Treatment of arsenic pollution
The arsenic-containing wastewater comes from industrially emitted trivalent arsenite, arsenate, arsenic dust and arsenic oxides. Containing wastewater treatment method are more commonly used are: lime method, Fe, Mn method, a curing method, and a method of soft manganese comprehensive recovery method. Hunan is one of the main mining of arsenic minerals produced gold extraction, gold Huangjindong using rotary kiln roasting arsenic removal and recovery of arsenic trioxide (AsO 2 O 3), but because of equipment, operation and management is not perfect, the flue gas, The smoke and dust leakage are relatively serious, so it is necessary to continue to renovate and improve. In addition to the above-mentioned method for removing arsenic from a large number of arsenic-containing gold mines that need to be developed and utilized, it is necessary to actively explore and study some new technologies for wet arsenic removal, and introduce new methods that have achieved good results abroad, and how to use Xinnuo process. Lab Seed Cleaner & Grader
The 5XZC-L laboratory
seed cleaner & grader is precision equipment for particulate material
cleaning and grading. It is suitable for separation of all seed types, as
grain, grass seeds, flower seeds, vegetable seeds, herb seeds and so on.
Working principle:
Lab seed cleaner is mainly used for all kinds of seed processing
characteristics test and research. It is also widely used for quantity
high-value seeds cleaning and size classification. The seed cleaner is air
screen structure. It has former and rear dust separating air pipes, so you can
clean the dust, light impurities and blighted seeds from good ones. Vibrating
sieve trunk is installed 3 sieve layers in the upper, middle and lower part.
First sieve layer is used to separate large impurity & large seeds. Second
sieve layer is used to separate small impurity & small seed. The rest seeds
are qualified seeds and they go to main discharge outlet. By adjusting the
frequency converter button, you can control the sieve trunk vibration and control
material running speed on sieve screen surface. There are also several air
volume adjusting handles to help you get the suitable air suction. So you can
well manage the seed cleaning effect by adjust trunk vibration frequency and
air volume. At bottom of the sieve trunk, there is an air filter. Dusty air
produced after winnowing will be discharged after filtering. This is
environmental protection design.
Feature:
Lab seed cleaner & grader is two air screens structure. The front and rear part
both has one air cleaning system. In air cleaning procedure, it removes dust,
light impurities and unfilled seeds. Vibration sieve trunk is equipped with three
sieve layers which used to separate large impurity, and small impurity. After whole
cleaning processing, qualified seeds are separated from impurity.
