Description
Technical field
The utility model relates to
oneplant the secondary precipitation cell system that can improve organic wastewater effluent characteristics.
Background technology
Containing in organic industrial wastewater and organic wastewater treatment process, especially esterification waste water treatment process, organic wastewater first carries out coagulating kinetics again through biochemical treatment.But esterification waste water produces a lot of mud scum after biochemical treatment, after entering coagulation reaction tank, even if interpolation coagulant and flocculant are also difficult to eliminate, thus often have more mud scum in the water of pond.Too much mud scum can be unfavorable for that coagulating affects follow-up sedimentation effect, in order to improve follow-up sedimentation effect, needs the mud scum removing the coagulating basin water surface, to improve follow-up sedimentation effect.Although the mud generated through coagulating can be deposited at the bottom of pond in secondary sedimentation tank major part, also there is many mud to become mud scum and waft and float on the surface.Remove these mud scums floated on the surface that waft if collected not in time, will disperse to drift through mud scum after a period of time and in water, follow water outlet flow away, cause effluent characteristics to be deteriorated, make the COD (COD of water outlet
cr), BOD (BOD on the five
5), the content of suspension (SS), total nitrogen (TN) and total phosphorus (TP) all can increase.In order to ensure that standard water discharge often needs to remove the mud scum of the water surface.Current many dependence manually salvages mud scum, not only wastes time and energy, and artificial easily mud scum is broken up when salvaging mud scum to drift in water, to follow water outlet flow away and cause effluent characteristics to be deteriorated.
Conventional rectangular sedimentation tank, only at settling zone head design one mud-removing bucket and extraction mud pipe, arranges driving type mud scraper in pond, and the mud bottom the cleaning shoe expulsion settling zone utilizing driving type mud scraper is in bucket.But, the mud major part that organic wastewater produces through biochemical treatment is anabolite, entered the density of the mud of coagulating postprecipitation bottom settling zone only slightly larger than the density of water, if utilize the cleaning shoe of driving type mud scraper to expel these mud, mud easily floats and causes water muddy, is unfavorable for water purification.In addition, for the mud scum on the water surface, conventional rectangular sedimentation tank utilize more the scum board of driving type mud scraper along the flow direction of water by mud scum expulsion to the scum silica frost groove of pond afterbody, be unfavorable for being separated of water and mud scum like this, affect effluent characteristics.
For these reasons, exploitation is needed
onekind effectively to remove mud and mud scum that organic industrial sewage produces after coagulating treatment to improve the secondary precipitation cell system of effluent characteristics.
