Do you know the four characteristics of sewage treatment filler [iron-carbon micro-electrolysis filler]?
Sewage treatment filler [iron carbon micro-electrolysis filler] four major functions do you know?
Sewage treatment filler [iron-carbon micro-electrolysis filler] type of wastewater treatment, do you know?
Sewage treatment filler [iron-carbon micro-electrolysis filler] sewage treatment experiment do you know?
These questions are answered by the technical department of Weifang Puyinworun Environmental Protection Technology Co., Ltd.
1. Four characteristics of iron-carbon micro-electrolysis filler:
(1) Large specific surface area (2) Airflow can be evenly distributed in the filler layer. (3) Liquid has good uniform distribution on the surface of the filler. (4) Filler has a large void ratio.
2, iron and carbon micro-electrolysis filler four major functions (1) reduce sewage cod
(2) Improve the biodegradability of sewage (3) Remove the chromaticity (4) Break the chain
3. Types of wastewater treatment of iron-carbon micro-electrolytic fillers (1). Dyestuffs, chemical, pharmaceutical wastewater, coking, petroleum wastewater
------The BOD/COD value of the above wastewater treatment water is greatly improved.
(2). Printing and dyeing wastewater, leather wastewater, papermaking wastewater, wood processing wastewater
------ It has a good application for decolorization, and it can effectively remove COD and ammonia nitrogen.
(3). Electroplating wastewater, printing wastewater, mining wastewater, other wastewater containing heavy metals
------ Heavy metals can be removed from the above wastewater.
(4). Organic phosphorus agricultural wastewater, organic chlorine agricultural wastewater
------ greatly improve the biodegradability of the above wastewater, and can remove phosphorus, in addition to sulfides.
4. Static micro-electrolysis test of iron-carbon micro-electrolytic filler wastewater treatment experiment:
Required equipment: 1L beaker, aeration device, micro-electrolytic filler, acid, alkali, testing equipment; adjust the pH value of the wastewater to be treated to 2-4 (test separately); add about 1L of filler in a 1L beaker, An aeration head is placed at the bottom of the beaker to make an aeration device; the waste water is poured into the beaker and there is no filler, and the aerator is opened for aeration; the gas-water ratio is recommended to be controlled within 3:1 (Note: the surface of the water can be boiled) Time adjustment: The test can be carried out in several time periods of 30 minutes, 60 minutes, 90 minutes, 120 minutes, etc.; after the reaction is finished, the waste water is poured into another container with sodium hydroxide or hydroxide. The calcium is adjusted to a pH of between 8 and 9 for precipitation, and the supernatant is allowed to stand for a period of time to detect various data;
Dynamic microelectrolysis test:
The dynamic test can be used to simulate the reactor placement site for continuity test. The structure of the reactor can be designed according to the wastewater and the site conditions. The test parameters can be calculated as follows: the specific gravity of the filler is 1 ton / cubic meter, and the porosity of the microporous is calculated as 60%. Then, if the micro-electrolysis treatment time is 60 minutes, one cubic filler can treat 0.6 cubic meters of water per hour. If the test treatment is 30 minutes, the amount of water that can be treated per cubic cube of filler per hour is: 60/30*0.6=1.2 cubic water; Others can be deduced by analogy.
