THE METHODS DISPOSING OF THE POULTRY MANURE

There are many methods for the disposing of this wastes, like:

-Physical

-Biological

-Chemical

-Mixed or hybrid

These methods can use for disposing of these wastes, but the main point is the volume of disposing of not all of the methods can work for the huge or big volume of manure.

The unique method can treat the big volume of poultry manure is the physical by direct high-temperature drying (Incineration), which can treat it's with low consumption & big productivity, the end products are very safe because will be without microorganisms factors & without wet (moisture), can use this end product in several fields like reusing the dry material in Soil fertilization, use it as the material can enter in the animal food production, can use it as a type of sand which can use in the concrete of cement, & others, & can re-use thermal power to produce heat water or/& warming the farms or building.

Some facts about the test:

The wastes wet was 70-80 %

The component of the wastes is a mix (litter or faecal of poultry & straw).

The working temperature is from 300 – 800C (300 to make products 12-14 % wet, for the 1-3% wet, working temp. is 800) this temperature is according to the properties of the end-products need.

The incineration efficiency will be about 3 t/h, or 72 t/d, for the wastes which contain 70-80% wet & the results were about 51 tons was evaporated as steam & the dry remains was about 21 tons.

Information

100 000 hens need about 1600 hectares for the spreading methods of the wastes or manure

100 000 layers of hen flocks, which kept in cages produce wastes more than 12 t/d that mean 4380 t/y

If using 340-400 0C drying system when the input wet of waste about 80% the end product will be 8-14% wet, & then increase the temp. will give less wet in the end products.

The new technologies for the dryer (Incinerator) use secondary chamber & cyclone to remove the smell produced from the drying process & also be environmental clean gas.

Hybrid method

Use the wastes from the hen farms, by making it as a culture for earthworms or any other insects & then entered to the incinerator will be given output rich with dry proteins & minerals products which can use for several fields like (earth fertilizing, reusing in the feed of the fish, poultry & animals, can use also in the concrete & others), also can reuse thermal power to warming the farms or building.
