Embodiment 1

[0071] A composite filter element 8 for emergency water supply, comprising multiple layers of hollow cylindrical filter layers tightly connected in sequence, from the outside to the inside are ceramic layer 8.1, composite adsorption layer 8.2, protective layer 8.3 and activated carbon layer 8.4, according to the complex water quality conditions outdoors For the types of pollutants contained, a purification system covering the whole range is designed in a targeted manner, which can remove heavy metals, organic matter, bacteria, viruses and other pollutants in the water, and treat water sources of five or more categories into drinking water.

[0072] The purification effect achieved by the four-layer filter material completely covers the types of pollutants in outdoor water sources, and the treated water can be used in emergency rescue situations. In particular, it should be emphasized that the application scenario of the present invention is emergency rescue water supply. The pr...

Embodiment 2

[0090] The composite adsorption layer passes through the following steps:

[0091] Step 1, mixing one or more of zeolite powder, bentonite, kaolin, graphene, and alumina to obtain a mixture;

[0092] Step 2, fully grind the above mixture, and control the particle size of the mixed powder obtained by grinding to be higher than 200 mesh, preferably 300-500 mesh;

[0093] Step 3, performing nano-iron modification on the grinding mixture powder obtained in step 2, forming nano-zero-valent iron particles inside the micropores of the mixed powder particles, and obtaining a modified mixed powder;

[0094] Step 4, drying the modified mixed powder obtained in step 3 at 300°C to 500°C for 5h to 10h;

[0095]Step 5, adding an adhesive with a mesh number higher than 200 mesh to the dry modified mixed powder obtained in step 4, mixing evenly,

[0096] Step 6, extruding the mixture obtained in step 5, the high-density extrusion process has 4 stages:

[0097] The first stage: under the co...

Embodiment 3

[0139] An emergency water supply filter 1, comprising a housing 2 and a composite filter element as described in Embodiment 1 or Embodiment 2 fixed in the housing 2, the center of the composite filter element forms a central cavity, and the housing A water inlet 6 is formed on the side wall of the housing, and a water outlet 7 is formed at the bottom of the housing. The inner bottom of the housing is provided with a tray 3 for fixing the bottom of the composite filter element, and the outer edge of the tray 3 is sealed and fixed on the On the inner wall of the housing, a water collection hole corresponding to the central cavity is formed in the center of the tray 3 , and the top of the housing is fixed with a briquetting block 5 that seals and compresses the top of the composite filter element.

[0140] The briquetting block 5 presses down the top of the composite filter element and seals the top of the cavity. The tray 3 is used to fix and seal the bottom of the composite filt...

Abstract

The invention discloses a composite filter element for emergency water supply, a preparation method of the composite filter element, a filter and a filtering method of the filter, the composite filter element comprises a plurality of hollow cylindrical filter layers which are tightly connected in sequence, each hollow cylindrical filter layer comprises a ceramic layer, a composite adsorption layer, a protective layer and an activated carbon layer from outside to inside in sequence, and a cavity is formed in the center of the activated carbon layer. The composite adsorption layer is formed by extruding a porous material and a binder, the protective layer is made of KDF and ATS adsorption resin, and the porous material is a mixture of one or more of zeolite powder, bentonite, kaolin, graphene and aluminum oxide. The composite filter element is good in filtering effect and especially suitable for emergency water supply.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a composite filter element for emergency water supply, a preparation method and an application. Background technique [0002] China is one of the countries that suffer most from natural disasters in the world. When a disaster occurs, most of the cases will cause damage to the drinking water supply system and deterioration of the quality of drinking water, including various bacteria, microorganisms, organic matter, and heavy metals in the water. etc. When these pollutions exceed the capacity of the human body, water-borne diseases will occur, and in severe cases, it will threaten the lives of the people and social stability. [0003] The commonly used emergency relief water supply equipment at this stage includes water trucks, water purification equipment, and air-dropped bottled water, etc. However, it is difficult to implement in the event of power outages, road damage, ...
