class RUFAS.routines.manure.manure_treatments.slurry_storage_outdoor.SlurryStorageOutdoor(weather: Weather, time: RufasTime, manure_treatment_config: ManureTreatmentConfig)#

Bases: BaseManureTreatment

Class for the outdoor slurry storage.

Attributes:

All attributes inherited from BaseManureTreatment. In addition, the following attributes are defined: storage_time_period: RufasTime in days that the manure is stored in the manure

treatment system, days.

freeboard_input: Empty storage space above the manure in the treatment system.: onto the treatment system.

__init__(weather: Weather, time: RufasTime, manure_treatment_config: ManureTreatmentConfig) → None#

Initializes the outdoor slurry storage manure treatment.

Args:: weather: A Weather object. time: A RufasTime object. manure_treatment_config: A ManureTreatmentConfig object containing

the configuration data for the manure treatment system.

property wastewater_volume: float#

property treatment_volume: float#

Calculates the minimum treatment volume.

Returns:: The minimum treatment volume, m^3.

property total_pit_volume: float#

Calculates the total pit volume.

Returns:: The total lagoon pit, m^3.

property pit_depth: float#

Returns the depth of the pit.

Returns:: The depth of the pit, m.

property pit_slope: float#

Returns the slope of the pit.

Returns:: The slope of the pit, dimensionless.

_calc_abc() → Tuple[float, float, float]#

Calculates the coefficients a, b, and c for volume calculations.

Returns:: A tuple containing the coefficients a, b, and c for volume calculations.

property pit_width: float#

Returns:: The additional pit volume needed for precipitation, m^3.

property freeboard_volume: float#

Calculates the additional pit volume needed for freeboard.

Returns:: The additional pit volume needed for freeboard, m^3.

_adjust_final_manure_volume(current_day_final_manure_volume: float) → float#

Adjust the final manure volume to account for the precipitation and the storage time period.

Parameters#

current_day_final_manure_volumefloat: The final manure volume for the current simulation day (\(m^3\)).

Returns#

float: The adjusted final manure volume.

calc_methane_emission(accumulated_liquid_manure_total_volatile_solids: float, accumulated_liquid_manure_total_degradable_volatile_solids: float, accumulated_liquid_manure_total_non_degradable_volatile_solids: float) → Tuple[float, float]#
