Embodiment 1

[0019] 100 kg of palygorskite (attapulgite) clay is dried at 105°C by a common dryer, then ground by a Raymond mill, passed through a 200-mesh sieve, and 4% hydrochloric acid is added to the under-sieve to submerge the clay. After stirring for 3 hours with an ordinary mixer, filter the solution with a plate and frame filter press or a centrifugal filter to filter or filter out the clay. Put the acid-washed clay into a dryer, adjust the temperature to 105°C, and dry it into blocks. After drying, it will be ground to 200 mesh by a Raymond mill, and it will be used for later use.

Embodiment 2

[0021] Take 5 kg of liquid organic resin and 100 kg of clay and stir them thoroughly for about 3 hours to allow the two phases to mix evenly. (A certain amount of absolute ethanol can be added if necessary) Put the mixed clay into a crucible with a cover, cover and seal it, put it into a muffle furnace, heat it to 360°C, and keep it warm for 30 minutes to get carbonized soil.

Abstract

The invention discloses a preparation method of palygorskite. According to the preparation method, organic resin and palygorskite clay are mixed according to a certain ratio, the mixture is fully stirred to evenly mix two phases, then the clay is grinded and dried to obtain the palygorskite; the palygorskite (carbonized soil) can be used to treat wastewater containing heavy metal ions, and the once elimination rate can reach 99.5%.

Description

technical field [0001] The present invention relates to a kind of assembly and preparation method of palygorskite, more specifically a kind of assembly of palygorskite (attapulgite) clay and its preparation (carbonization) method. Background technique [0002] Palygorskite clay is widely used in the industrial field, mainly used as adsorbent, water treatment and other fields, but the application process is not satisfactory, especially in wastewater containing heavy metal ions (such as hexavalent chromium wastewater). The ideal effect of pollution control. Contents of the invention [0003] The purpose of the present invention is for the treatment of chromium-containing (hexavalent) waste water, and the palygorskite (attapulgite) that adopts is after being prepared (carbonized), and is used in the treatment of industrial waste water. The industrial wastewater that cannot be fully adsorbed, removed impurities and harmful substances is treated to meet the discharge standard,...
