The pharmaceutical wastewater treatment device disclosed by the utility model is high in treatment efficiency, and chemical oxygen demand (COD) removal effect in deep treatment of farm chemical wastewater and ibuprofen production wastewater is greater than 80%; the aeration system, which adopts a stainless steel perforated aerator pipe, solves the problem of changing the ceramic aeration disc which is easily damaged, saves investment, and is simple to maintain, and the service life can reach 20 years; a few of trace elements such as copper and the like in the filling material are in a synergistic effect with the ozone, so that the oxidizing effect of the ozone is improved; the ozone can bring forth a micro-flocculation effect when oxidizing organic matters, and a coagulating sedimentation process can be added in later period to remove a few of inorganic matters and a great amount of nondegradable organic matters.
Description
Technical field
The utility model relates to a kind of wastewater treatment equipment, especially a kind of pharmaceutical wastewater treatment unit.
Background technology
Ozonation technology is used for engineering of water treatment on a large scale, and the performance of its performance is limit by the water-soluble dosing method of ozone.Ozone dosing method commonly used has aeration type (directly aeration or oxidation are tower), Venturi ejector type, the negative suction of vortex or HICHINE pump mixing style etc. several, more than its water-soluble efficient can improve successively, HICHINE pump formula efficient can reach more than 95%.The main applicable engineering of above-mentioned technique is listed below:
(1) aeration type: tap water, aquaculture water, production cycle water, sanitary sewage, trade effluent etc.;
(2) Venturi jetting type: secondary water-supply, pure water, mineral water, aquaculture water cooling, swimming-pool water etc.;
(3) negative suction: little water body is used;
(4) gas-liquid mixing pump formula: little water body is used or ozone-containing sterilizing water is used;
Usually adopt the aeration type contact-oxidation pool in large-scale water treatment, the bottom is adopted ceramic aeration plate usually, adopts the shortcoming of above-mentioned reactor to mainly contain 1. as reaching efficient mass transfer, and effective pond of contact tank is deeply larger; 2. ceramic aeration plate micropore stops up easily, and is more outstanding when particularly having iron, manganese in intermittent operation and water; Produce easily channel when 3. bubble rises, gas-to-liquid contact is caused disadvantageous effect; 4. ceramic aeration plate is once changed completely every several years needs.
The utility model content
The utility model provides that a kind for the treatment of effect is good, less investment, the simple pharmaceutical wastewater treatment unit of maintenance.
Realize a kind of pharmaceutical wastewater treatment unit of the utility model purpose, comprise oxidation pond, be provided with the perforated wall for water distribution in the described oxidation pond, oxidation pond is divided into inlet segment and water exit end, described water exit end is provided with filler, and the bottom of described filler is provided with ozonation aerated pipe.
The beneficial effect of a kind of pharmaceutical wastewater treatment unit of the present utility model is as follows:
A kind of pharmaceutical wastewater treatment unit of the present utility model, processing efficiency is high, in the advanced treatment of agricultural chemicals waste water and Ibuprofen BP/EP factory effluent, the removal effect of COD is surpassed 80%; Aerating system adopts the stainless steel boring aeration pipe, has solved the perishable difficult problem that need to change of ceramic aeration plate, saves investment, safeguards that simply can reach 20 years work-ing life; A small amount of trace element in the filler, such as copper etc., and ozone forms synergy, can improve the oxidation effectiveness of ozone; Ozone can also produce the effect of little flocculation in oxidation of organic compounds, the later stage can be added coagulation-settlement process and be removed small part inorganics and a large amount of hardly degraded organic substance.
Description of drawings
Fig. 1 is the structural representation of a kind of pharmaceutical wastewater treatment unit of the present utility model.
Embodiment
As shown in Figure 1, a kind of pharmaceutical wastewater treatment unit of the present utility model comprises oxidation pond 1, be provided with the perforated wall 2 for water distribution in the described oxidation pond 1, oxidation pond 1 is divided into inlet segment and water exit end, and described water exit end is provided with filler 4, and the bottom of described filler 4 is provided with ozonation aerated pipe 3.
The principle of work of a kind of pharmaceutical wastewater treatment unit of the present utility model is as follows:
Oxidation pond 1 fluidised form adopts pulling flow type, and waste water enters after the inlet segment, through perforated wall 2 water distributions, pass through uniformly filler 4, the layer by layer cutting of ozonation aerated pipe 3 aerations of bottom, bubble process filler 4 in uphill process, bubble diminishes gradually, can improve ozone utilization rate.A small amount of trace element in the filler 4 simultaneously, such as copper etc., and ozone forms synergy, can improve the oxidation effectiveness of ozone.Ozone can also produce the effect of little flocculation in oxidation of organic compounds, the later stage can be added coagulation-settlement process and be removed small part inorganics and a large amount of hardly degraded organic substance.
The advantage of a kind of pharmaceutical wastewater treatment unit of the present utility model is as follows:
(1) stable and reliable operation, it is high to remove efficient, and anti-shock loading is strong, is applicable to the advanced treatment process behind the trade effluent biochemical process;
(2) aeration mode is realized easily, and construction and installation are simple and convenient;
(3) water outlet biochemical is improved, can follow-up use biochemical processing process, and the ozone automatic classifying is non-secondary pollution behind the oxygen, and make oxygen in water often be state of saturation or near state of saturation, provide prerequisite for the biological degradation in the follow-up biological vehicle treated again, also reduce extraneous air quantity to system, also just reduced the requirement to the blower fan blast volume;
(4) a small amount of trace element in the filler is such as copper etc.; Form synergy with ozone, can improve the oxidation effectiveness of ozone;
(5) ozone can also produce the effect of little flocculation in oxidation of organic compounds simultaneously, and the later stage can be added coagulation-settlement process and be removed small part inorganics and a large amount of hardly degraded organic substance.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
