Abstract

The invention relates to the field of biodiesel, in particular to a treating method of biodiesel sewage. The biodiesel sewage is poured into an oil-separating tank to be subjected to physical deoiling; pH value is adjusted and coagulant and flocculant are added to be subjected to activated sludge degradation; the treated biodiesel sewage is obtained after being filtered by an activated carbon filtering tank. According to the treating method of the biodiesel sewage, the biodiesel sewage is effectively treated, organic pollutants in the biodiesel sewage are removed, and biodiesel in the biodiesel sewage can further be effectively recycled to achieve recyclable utilization of resources.

Description

A kind of processing method of biodiesel wastewater
Technical field
The present invention relates to field of biodiesel oil is and in particular to a kind of processing method of biodiesel wastewater.
Background technology
At present, domestic oiliness sewage treatment technology mainly has chemicals logos and bioanalysises, and chemicals logos is mainly Oil is less than the density of water, and available gravity carries out detached principle, and the equipment generally adopting has oil interceptor, oil water separator, gas Floating machine, coagulating sedimentation and absorbent charcoal adsorption tank etc..Bioanalysises refer under suitable temperature, ph, nutrient substance and Oxygen Condition, Using the Strong oxdiative degradation function of microorganism, wastewater organic pollutant is removed clean method.Mainly there is anaerobic pond and aerobic Two kinds of pond device.For biodiesel wastewater oil content big, float, cod, bod concentration are high the features such as, need to adopt chemicals The device that logos and bioanalysises combine.At present, the domestic device lacking effective process biodiesel wastewater, generally adopts single Oil interceptor, oil water separator, the equipment such as air floatation machine and coagulating sedimentation, these equipment can remove in waste water more than 80% dynamic plant Thing oil and float, it can however not removing most organic pollution, also have using unit equipment, due to lacking in equipment Few device such as efficient anaerobic pond and activated carbon filtering tank, last water outlet also has a small amount of organic pollution, leads to effluent quality Do not reach the first discharge standard of country, surrounding aqueous environment is caused with certain pollution.
Content of the invention
The present invention is directed to the deficiencies in the prior art, provides one kind can either effectively process biodiesel wastewater, particularly Remove organic pollution therein, enable the processing method of the biodiesel wastewater of resource recoverable again.
The technical solution adopted in the present invention is:
A kind of processing method of biodiesel wastewater, comprises the following steps:
By biodiesel wastewater after grid, carry out physics in input oil interceptor and deoil；Reclaim the floating of oil interceptor upper strata Oil；
Biodiesel wastewater after oil removal is processed adjusts ph value and adds coagulant and flocculant, is stirred reacting；
Then enter back into coagulative precipitation tank to staticly settle；
Coagulative precipitation tank biodiesel wastewater uasb reactor out, carries out activated sludge degraded；Uasb reactor goes out Water sequentially enters anoxic pond and Aerobic Pond carries out anoxia and aerobic biodegradation organic impuritiess；
Enter back in biogenic sediment pond and staticly settled；
Biogenic sediment pond biodiesel wastewater out again through activated carbon filtering tank filtration after processed after biology Diesel oil waste water.
A kind of processing method of biodiesel wastewater that the present invention provides, effectively processes biodiesel wastewater, removes it In organic pollution moreover it is possible to effectively reclaim the biodiesel in biodiesel wastewater, realize the recoverable of resource.
Specific embodiment
The present invention is further illustrated with reference to embodiments, but the present invention is not limited only to these embodiments, not On the premise of departing from present inventive concept, any improvement made is within the scope of the present invention.
A kind of processing method of biodiesel wastewater, comprises the following steps:
By biodiesel wastewater after grid, carry out physics in input oil interceptor and deoil；Reclaim the floating of oil interceptor upper strata Oil；
Biodiesel wastewater after oil removal is processed adjusts ph value and adds coagulant and flocculant, is stirred reacting；
Then enter back into coagulative precipitation tank to staticly settle；
Coagulative precipitation tank biodiesel wastewater uasb reactor out, carries out activated sludge degraded；Uasb reactor goes out Water sequentially enters anoxic pond and Aerobic Pond carries out anoxia and aerobic biodegradation organic impuritiess；
Enter back in biogenic sediment pond and staticly settled；
Biogenic sediment pond biodiesel wastewater out again through activated carbon filtering tank filtration after processed after biology Diesel oil waste water.

Claims (1)

1. a kind of processing method of biodiesel wastewater is it is characterised in that comprise the following steps:
