Abstract
The invention provides a treating method for wastewater from vitamin B2 production. The method comprises steps of: (1) feeding the wastewater of the vitamin B2 production into a Fe/C tank, destroying the stable charge property on the surface of particles by utilization of Fe/C internal electrolysis, and forming certain Fe(OH)3 floc; (2) piping the wastewater in the step (1) into a coagulative precipitation tank by utilization of an immersible pump and removing most of SS in the water; (3) neutralizing the wastewater of the vitamin B2 production and adjusting the pH by using of caustic soda liquid; (4) replenishing the nutrient elements N and P to concentrations that are needed for microbial growth; (5) piping the wastewater in the step (4) into a hydrolytic acidification-anaerobic-aerobic biological treatment system by utilization of an immersible pump and performing biochemical treatment; (6) subjecting discharged biochemical water in the step (5) to ozone oxidation, adding a filling material into an ozone oxidation tank and controlling the gas production rate of an ozone generator; and (7) feeding the ozone-oxidized discharged water into TBF and performing secondary biochemical treatment. The discharged water meets the sewerage system incorporating standard that the COD is not less than 500 mg/L.
Description
Technical field
The present invention relates to a kind of method of wastewater treatment, especially a kind for the treatment of process of Lin Suanna Vitamin B2 Sodium Phosphate factory effluent.
Background technology
Lin Suanna Vitamin B2 Sodium Phosphate, its main effectiveness promotes the regeneration of growth and cell; Impel the normal growth of skin, nail, hair; Help to eliminate in oral cavity, the inflammation of lip, tongue; Promote eyesight, alleviate the fatigue of eyes; Help the metabolism of carbohydrate, fat, protein with other matter interaction.Use in a large number in process of production various chemical feedstockss, reactions steps is more, and raw material availability is low, and the intermediate product of most of raw material and generation is with discharge of wastewater.VITAMIN factory effluent water quality is as follows:
| Sequence number | | Water quality | |
| 1 | COD | ≤90000mg/ |
|
| 2 | BOD 5 | ≤32000mg/ |
|
| 3 | SS | ≤105920 | |
| 4 | S0 4 2- | ≤3938 | |
| 5 | NH 4-N | ≤1222mg/ |
|
| 6 | pH | 4.5-6.5 |
This concentration of organic wastewater is high, suspended substance is more and sticky, biodegradability is poor, intractability is quite large.
Summary of the invention
The invention provides the treatment process of the Lin Suanna Vitamin B2 Sodium Phosphate factory effluent that a kind for the treatment of effect is good.
The treatment process that realizes a kind of Lin Suanna Vitamin B2 Sodium Phosphate factory effluent of the object of the invention, comprises the steps:
(1) get Lin Suanna Vitamin B2 Sodium Phosphate factory effluent and enter Fe/C pond, utilize the stable electric charge of Fe/C internal electrolyte destruction particle surface, and form certain Fe (OH) 3 flcos;
(2) with submersible pump by step 1 waste water pump people coagulative precipitation tank, remove most of SS in water;
(3) get the neutralization of Lin Suanna Vitamin B2 Sodium Phosphate factory effluent, with liquid caustic soda, regulate pH;
(4) supplement the content of the necessary nutritive element N of microorganism growth, P;
(5) with submersible pump, step 4 waste water is pumped into acidication-anaerobic-aerobic biological treatment system, carry out biochemical treatment;
(6) bio-chemical effluent of step 5 is carried out to ozone oxidation, in ozone oxidation pond, add filler, control the gas production rate of ozonizer;
(7) ozone oxidation water outlet enters TBF and carries out secondary biochemical treatment, and water outlet reaches the pipe standards of receiving of COD≤500mg/L.
The beneficial effect of the treatment process of a kind of Lin Suanna Vitamin B2 Sodium Phosphate factory effluent of the present invention is as follows:
The treatment process of a kind of Lin Suanna Vitamin B2 Sodium Phosphate factory effluent of the present invention, first utilize microbiological deterioration, remove most biodegradable organics in waste water, can reduce like this consumption of ozone in follow-up ozone oxidation process, reduce processing cost, and in ozone oxidation pond, add filler, on the one hand, improve ozone and waste water duration of contact; On the other hand, utilize micro-metals (Mn2+ in filler, Co2+ etc.) katalysis improves ozone oxidation efficiency, simultaneously, singularity due to waste water, waste water, after ozone oxidation, can be separated out white precipitate material, removes the concentration that this part white precipitate substance is effectively removed waste water COD.By filler, increase duration of contact and katalysis raising ozone utilization rate; By micro-flocculation, remove residual COD in most bio-chemical effluents, can reduce as much as possible ozone dosage, reach the effect of energy-saving and emission-reduction.
