行なわなければならない。[Prior Art] Currently, blood produced as a byproduct at slaughterhouses is simply discarded. This causes problems such as water pollution, and the pollution of rivers progresses, so when blood or the like is discharged into rivers, wastewater must be treated.
この廃水処理としては、−船釣に活性汚泥法による生物

処理液が分離しにくくなる等の問題である。However, since blood wastewater is mainly composed of proteins, it is difficult to be assimilated by aerobic microorganisms, and various problems arise if blood is treated as wastewater using activated sludge or the like. For example, residual C0D (chemical oxygen demand) and B
Because OD concentration (biological oxygen demand) does not easily decrease,
The generation of anaerobic bacteria causes problems such as bad odors and sludge bulking, which makes it difficult to separate sludge and treatment liquid.

Another object of the present invention is to provide a method for efficiently processing blood by pre-treating it.

る血液廃水の処理方法である。[Means for Solving the Problems] As a result of intensive research in order to solve the above-mentioned problems, the present inventors have decomposed blood with a proteolytic enzyme in advance, and then treated it with activated sludge or the like. The present invention was completed by discovering that blood can be treated as wastewater more efficiently. That is, the present invention is characterized in that in treating blood wastewater using a biological oxidation method using an activated sludge method, blood is decomposed using a protease, and then the treated liquid is treated using an activated sludge method. This is a method for treating blood wastewater.
以下、本発明をさらに詳細に説明する。The present invention will be explained in more detail below.
本発明において用いられる蛋白質分解酵素としては、蛋
白質を分解する酵素であれば特に限定するものではなく
、例えば、パパイン、トリプシン、サーモライシン等の
通常一般に用いられる蛋白質分解酵素があげられる。The protease used in the present invention is not particularly limited as long as it decomposes proteins, and includes commonly used proteases such as papain, trypsin, and thermolysin.

蛋白質分解酵素の粉末等を添加したりすることかあげら
れるか、処理の容易性の点から水溶液等に蛋白質分解酵
素を溶解したものを血液に添加することが好ましい。The means for decomposing blood using proteolytic enzymes is not particularly limited; for example, a solution of proteolytic enzymes dissolved in an aqueous solution or the like may be added to blood, or a powder of proteolytic enzymes may be added to blood. From the viewpoint of ease of treatment, it is preferable to dissolve a proteolytic enzyme in an aqueous solution or the like and add it to the blood.
なお、本発明での血液における蛋白質分解酵素の濃度と
しては、特に限定するものではないが、経済性を考慮す
ると１〜１０００ｍｇ／Ωになるように調節するのが好
ましい。Note that the concentration of proteolytic enzyme in blood in the present invention is not particularly limited, but in consideration of economic efficiency, it is preferably adjusted to 1 to 1000 mg/Ω.
さらに、このときに処理する血液濃度は薄すぎると経済
効率が悪く、また、濃すぎると機器の操作性に支障をも
たらすおそれがあるので蛋白質濃度として、１〜３０％
程度の血液を処理するのが好ましい。Furthermore, if the blood concentration to be processed at this time is too thin, it will be economically inefficient, and if it is too thick, it may interfere with the operability of the equipment, so the protein concentration should be 1 to 30%.
It is preferable to process blood of a certain degree.
このように調整した溶液は、使用する蛋白質分解酵素と
その際に使用する量により差があるが、おおよそ温度１
０〜６０℃で、反応時間１〜２４時間程度処理した後、
活性汚泥などを用いて通常の廃水処理を行なう。The solution prepared in this way varies depending on the proteolytic enzyme used and the amount used, but the temperature is approximately 1.
After processing at 0 to 60°C for a reaction time of about 1 to 24 hours,
Perform normal wastewater treatment using activated sludge, etc.

果を有する。[Effects of the Invention] By treating blood wastewater using the method according to the present invention, the proteins contained in the treated blood are degraded, compared to directly treating blood with activated KN. Since it is easily assimilated by aerobic microorganisms, the residual COD concentration and BOD concentration can be reduced, and as a result, no foul odor is generated, which has the effect of efficiently treating wastewater.
