Human waste Disposal Technology In Simple
Human waste disposal technology for rural areas are certainly different from the technology of latrines in urban areas . Therefore , the technology of latrines in rural areas , besides fulfilling the requirements of a healthy latrine as described above , should also be based on sociocultural and economic rural communities . Types of latrine appropriate rural technologies are as follows :
2.1 pit latrines and latrine ( Pit Latrine )
The pit latrines in rural areas often encountered in Java . But it is often found that less than perfect pit latrines , for example, without a home and without a toilet lid . So the easy entry of insects and smells can not be avoided . Besides, because there is no latrine house , when the rainy season arrives then it will be full of toilet water .
Another thing to note here is that the pit latrine should not be too deep . Because if too deep will contaminate ground water beneath . The depth of the pit latrine ranged from 1.5-3 meters. In keeping with the rural outhouse house can be made of bamboo , bamboo walls and thatch or leaf rice . Distance from the source of drinking water for at least 15 meters .
2.2 Ventilated pit latrines ( Ventilation Improved Pit Latrine Latrine = VIP )
This is similar to the latrine pit latrines , the difference is more complete , the ventilation pipe . For rural areas , the vent pipe can be made with bamboo .
2.3 Latrines Pond ( Fishpond Latrine )
This latrine built over a fish pond . In this pond occur latrine system recycling ( recycling ) , the stool can be eaten fish , eat the fish , and then pull out the feces are eaten , and so on .
This pond has a latrine that function while preventing environmental contamination by feces , can also add protein for the people ( generate fish ) .
2.4 Fertilizer Latrines ( the Privy Compost )
In principle, this latrines such as pit latrines , only shallower dig . Besides, it is also privy to dispose of animal waste and garbage , leaves . The procedure is as follows :
ü At first create a regular pit latrines ..
ü bottom layer of its own , put litter leaves.
ü Over it put dirt and grime biinatang ( if any) of each day .
ü After approximately 20 inches , covered with leaves lagii trash , then put the dirt again .
ü Continue until full .
ü Once fully backfilled soil and membuatt new latrines .
ü Approximately 6 months later dipergunakkan fertilizer plant .
2.5 Septic Tank
Latrin type of septic tanks is the way that best meets the requirements , therefore , this kind of excreta disposal is recommended . Septic tanks consists of a watertight sedimentation tank where faeces and wastewater go in and decompose . In this tank , the stool will be for a few days
In this tank , the stool will be for several days . During this time the stool will have two processes , namely :
2.5.1 Chemical Processes
As a result of the destruction of the stool will be reduced and the majority ( 60-70 % ) solids will settle ( deposition) in the tank as sludge . Substances that can not be destroyed along with the fat and foam will float and form a layer that covers the surface of the water in the tank . This layer is called the scum which serves to maintain an anaerobic atmosphere of fluid underneath , which allows anaerobic bacteria and facultative anaerobic bacteria can thrive , which will serve the next process .
2.5.2 Biological Processes
In this process of decomposition through the activity of anaerobic bacteria and facultative anaerobic consuming natural organic substances , sludge and scum . The result , in addition to gas formation and other liquids , is also reducing the volume of sludge to allow the septic tank is not full speed . Then the liquid enfluent 've not contain feces and parts have relatively low BOD . This enfluent fluid eventually flows out through the pipe and into the permeation place .
Deposition on septic tanks
septic tank is the most fulfilling requirements , therefore , how this kind of excreta disposal is recommended . Septic tanks consists of a watertight sedimentation tank where faeces and wastewater go in and decompose . Feces from going through the toilet drain pipe pvc then through the exhaust pipe pvc divider which then goes into the tank septic tank
