Brief description of the drawings
Fig. 1 is the flow diagram of the present invention；
Embodiment
The invention will now be described in further detail with reference to the accompanying drawings, but is not the limit to the scope of the present invention System.
As shown in Figure 1, the present invention by steroid pharmacy waste water from workshop water outlet categorised collection be three parts：High solvent gives up Water, high slat-containing wastewater, low concentration wastewater.Three strands of classification of waste are collected, dual treatment.
Low concentration wastewater is directly entered low concentration wastewater regulating reservoir and carries out water quality and quantity adjusting,
High solvent waste water enters high-concentration waste water regulating reservoir progress water quality and quantity tune after carrying out carrying out precipitation treatment using revolving bed Section, high slat-containing wastewater enter the progress water quality and quantity adjusting of high-concentration waste water regulating reservoir after carrying out desalting processing using MVR.
High-concentration waste water regulating reservoir water outlet is pumped to air flotation turbo by regulating reservoir, pretreatment early period has not been removed molten Agent and grease continue to remove, it is ensured that the stable operation of aftertreatment systems.
Waste water is directly entered Fe/C reaction tanks through air supporting, and pH is adjusted to acidity, using light electrolysis principle, difficult biochemical drop of degrading Microorganism is solved, while generates Fe2+、Fe3+, as follow-up Fenton catalysts, reduce follow-up Fenton reactions dosage.
Iron-carbon micro-electrolysis be flocculation, absorption, bridge formation, volume sweep, be coprecipitated, electro-deposition, a variety of effect synthesis such as electrochemical reduction Effect as a result, can effectively low removal pollutant, improve the biodegradability of waste water.
Iron-carbon micro-electrolysis be based on the cell reaction in electrochemistry, when iron and carbon-impregnated are entered in electrolyte solution, due to There are the difference in Electrode Potential of 1.2V between Fe and C, thus countless light electrolysis systems can be formed, one is formed in its action space The Fe of a large amount of nascent states produced in electric field, newly generated iron surface and reaction2+There is high chemism with atom H, can change The structure and characteristic of many organic matters in waste water, make organic matter that chain rupture, open loop occur；The field effect of micro cell surrounding them It can make the charged ion in solution and the attached collection of colloid and deposit on the electrode and remove；In addition the Fe in reacting2+、Fe3+And its water Compound has strong adsorption-flocculation activity, can further improve treatment effect.
Waste water after Fe/C reactions is acidity, reacts pH conditions beneficial to Fenton.The modified form Fenton that this programme uses Oxidizing process, cardinal principle are additional H2O2Oxidant and Fe2+Catalyst, i.e. Fenton medicaments, both meetings under appropriate pH Reaction produces hydroxyl free radical (OH), and the organic matter in the high oxidative capacity and waste water of hydroxyl free radical reacts, decomposable asymmetric choice net Oxidation of organic compounds, and then reduce the COD of bio-refractory in waste water.The Fe in Fenton reaction tanks2+With H2O2Reaction can be formed Fe3+, it is necessary to adjusted in pH in pond and adjust pH to neutrality to form Fe (OH)3, and be gathered into flocculation basin by polymer Bulky grain, removes in chemical precipitation pond.Due to Fe3+Inherently extraordinary coagulant, thus in this process except By Fe (OH)3Except separating, while also there is extraordinary remove function to colourity, SS and colloid.More than react after Complete the mud-water separation process of materialized mud and waste water in physico-chemical precipitation pond.
Waste water after materialized pretreatment carries out water quality water before biochemical treatment system is entered in water quality and quantity balancing tank The adjusting of amount is balanced, it is ensured that keeps stablizing into biochemical treatment system water quality and quantity.
Waste water is pumped to anaerobic fixed film reactor by water quality and quantity balancing tank, improves wastewater biodegradability, reduces wastewater toxicity.Detest Oxygen hydrolysis set filler in pond, the microorganism of time length is largely adhered to and dwell life on filler, under these microbial actions, It can make to be difficult to biodegradable baroque organic matter in sewage to be converted into organic matter simple in structure, be easier to by microorganism profit With and absorb, improve Biodegradability of Wastewater, beneficial to follow-up Aerobic biological process.
Aerobic system uses A/O techniques, and is divided to two sections to realize de- C, de- N and phosphorus removal functional.This case uses two sections of A/O processing System, underload and high load capacity microorganism are separated, and each play its maximum efficiency, one section based on de- C, two sections using de- N as It is main.Microorganism lives in the alternate environment of anaerobic-aerobic and is screened in A/O systems.A sections of main function is to micro- life Thing strain is screened and optimized, and microorganism is simply absorbed and adsorbed to the organic matter in waste water in this section, and to organic The decomposition of thing is in O sections of completions.At A sections, the residence time of sewage is very short, since majority of organic pollutants is taken off at A sections Phosphorus microorganism adsorption enters in vivo, is then aoxidized and decomposed in O sections.At the same time O sections under the action of nitrobacteria by waste water Ammonia nitrogen and by organic nitrogen ammonification into ammonia nitrogen, acted on by biological nitration, be converted into nitrate.In anoxic section, denitrifying bacteria By the part nitrate that secondary settling tank sludge reflux is brought into by biological denitrification, change into nitrogen and escape into air.
Anaerobic fixed film reactor water outlet enters one section of A/O, utilizes aerobic and facultative microbe (the digestion bacterium for having adapted to hc effluent With denitrifying bacterium etc.) de- C is carried out, N and dephosphorization processing are taken off, wherein one section of A/O is based on de- C.After one section of A/O processing, sink in Mud-water separation is completed in pond, and highly concentrated sludge reflux to A ponds ensures A/O system activity sludge concentrations, at high load capacity aerobic microbiological Reason system is separated with two sections of A/O underload aerobic microbiological processing systems below；
One section of A/O water outlet is precipitated into medium sediment pool.
Medium sediment pool water outlet enters two sections of A/O, utilizes aerobic and facultative microbe (the digestion bacterium and anti-for having adapted to low density wastewater Nitrifier) carry out further taking off C, de- N and except P processing, wherein based on de- N, it is ensured that TN is up to standard；
Two sections of A/O water outlets enter sedimentation in secondary sedimentation tank.
Steroid pharmacy waste water feature be containing hormonal substance, it is necessary to carry out inactivation could discharge, after biochemical treatment, adopt Inactivated with soda acid and advanced oxidation mode, then qualified discharge after precipitation.
(medium sediment pool sludge, secondary settling tank sludge and end are heavy for materialized mud (sludge in materialized mud pond) and biochemical excess sludge Pond sludge) enter sludge treating system progress thickening processing.
