, 3-10 parts of di-iron trioxide, 1-6 parts of calcium oxide, 1-7 parts of sodium oxide molybdena, 2-6 parts of potassium oxide.

Further, a kind of filter effect is good and free of contamination ardealite haydite preparation method, comprising the following steps:

(1) by ardealite, drying to constant weight, and grind into powder, sieves with 100 mesh sieve, and obtains phosphogypsum powder；

(2) it is that 1:0.3-0.6 is mixed, and is ground according to mass ratio with sodium tripolyphosphate by clay, sieves with 100 mesh sieve, obtain viscous Native powder；

It (3) is that 1:1.1 is mixed, and adds ferrous sulfide quality 2.5- according to mass ratio with aluminum oxide by ferrous sulfide 6 times of shale, grinding, sieves with 100 mesh sieve, obtains shale powder；

(4) phosphogypsum powder, clay powder, shale powder are mixed according to mass ratio for 7-10:0.3-0.9:1-4, mixes thoroughly, adds Water, be sent into pelletizer granulating and forming, fire to get.

Further, the step (2), clay are that 1:0.4 is mixed according to mass ratio with sodium tripolyphosphate, the step Suddenly (3), shale additive amount are 7 times of ferrous sulfide quality, the step (4), phosphogypsum powder, clay powder, shale powder according to Mass ratio is 8:0.6:2.3 mixing

Further, described plus water, water material mass ratio are 0.1~0.9.The molding, grain diameter 4-20mm. The firing is first to be preheated to 100 DEG C, then be warming up to 250 DEG C, constant temperature 4min in 4min, then be warming up to 1000 in 25min DEG C, constant temperature 0.5-1h is cooled to room temperature in 4h.

Further, the sewage water filtration of preparation ardealite haydite.Bulk density is 356~506kg/m3, cylinder pressure Intensity is 11.8~15.4MPa, and 1h water absorption rate is 4~9%, and hydrochloric acid soluble rate is 0.8%.

Compared with prior art, the technical effect of the invention is embodied in:

By ardealite is prepared into phosphogypsum powder, clay is prepared into clay powder by modification, shale and vulcanization is sub- After iron, aluminum oxide interaction, it is prepared into shale powder, and phosphogypsum powder, clay powder, shale powder are reasonably matched Design, so that the utilization of ardealite is more, clay, the utilization of shale are lower, reduce the consumption to natural resources, realize Effective use to phosphorous chemical industry waste, reduces costs.

Processing is modified using sodium tripolyphosphate in conjunction with by clay, and combines shale using ferrous sulfide, three oxidations two Aluminium is handled, so that the stable structure of haydite, and in sintering procedure, promote the formation of hole, improves the hole of haydite Rate enhances adsorption capacity and exchange capacity, realizes the improvement function to water quality, improves the compression strength of haydite, drops low bulk density.

It handles by forming and sintering, in conjunction with the selection of material composition, so that form a large amount of calcium base inorganic salts, improves pair Phosphatic removal ability in water；Moreover, the rational proportion by clay, shale, ardealite designs, so that haydite compression strength It is higher, and bulk density is lower, can bear the load that sewage washes away for a long time, extends the period of purified water, reduces at sewage Manage cost.
