Abstract
The invention provides a method for treating ABS sewage, which adopts a comprehensive method combining physicochemical treatment and biochemical treatment, sewage enters a regulating tank through a fine grid, air is introduced to ensure uniform water quality, and the two flocculation and sedimentation separation processes are adopted, so that the SS content in the ABS sewage can be effectively removed, the biodegradability of the ABS sewage is improved, the investment is small, the sewage treatment effect is good, and better economic and social benefits are achieved.
Description
Technical field
The present invention relates to a kind of method of sewage disposal, especially handle the method for ABS sewage.
Background technology
ABS sewage mainly results from IM-ABS and SAN workshop section drying stage and washing tower, principal pollutant are vinylbenzene, vinyl cyanide etc. in the waste water, the waste water of industry ABS discharging, impurity is very complicated in the water, existing sewage disposal technology adopts coagulation more---and air-float method is handled, effect is undesirable, can not reach emission request
Summary of the invention
The purpose of this invention is to provide a kind of sewage water treatment method that can effectively remove impurity.
For realizing that technical scheme provided by the present invention is:
A kind of method of handling ABS sewage, it is characterized in that the comprehensive method that adopts materialization and biochemical treatment to combine, sewage enters equalizing tank, bubbling air by fine fack, make water quality even, add defoamer, after water pump lifting, enter first flocculation basin, by flocculation agent and gravity, make supernatant liquor flow into activated sludge tank, after the outflow of the first settling tank gravity, enter the active sludge aeration tank, the water part after the processing enters second pond, part mud returnedactivatedsludge aeration tank, precipitation, gravity flow into three heavy ponds, and three heavy pond supernatant liquors efflux, for mud concentrates and the dehydration part, one heavy pond mud, second pond part excess sludge, three heavy pond mud are squeezed into sludge thickener through pump, flow into the sludge dewatering device through pump again, the mud outward transport is disposed.
Present method adopts twice flocculation and settlement separate technology, effectively removes the content of suspended substance in the ABS sewage, improves the Biodegradability of Wastewater energy, reduces the organic loading of follow-up sewage, reduces the generation of pipeline latch up phenomenon.
Embodiment
In the actual treatment, the comprehensive method that adopts materialization and biochemical treatment to combine, sewage enters equalizing tank, bubbling air by fine fack, make water quality even, add defoamer, after water pump lifting, enter first flocculation basin, by flocculation agent and gravity, make supernatant liquor flow into activated sludge tank, after the outflow of the first settling tank gravity, enter the active sludge aeration tank, the water part after the processing enters second pond, part mud returnedactivatedsludge aeration tank, precipitation, gravity flow into three heavy ponds, and three heavy pond supernatant liquors efflux, for mud concentrates and the dehydration part, one heavy pond mud, second pond part excess sludge, three heavy pond mud are squeezed into sludge thickener through pump, flow into the sludge dewatering device through pump again, the mud outward transport is disposed.
Treatment preparation method thereof of the present invention is following steps:
1. adjust the equalizing tank water-in: equalizing tank is open-air open type, because the processing wastewater water temperature more than 50 ℃, for avoiding the influence of high temperature to active sludge, is adjusted the water-in of equalizing tank, makes the equalizing tank water-in away from water outlet, is beneficial to the waste water heat radiation;
2. increase active sludge nutrition: during sludge acclimatization in the early stage, because processing wastewater has certain toxicity, acclimation period elongates, for active sludge is grown as early as possible, regulate its pH value between the 6-8 with mineral acid, add aluminum chloride hydrocarbon complex, thorough mixing under mechanical stirring, to between the 6-8, add aluminum chloride hydrocarbon complex, thorough mixing under mechanical stirring with inorganic acid for adjusting pH value;
3. adjust the position of flocculation agent pipeline: the size of being convenient to observe flocculation agent quantity, be beneficial to quick stirring again, accelerating flocculation generates, the add-on of aluminum chloride is ABS sewage by weight: aluminum chloride hydrocarbon complex=10000: 2-3, add polyacrylamide thorough mixing under mechanical stirring, the add-on of polyacrylamide is ABS sewage by weight: polyacrylamide=300000: 1-2;
4. canvas press cloth: the cleaning of canvas press cloth is made up of scavenging pump, water source and shower etc., clean hydraulic pressure and reach 4 kilograms, because the thickened sludge recirculation water contains a large amount of particulate matter greater than nozzle diameter, therefore plug nozzle very easily, it is bad to cause cleaning, stay the mud mark on the filter cloth, the press filtration effect reduces, and needs mediation in time;
5. ABS sewage is left standstill in the polymerization of alkali formula, forms water and throw out two-phase, and water directly discharging enters follow-up sewage-farm, and sediment is carried out solid-liquid separation, and parting liquid returns the pH value and regulates the operation recycling processing, and solid matter is recovered;
Below in conjunction with embodiment content of the present invention is described further:
Embodiment one
Equipment: equalizing tank, flocculation agent pipe, pressure filter;
Treatment process:
1. adjust the equalizing tank water-in: equalizing tank is open-air open type, because the processing wastewater water temperature more than 50 ℃, for avoiding the influence of high temperature to active sludge, is adjusted the water-in of equalizing tank, makes the equalizing tank water-in away from water outlet, is beneficial to the waste water heat radiation;
2. increase active sludge nutrition: during sludge acclimatization in the early stage, because processing wastewater has certain toxicity, acclimation period elongates, for active sludge is grown as early as possible, regulate its pH value between the 6-8 with mineral acid, add aluminum chloride hydrocarbon complex, thorough mixing under mechanical stirring, to between the 6-8, add aluminum chloride hydrocarbon complex, thorough mixing under mechanical stirring with inorganic acid for adjusting pH value;
3. adjust the position of flocculation agent pipeline: the size of being convenient to observe flocculation agent quantity, be beneficial to quick stirring again, accelerating flocculation generates, the add-on of aluminum chloride is ABS sewage by weight: aluminum chloride hydrocarbon complex=10000: 2-3, add polyacrylamide thorough mixing under mechanical stirring, the add-on of polyacrylamide is ABS sewage by weight: polyacrylamide=300000: 1-2;
4. canvas press cloth: the cleaning of canvas press cloth is made up of scavenging pump, water source and shower etc., clean hydraulic pressure and reach 4 kilograms, because the thickened sludge recirculation water contains a large amount of particulate matter greater than nozzle diameter, therefore plug nozzle very easily, it is bad to cause cleaning, stay the mud mark on the filter cloth, the press filtration effect reduces, and needs mediation in time;
Embodiment two
Batching: aluminum chloride hydrocarbon complex, polyacrylamide, its treatment process is with embodiment one.
In sum, the present invention adopts twice flocculation and settlement separate technology, can effectively remove SS content in the ABS sewage, improves the biodegradability of ABS sewage, and invests for a short time, and it is effective to dispose of sewage, and better economic and social benefit are arranged.
