Abstract
The present invention relates to a water treatment filtration material and a preparation method thereof, specifically to a lightweight water treatment filtration material for removing heavy metal pollution, and a preparation method thereof. According to the present invention, a lightweight type base material enters a reaction device; a formula solution 1 is adopted to soak the base material particles in an immerse manner; the soaked particles are taken out from the tank, and enter a refinement sand washing tank to carry out flushing hydraulic sorting; then obtained material enters an oven to carry out baking, the dried material enters a two time film overlying treatment reaction device to carry out a treatment, and a formula solution 2 is adopted to soak the semi-finished product in an immerse manner; the obtained semi-finished product is taken out from the tank, and enters the sand washing tank to carry out flushing hydraulic sorting; and the obtained material enters an air drying room, and then enters a storehouse after air drying to be the product. With the present invention, based on use of the new film compounding technology, micro-pores of the new base material is compounded with the film having a heavy metal removing ability so as to improve the heavy metal removing ability of the new filtration material.
Description
Technical field
The present invention relates to water treatment filter material and preparation method thereof, be specially lightweight water treatment filter material of a kind of removal heavy metal pollution and preparation method thereof, the characteristic of light filter material is arranged, the new material of powerful removal heavy metal pollution capacity is arranged again.
Background technology
The characteristics of China's rural drinking water source are substantially to be underground water, the heavier problem of the former water heavy metal pollution of ubiquity; It is maximum that this wherein pollutes proportion with ferrimanganic again.This class water source must through after effectively processing, just can reach national drinking water standard.
Because there is special problem in the restriction of condition on the rural potable water treatment technology, mainly contain: 1, light-duty filtrate can not pollute by removal heavy metal.2: existing removing heavy metals filtrate is larger owing to unit weight, the problem that removing heavy metals efficient is lower.This class filtrate can not obtain enough pressure in the low situation of water source head pressure, make filter not possess the backwash condition; And because removing heavy metals efficient is lower, causing water yield little, the equipment of making is larger, has increased the cost of each side.
If possible, can solve by the unit weight that reduces the core filtrate, the ability that improves the filtrate removing heavy metals; Namely seek the approaching material of a kind of unit weight and water body unit weight and be used as its core base-material, improve the production technology of film, the raising film solves the adsorption capacity of heavy metal.So just can make our water purifier overcome above-mentioned technological difficulties adaptation water source, rural area service condition, make the new water purifier operation more simple and convenient.Therefore the research and development of novel light removing heavy metals filtrate are key issues anxious to be resolved in the drinking water purification technologies in rural areas.The solution of this key technology will make water treatment facilities more satisfy the requirement of rural residents, improve cleandrinking water at the coverage rate in rural area, make new step on the rural potable water health level.
Summary of the invention
The present invention is directed to above-mentioned technical problem, lightweight water treatment filter material of a kind of removal heavy metal pollution and preparation method thereof is provided, purpose is to use the lightweight base-material to be raw material, and its key request is that unit weight and the water of new basal granule is near, and namely unit weight is 1.0g/cm
3About; Utilize simultaneously basal granule to have more micropore, use new film complex technique, also compound film with removing heavy metals ability in the micropore of new base-material improves the ability of new filtrate removal heavy metal.
Concrete technical scheme of the present invention is as follows:
Lightweight water treatment filter material that a kind of removal heavy metal pollutes and preparation method thereof, its method characteristic is: the light weight type base-material enters reaction unit, adopt formula solution 1, submerged soaks basal granule, the rear pond of rising enters refining washed-out sand pond, wash the waterpower sorting, then entering baking box toasts, enter the secondary film after the oven dry and be laminated with the processing reaction device and process, adopt formula solution 2, submerged soaks semi-finished product, play the pond after a few hours, again enter the washed-out sand pond and wash the waterpower sorting, then enter air-dry room, air-dryly laggardly enter storehouse and become product.
Lightweight water treatment filter material that described a kind of removal heavy metal pollutes and preparation method thereof, it is characterized in that described its formula solution 1 is: 100 kilograms in clear water, 0.1 kilogram in potassium permanganate, ammonia (0.1 kilogram of net content), manganese chloride 10 grams, silver nitrate (2%) 5ml.
Lightweight water treatment filter material that described a kind of removal heavy metal pollutes and preparation method thereof, it is characterized in that described its formula solution 2 is: 100 kilograms in clear water, 0.5 kilogram in potassium permanganate, ammonia (0.5 kilogram of net content), manganese chloride 20 grams, silver nitrate (2%) 10ml.
Technical characterstic has two: 1, select the suitable basal granule of unit weight, make new material unit weight become suitable level; 2, improvement is laminated with the membrane technology level, makes filtrate with better function, more is fit to the requirement that rural potable water is processed.
Innovative point: 1, the filtrate basal granule uses the novel light base-material, and 2, new membrane technology and the production technology of being laminated with.

Accompanying drawing is the flow chart of preparation method among the present invention.
The specific embodiment
The invention will be further described below in conjunction with the specific embodiment and Figure of description.
Lightweight water treatment filter material that a kind of removal heavy metal pollutes and preparation method thereof, its method characteristic is: the light weight type base-material enters reaction unit, adopt its formula solution 1 of formula solution 1(to be: 100 kilograms in clear water, 0.1 kilogram in potassium permanganate, ammonia (0.1 kilogram of net content), manganese chloride 10 grams, silver nitrate (2%) 5ml), submerged soaks basal granule, plays afterwards the pond and enters refining washed-out sand pond, washes the waterpower sorting, then entering baking box toasts, enter the secondary film after the oven dry and be laminated with the processing reaction device and process, adopt 100 kilograms in formula solution 2(clear water, 0.5 kilogram in potassium permanganate, ammonia (0.5 kilogram of net content), manganese chloride 20 grams, silver nitrate (2%) 10m), submerged soaks semi-finished product, play the pond after a few hours, again enter the washed-out sand pond and wash the waterpower sorting, then enter air-dry room, air-dryly laggardly enter storehouse and become product.
