Embodiment Construction

[0021] The foam ceramic filter material uses open (type) foam ceramic as the carrier, and the shape of the foam ceramic can be made arbitrarily according to the needs. There are a lot of pores inside the foam ceramic, and the pore diameter of the pores is less than 2mm. The pores inside the foam ceramic body are filled with MgO, Mg( Oh) 2 or MgO and Mg(OH) 2 mixture.

[0022] The preparation method of above-mentioned ceramic foam filter material is as follows:

[0023] 1) Prepare the binder aqueous solution, dissolve the binder with a mass ratio of 0.1%-5% in water, and obtain the binder aqueous solution after fully dissolving, two kinds of binders can be used, one is inorganic binder Agents, such as sodium silicate, etc., and the other is organic binders, such as sodium carboxymethyl cellulose, polyvinyl alcohol, starch, etc., the binder can choose one of them, or multiple of them;

[0024] 2) Add MgO and / or Mg(OH) to the binder aqueous solution 2 Powder made into suspens...

Abstract

The invention discloses a foamed ceramic filter material which comprises an open foamed ceramic body, wherein pores inside the open foamed ceramic body are filled with MgO and / or Mg(OH)2. The foamed ceramic filter material has the advantages that new foamed ceramic is high in adsorption capacity and high in filter precision, and the pores inside the foamed ceramic are filled with a mixture of MgO and / or Mg(OH)2, so that the new foamed ceramic is strong in adsorption function; particularly, MgO generated by heating Mg(OH)2 is a nano-level MgO particle with extremely high activity, so that the foamed ceramic is stronger in adsorption function; meanwhile, MgO is still a good phosphorous remover in water, so that the new foamed ceramic has a function of clearing away orthophosphate in sewage.

Description

technical field [0001] The invention relates to the field of filter materials. Background technique [0002] At present, the open (type) foam ceramics are mainly used in sewage treatment, which utilizes the filtering effect of the pores of the foam ceramics, and the foam ceramics are used as the carrier of the adsorption filter material, but the adsorption capacity is affected by the size of the pores of the foam ceramics, and the adsorption capacity is general. Contents of the invention [0003] The technical problem to be solved by the invention is to realize a new foam ceramic structure and preparation method for optimizing the adsorption capacity of open (type) foam ceramics. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a ceramic foam filter material, comprising an open ceramic foam body, the pores inside the open ceramic foam body are filled with MgO and / or Mg(OH) 2 . [0005] The diameter of the pores is...
