Abstract
The invention relates to the technical field of wastewater treatment, particularly a flocculant for slaughter wastewater, which is composed of the following components in parts by weight: 5-15 parts of polyaluminium chloride-polyacrylamide, 10-20 parts of polyphosphate, 8-10 parts of polyvinyl imidazoline and 5-15 parts of lignosulphonate. The flocculant has the characteristics of high efficiency and broad spectrum, can adapt to a wide pH value range of water quality, and has favorable effects within the pH value range of 4-11; the removal rate of grease and SS (suspended sediment) is higher than 95.12%, and is 98.26% at the maximum; the removal rate of COD (chemical oxygen demand) is higher than 92.21%, and is 95.39% at the maximum; the removal rate of BOD (biochemical oxygen demand) is higher than 86.33%, and is 92.85% at the maximum; and thus, the flocculant has obvious flocculation effect on slaughter wastewater, and is simple to prepare.
Description
Technical field
The present invention relates to technical field of waste water processing, more specifically a kind of flocculation agent for slaughterhouse wastewater.
Background technology
Slaughterhouse wastewater comes from hutch flushing, drip washing, butcher and other factory building terrace rinses, scalds hair, analyses, non-staple foodstuff processing, washing oil etc.By its water quality, originate, we can know in waste water mainly contains blood, grease, meat mincing, bone slag, hair and ight soil etc., and waste water is maroon, has stronger stench taste.Organic suspended matter content is high, easily corrupt, enters water body and can consume the dissolved oxygen in water, destroys the ecosystem, contaminate environment.
In the process of butchering with meat processing, consume a large amount of water, get rid of again the waste water that contains the pollution substances such as blood stains, grease, hair, meat bits, livestock and poultry offal foreign material, indigested foodstuff and ight soil simultaneously, and in this type of waste water, also contain in a large number to human health harmful microorganism.Meat processing waste water, as not treated direct discharge, can cause severe contamination to water surrounding, and human and livestock health works the mischief.
The contained pollution substance of meat processing waste water mostly belongs to and is easy to biodegradable organism, at them, enters after water body, can promptly consume the dissolved oxygen in water, cause fish and hydrobiont because of anoxic dead; Because anoxic also can make water body, change anaerobic state into, can make like this water quality deterioration, produce stink, affect health.Meanwhile, the pathogenic microorganism meeting amount reproduction in waste water, harm people ' s health.To butchering meat processing waste water, process, removing its pollution is very necessary to preserving the ecological environment with human health.
In slaughterhouse wastewater, suspended solid SS is up to 1000mg/L, and it belongs to the organism of easy corruption, and its COD and BOD that can affect waste water causes water quality variation.
And slaughterhouse wastewater enters biochemical stage after pre-treatment, during need to add flocculation agent to make the suspended particulates flocculating settling in waste water reach the object separated with water, increase water quality, and for the About Flocculating Effect of Flocculant of slaughterhouse wastewater, fall flat at present.
Summary of the invention
Goal of the invention of the present invention is for above deficiency, and the flocculation agent that is specifically designed to slaughterhouse wastewater that a kind of flocculating effect is good is provided.The present invention is achieved by the following technical solutions:
For a flocculation agent for slaughterhouse wastewater, by following component by weight, formed:
As a kind of optimization, above-mentioned flocculation agent is comprised of following component by weight:
