Deoxygenated blood has a lower pH (due to the carbon di oxide picked up from respiring cells as a by-product), also it has a very low concentration of oxygen. On the other hand Oxygenated blood has a neutral pH and a high concentration of oxygen.
If the two were mixed together without any separation, then our body mechanism of quickly removing acidic substances and maintaining a steady supply of oxygen throughout the body would be very very slow, if not at all efficient.
major organs such as the Brain, liver, heart and kidneys would suffer instantly if such a thing happened.
Blood separation is there not only in mammals, but every other animal. However, it is much more specialized with veins, capillaries and arteries etc. In fish, for example, this system is not as developed. They have a one-way circulation. From one major artery, oxygenated blood travels around the whole body and as it moves, the concentration of O2 and co2 are altered.

It's not necessary to separate oxygenated and deoxygenated blood. What is necessary is to separate blood that's going from the heart/lungs to other organs and tissue, and blood that's coming back from organs and tissue to the heart/lungs. This forms a complete loops, which is necessary for blood to flow. You can't have blood flowing in both directions in the same tube.
The separation is simply the result of blood gaining oxygen in the lungs, and losing oxygen in muscle and tissue. You have oxygenated blood on the outbound trip, and deoxygenated blood on the inbound trip.
If you injected some oxygenated blood into the deoxygenated, inbound blood, there would not be any harmful effects. If you injected a small amount of deoxygenated blood into the outbound oxygenated blood, there would not be any harmful effects. Too much deoxygenated blood going to your brain, and you'd pass out, though.

It is necessary to separate oxygenated and deoxygenated blood in animals to efficiently process the blood for further use. If the blood goiing to a muscle had 50% of the oxygen it should have twice as much would be needed for respiration and cell metabolic functions. This would also imply the blood would have waste products floating around in it as well. This could cause a harmful buildup in the cells.

If you mix the oxygenated and deoxygenated blood together, it will reduce the overall oxygen carrying capacity in the blood and the tissues will receive less oxygen. Mammals especially need this separation because we have many typed of body tissues and they can be very thick with many layers of cells. Each tissue must receive as much oxygen as possible so that it can diffuse to all of the layers of cells within it. Other animals that are smaller or cold blooded do not need this as much because their tissues are less thick or may go for long periods of time without much blood supply.

Because oxygenated blood can rapidly be converted into available hemoglobin in the capillary vessels of the lung, and is capable of binding 60 times more oxygen than any other hemogolbin
Deoxygenated hemoglobin, is saturated already, /with CO2) and is unable to join and transport oxygen to the tissues, unless it is transformed into oxygenated blood in the lungs (by passive diffusion) until it gets rid of CO2, then it can bind oxygen and act as a carrier...
