4th, SEPT-HECAF1#, labyrinth 2#, intermediate pool 3#, SEPT-HECAF2#, labyrinth 3#, intermediate pool 4#, SEPT-
HECAF3#, labyrinth 4#, intermediate pool 5#
The waste water that intermediate pool 2# comes out enters SEPT-HECAF1#, and SEPT-HECAF is air supporting flocculation basin, the flocculation basin
Structure is disclosed by patent CN201521141692.8, is specifically shown in HECAF1# structures and relevant drawings in the patent, is no longer gone to live in the household of one's in-laws on getting married
State.
Water inlet of the waste water below equipment enters, when flowing through flocculating bed, occurs a series of physics with target contaminant
Chemical reaction, produces the coagulant and oxidant of one or more nascent states, passes through flocculation, adsoption catalysis oxidation Decomposition, displacement
Etc. a variety of materializations effect, the pollutant in waste water is set to remove rapidly.Simultaneously device otherwise stop aeration, make reaction more abundant.
This water technology device has efficient, quick, sludge quantity special due to integrating a variety of physics chemical actions
Less, reduced investment, floor space are small, operating cost is low, it is applied widely, the features such as a variety of inorganic and organic matter can be removed simultaneously.
Waste water can be SEPT-HECAF1#, labyrinth respectively by three sections of SEPT-HECAF, labyrinth and middle pool device
2#, intermediate pool 3#, SEPT-HECAF2#, labyrinth 3#, intermediate pool 4#, SEPT-HECAF3#, labyrinth 4#, intermediate pool 5# pass through
SEPT-HECAF waste water can produce substantial amounts of sludge and flocculate, it is necessary to set maze device by sludge settling removal system,
The blocking and damage of follow-up equipment are prevented, three sections of SEPT-HECAF modules are set, it is therefore an objective to make the oils in waste water and surface
Activating agent, organic solvent etc. is removed completely, it is ensured that the water quality subsequently intake.
5th, SEPT-EMFR2#, intermediate pool 6#, SEPT-LVER1#, intermediate pool 7#, SEPT-LVER2#, labyrinth 5#, intermediate pool
8#, SEPT-EMFR3#, intermediate pool 9#, labyrinth 6#
After three sections of SEPT-HECAF, enter SEPT-EMFR2# from the intermediate pool 5# waste water come out, continue to remove waste water
In salinity and COD, then waste water enter SEPT-LVER1# through intermediate pool 6#.
SEPT-LVER is low pressure electrocatalysis oxidation apparatus, utilizes three electrode electro Chemical technologies and catalytic oxidation technologies
Coupling, from the principle of three-diemsnional electrode, carrier is made with charcoal etc., inorganic oxide is initiator, and excitation energy, power supply are made with electric energy
For pulse direct current.Under relatively low safe dc voltage (<50V), it is anti-by a series of chemistry using the oxygen in air
Answer the H of mechanism formation nascent state2O2, further decompose produce the hydroxyl radical free radical (OH) with extremely strong oxidisability therewith.Hydroxyl
Free radical can rapid oxidation be polycyclic or heterocyclic arene class, and the small molecule for being allowed to be degraded to easily further to be decomposed by microorganism has
Machine thing, in addition by the thorough mineralising of hydroxyl radical free radical be carbon dioxide and water.
SEPT-LVER structure is disclosed by patent CN201521141692.8, is specifically shown in LVER1# in the patent and is tied
Structure and relevant drawings, are repeated no more.
SEPT-LVER devices are mainly COD, ammonia nitrogen and colourity in reduction waste water, and this technique sets two sections of SEPT-LVER to fill
Put, be SEPT-LVER1#, intermediate pool 7#, SEPT-LVER2# respectively.Add labyrinth 5# behind SEPT-LVER2#, can effectively remove
The sludge and flocculate for going this segment process section to produce.
Waste water enters SEPT-EMFR3# through intermediate pool 8#, further reduces chroma in waste water, ammonia nitrogen and salt content, most passes through afterwards
Intermediate pool 9# enters labyrinth 6#, removes after sludge settling, into last clear water reserviors.
Wastewater treatment index after this technological process is shown in Table 1.
