Abstract
The invention discloses a treatment method of turpentine production wastewater. The treatment method comprises following steps: 1) turpentine production wastewater is collected from workshops, and is delivered into an oil separator so as to remove floating oil, and at the same time, the oil separator is used for adjusting water quantity and water quality; 2) wastewater obtained via floating oil removing is delivered into an air floating tank using a pump, and a flocculating agent is added so as to remove emulsified oil in wastewater; 3) water obtained via air floatation is delivered into an electrolytic tank for electrolysis using an electric filter, water discharged from the electrolytic tank is delivered into a regulating tank, 10% of diluted sulfuric acid is added so as to adjust pH value to 7 to 7.5; 4) obtained water is delivered into a biosorption and biological aerated filter for biochemical treatment, and up-to-standard release of obtained water is realized via an end sedimentation tank. The treatment method can be used for appropriate treatment of turpentine production wastewater; up-to-standard release of wastewater is realized; and environmental pollution is avoided.
Description
Technical field
The present invention relates to turps and extract field, be specifically related to a kind for the treatment of process of turps factory effluent.
Background technology
Turps is a kind of natural essential oil, it is the mixture of the multiple terpene hydro carbons based on firpene, there is distinctive chemically reactive, for coating, artificial camphor, Terpineol 350, synthetic perfume, medicine, synthetic resins, the aspect industrial chemicals such as organic chemical industry, apply very extensive, but terebinthine extracting method is unreasonable in prior art, be mainly manifested in, the process for turps factory effluent is improper, causes the waste water of discharge not up to standard, pollution of ecological environment, brings potential threat to the health of the mankind simultaneously.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind for the treatment of process of turps factory effluent, this treatment process is proper to terebinthine production wastewater treatment, makes the wastewater to reach standard of discharging, avoids environmental pollution.
Object of the present invention carrys out specific implementation by the following technical programs:
A treatment process for turps factory effluent, comprises the following steps:
1) first turps factory effluent imports oil trap by each workshop and removes oil slick, and oil trap has been held concurrently the water yield and water quality regulation effect simultaneously;
2) then by pump by removing oil slick after waste water lifting to air flotation pool, by add flocculation agent removing waste water in oil in water emulsion;
3) air supporting water outlet carries out electrolysis by electrofiltration machine in electrolyzer, and electrolyzer water outlet enters equalizing tank, regulates pH to 7 ~ 7.5 by the dilute sulphuric acid adding 10%;
4) enter biological adsorption again and BAF carries out biochemical treatment, water outlet is finally through final deposition pool qualified discharge.
Further, in step 1), within oil slick 2-4 days in described oil trap, reclaim once.
Further, in step 3), 4) in, the mud cake outward transport after plate-and-frame filter press dehydration in sludge treating system of the scum silica frost of air supporting and electrolysis and the biochemical excess sludge produced.
The treatment process of a kind of turps factory effluent of the present invention, comprises the following steps: 1) first turps factory effluent imports oil trap by each workshop and remove oil slick, and oil trap has been held concurrently the water yield and water quality regulation effect simultaneously; 2) then by pump by removing oil slick after waste water lifting to air flotation pool, by add flocculation agent removing waste water in oil in water emulsion; 3) air supporting water outlet carries out electrolysis by electrofiltration machine in electrolyzer, and electrolyzer water outlet enters equalizing tank, regulates pH to 7 ~ 7.5 by the dilute sulphuric acid adding 10%; 4) enter biological adsorption again and BAF carries out biochemical treatment, water outlet is finally through final deposition pool qualified discharge, and this treatment process is proper to terebinthine production wastewater treatment, makes the wastewater to reach standard of discharging, avoids environmental pollution.
Embodiment
The treatment process of a kind of turps factory effluent described in the embodiment of the present invention, comprises the following steps:
1) first turps factory effluent imports oil trap by each workshop and removes oil slick, and oil trap has been held concurrently the water yield and water quality regulation effect simultaneously;
2) then by pump by removing oil slick after waste water lifting to air flotation pool, by add flocculation agent removing waste water in oil in water emulsion;
3) air supporting water outlet carries out electrolysis by electrofiltration machine in electrolyzer, and electrolyzer water outlet enters equalizing tank, regulates pH to 7 ~ 7.5 by the dilute sulphuric acid adding 10%;
4) enter biological adsorption again and BAF carries out biochemical treatment, water outlet is finally through final deposition pool qualified discharge.
Preferably, in step 1), within oil slick 2-4 days in described oil trap, reclaim once.
Preferably, in step 3), 4) in, the mud cake outward transport after plate-and-frame filter press dehydration in sludge treating system of the scum silica frost of air supporting and electrolysis and the biochemical excess sludge produced.
The present invention is proper to terebinthine production wastewater treatment, makes the wastewater to reach standard of discharging, avoids environmental pollution.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
