Abstract
The utility model provides a foodstuff-grade polyvinylidene chloride resin production waste water treatment system for controlling over standard of chloride ion and COD, which comprises a high density chloride ion waste water treatment apparatus and an integration waste water pool, and also comprises an organic matter removing apparatus at a water inlet of the high density chloride ion waste water treatment apparatus; the integration waste water pool is provided with a chloride ion detection apparatus connected with an output control pump of the high density chloride ion waste water treatment apparatus and a COD detection apparatus. The organic matter removing apparatus is added for effectively removing organic matter in monomer operation waste water, and waste water after removal treatment enters into the high density chloride ion waste water treatment system. A on-line detection apparatus can carry out on-line monitoring of chloride ion concentration and COD value in discharged waste water, and feedbacks the valve to the additionally installed high density chloride ion waste water treatment apparatus, and the high density chloride ion waste water treatment apparatus can automatically adjust the high density chloride ion waste water output amount according to the measured value.
Description
Technical field
The utility model relates to a kind of Waste Water Treatment, especially a kind of food grade polyvinylidene dichloride production of resins Waste Water Treatment.
Background technology
Food grade polyvinylidene dichloride resin is divided into two portions at the trade effluent that production process produces: a part contains high-concentration chlorine ion and organic waste water for what the monomer operation produced, and a part is the waste water of the no cl ions of production of resins operation generation.During ordinary production, discharge to sewage work after containing high-concentration chlorine ion and organic waste water and the waste water of no cl ions mixing in the comprehensive wastewater pond.The problem that exists is, when production is in full load production or the production unusual phenomenon occurs, often follow in the comprehensive wastewater cl ions takes place, COD exceeds standard, and can not discharge, and produces and has only shutdown or reduce load, has a strong impact on the steady running of production.
The utility model content
The purpose of the utility model provides a kind ofly can control the food grade polyvinylidene dichloride production of resins Waste Water Treatment that cl ions, COD exceed standard.
Realize the food grade polyvinylidene dichloride production of resins Waste Water Treatment of the utility model purpose; Comprise high-concentration chlorine ion wastewater treatment unit and comprehensive wastewater pond; Also comprise the organic matter removal device that is positioned at said high-concentration chlorine ion wastewater treatment unit water-in, be provided with the cl ions proofing unit and the COD proofing unit that link to each other with the output control pump of said high-concentration chlorine ion wastewater treatment unit respectively in the said comprehensive wastewater pond.
Said high-concentration chlorine ion wastewater treatment unit also comprises the emergency lagoon that links to each other with said organic matter removal device, and the discharge of wastewater pump discharge in said comprehensive wastewater pond links to each other with said emergency lagoon.
Said organic matter removal device comprises waste water storage tank, control pump and organic matter removal jar, links to each other successively.
The beneficial effect of the food grade polyvinylidene dichloride production of resins Waste Water Treatment of the utility model is following:
1, increase the organic matter removal device, can effectively the organism in the monomer operation waste water be removed, the waste water after the removal enters into the high-concentration chlorine ion wastewater treatment system.
2, pass through on-line measuring device; Can the chlorine ion concentration in the waste discharge, COD value be carried out on-line monitoring; And feeding back to the high-concentration chlorine ion wastewater treatment unit of setting up; The high-concentration chlorine ion wastewater treatment unit carries out the adjustment of high-concentration chlorine ion wastewater work output automatically according to this observed value, guarantees that chlorine ion concentration, the COD in the waste discharge is up to standard.
Description of drawings
Fig. 1 is the structural representation of the utility model food grade polyvinylidene dichloride production of resins Waste Water Treatment.
Embodiment
As shown in Figure 1; The food grade polyvinylidene dichloride production of resins Waste Water Treatment of the utility model; Comprise high-concentration chlorine ion wastewater treatment unit 1 and comprehensive wastewater pond 2; Also comprise the organic matter removal device 3 that is positioned at said high-concentration chlorine ion wastewater treatment unit 1 water-in; Said high-concentration chlorine ion wastewater treatment unit 1 comprises high-concentration chlorine ion wastewater treating pond 11 and output control pump 12, and said comprehensive wastewater pond is provided with the cl ions proofing unit 4 and COD proofing unit 5 that links to each other with the output control pump 12 of said high-concentration chlorine ion wastewater treatment unit 1 respectively for 2 li.Said high-concentration chlorine ion wastewater treatment unit 1 also comprises the emergency lagoon 13 that links to each other with said organic matter removal device 3, and discharge of wastewater pump 6 outlets in said comprehensive wastewater pond 2 link to each other with said emergency lagoon 13.Said organic matter removal device 3 comprises waste water water tank 31, control pump 32 and organic matter removal jar 33, links to each other successively.
The waste water storage tank 31 that high-concentration chlorine ion that produces from the monomer operation and high-COD waste water enter into organic matter removal device 3 is transported in the organic matter removal jar 33 by control pump 32,, removes the organism in the waste water through the mode of physical adsorption here.Remove organic waste water and enter into high-concentration chlorine ion wastewater treating pond 11, through waste water output control pump 12 by certain export ratio with enter into comprehensive wastewater pond 2 after the no chlorine ion wastewater of production of resins operation generation mixes.Comprehensive wastewater pond 2 is provided with cl ions proofing unit 4 and COD proofing unit 5.Two on-Line Monitor Device detect data and in time are sent in the high-concentration chlorine ion wastewater treatment unit 1; When detected data depart from objectives data; High-concentration chlorine ion wastewater output control pump 12 can accordingly be adjusted the work output of waste water, is discharged into assurance that chlorine ion concentration, COD concentration do not exceed standard in the waste water of sewage work.The waste water that enters into comprehensive wastewater pond 2 is transported to sewage work by discharge of wastewater pump 6.
When causing chlorine ion concentration in the waste water, COD concentration over-standard because of some unexpected factors, be provided with emergency lagoon 13 in the system, the waste water that will exceed standard through discharge of wastewater pump 6 is transported in the emergency lagoon 13 treats aftertreatment.
In the waste water after the food grade polyvinylidene dichloride production of resins Waste Water Treatment of the utility model is handled, contain COD＜140ppm, chlorine ion concentration＜2300ppm, qualified discharge.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; 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 the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
