The technical answer is because you have let the anaerobic breed at the expense of the aerobic ones. Both types break down the waste but the aerobic ones create far less smell. As you do not specify the type/model of toilet saying "come back up" makes me think it is probably a nice simple sump through. If you are using conventional blue it will kill the somewhat weaker aerobic bacteria so I would advise that you change to a biological holding tank treatment but you will need to give the tank a really good flush and then put us with a period of smell while the remaining blue is purged from the system and the aerobic bacteria gets established. Choose a treatment that says it contains bacteria and enzymes. You also need a flow of air over the fluent. Ideally a breather at each end of the tank with an i.d. of not less than 1" but the larger the better. If you have a macerator or vacuum toilet you may also have charcoal filter on the breather. When these are regularly changed they tray smells from the breather but tend to stop air reaching the tank. In summer you may well have to pump out every week but in the cooler months I find I can go for weeks between pump outs. It may help to put some yoghurt down the toilet when you first change from conventional blue to seed the bacteria. Some people swear by just adding yeast to the tank, others use sceptic tank treatment. Other additives people recommend are Biomagic, Odourloss and the one I prefer is by The New Blue Loo Company.

PS another problem that can occur is that the tank does not hold enough liquid to submerge the solids.
