The buildings which do not have a sewage system can _____________.
-
Construct drainage tanks
-
Construct septic tanks
-
Construct sewage water bodies
-
Construct septic canals
Septic tanks are underground tanks in which sewage is collected and allowed to decompose with the use of bacteria. Drainage tanks are used to remove water. Sewage pollutes the water bodies when directly discharged into water bodies like river. Septic canal is a tubular passageway for the disposal for sewage.
In compositing, volume of solid waste is
-
Reduced
-
Enhanced
-
Burnt
-
Removed
Pollution due to sewage can be reduced by
-
Creating separate chemical toilets.
-
Constructing septic tanks.
-
Letting off drainage in rivers.
-
Both A and B.
- A septic tank is an underground chamber made of concrete, fiberglass or plastic through which domestic wastewater flows for basic treatment. Settling and anaerobic processes reduce solids and organics, but the treatment efficiency is only moderate. Septic tank systems are a type of simple onsite sewage facility.
- Chemical toilet is a toilet that is not connected to a sewage system but has a compartment in which waste is treated with chemicals for temporary storage.
- Letting off drainage in rivers will cause water pollution.
Which is correctly matched?
$1$. Arsenic poisoning- Black foot disease
$2$. Secondary Effluent treatment- Biological process
$3$. Pyrolysis- Solid soil waste disposal
$4$.
Tubifex- Water pollution indicator
$5$. Biomagnification - Degradable pollutants
-
$1, 2, 3, 5$
-
$1, 3, 4, 5$
-
$2, 3, 4, 5$
-
$1, 2, 3, 4$
-
$1, 2, 4, 5$
- Arsenic poisoning causes black foot disease as arsenic is a carcinogen that results in darkening of the skin and abdominal issues.2. Secondary treatment to the effluents involves a biological process in which the organic matter in the effluent is decomposed by the bacteria and fungi.3. Pyrolysis is the process in which the solid soil is subjected to the high temperature to decompose it into ash.4. Tubifex is a roundworm that can sustain the polluted water that has low levels of dissolved oxygen and heavy metal deposition. So, its growth in any water body indicates water pollution.5. Biomagnification is the ability of the non-degradable pollutants to stay in the adipose tissues of the living organisms and persist in higher concentration.Hence, the correct answer is '1,2,3,4'.
