Remove；
Atomization process pond, for the sewage after the processing of FC processing ponds to be carried out into oxidation processes, passes through hydrogen peroxide and catalyst
Iron ion Fe2+ with two positive charges constitutes oxidation system, hydrogen peroxide is discharged hydroxyl free radical under the reaction of catalyst,
It is further to remove COD and colourity so as to trigger radical chain reaction；Sent out by instantaneous high-temperature and duration of response molecular structure
It is raw to change, by macromolecular on behalf of multiple small molecules；Enter to adding calcium hydroxide, RED-OXY strong oxidizers in the sewage after oxidation
One step aoxidizes the COD and colourity in water and removes pollutant.
Wherein, also include：
Sedimentation basin, for receiving the sewage after atomization pond is aoxidized, to be precipitated, and adjusts pH value simultaneously；Addition
PAC and PAM carries out separation of solid and liquid；Then the sludge after separation of solid and liquid is transported to sludge-tank, the clear water isolated is transported to clearly
Pond.
Wherein, also including main control server, FC reactions are also referred to as Friedel-Crafts reaction (Fu Rui Deer-Kerafyrm thatch, Friedel-
Crafts).Aromatic hydrocarbon is under anhydrous AlCl3 effect, the reaction that ring hydrogen atom is replaced by alkyl or acyl group.For example benzene and
Halogenated hydrocarbons reacts under AlCl3 catalysis, and benzene ring hydrogen is replaced by alkyl, referred to as alkylated reaction.Benzene and acyl chlorides, acid anhydrides exist
AlCl3 catalysis is lower to react, and benzene ring hydrogen is replaced by acyl group, referred to as acylation reaction.
The above-mentioned technical proposal of the present invention has the beneficial effect that：Above-mentioned technical proposal proposes a kind of heating circulation power
Control method and system, it is possible to increase the control effect of heating water.Inventor is by the way that very analysis is demonstrated in detail simultaneously
The type selecting of the parts of each in whole system, with the excellent effect in theory with actually used middle explanation whole system.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of the embodiment of the present invention.
Embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
