sewage disposals hurt a big part of the environment. When it all gets dumped into rivers and lakes, it uses up the dissolved oxygen the fish need to live. Also, when its not properly collected, the garbage gives a foul smell that causes air pollution. Another example of how it hurts the environment is the rejected garbage could damage the vegetation and the ground by putting chemicals in the sediment.
hope this answers your question!
C. Treated sewage is less damaging to the environment than untreated sewage
how does sewage treatment affect household chemicals how does sewage treatment affect household chemicals
Sewage is carried out of city's with sewage pipes that leads to rivers, oceans and seas. The problem with that method, is sewage pollution, which could have malicious effects on the environment.
yes they do
As long as sewage tanks do not leak, they make no difference to the environment. Many homes across north America are not on municipal sewer and therefore have to have sewage tanks to separate waste before the black water goes to the septic field. In good shape these do not hurt the environment.
Sewage activity is necessary as it transports all you waste to a designated area such as a landfill or te incineration plant. Without these, you would have to keep your waste in your house until the waste truck comes to pick it up everyday. This would waste lots of time and money. This would definitely affect cleaniness and hygiene in the areas.
Human migration, in big enough numbers, puts pressure on the environment. Humans generally pollute the environment in many ways, even when they try not to. Sewage, road-building, tree-felling and air-pollution are just a few of the effects.
Landfills affect our human health because, the landfill is filled in by waste disposals and all that waste disposals goes in the air we breath in which causes pollution. Pollution can cause eye burning, and also there saying that some chemicals might be able to cause cancer.
Yes it pollutes them
Sewage(raw) can effect the environment,as it could harm different species of animals. If animals are to interfere with it, it might kill them. It pollutes the environment,so we will no longer have fresh, clean waters.
sending the sewage to a biological water treatment plant
* When sewage is not properly collected and transported to sewage treatment plant in a sanitary way, sewage emanates foul odour causing air pollution and gives room for mosquito breeding leading to spread of diseases. * When sewage is discharged into river bodies without proper treatment, organic matters present in sewage causes depletion of dissolved oxygen which in turn affect aquatic eco system existing in the water bodies * Some gases like methane, carbon-di-oxide, sulphur-di-oxide, etc. are formed in sewage and escape into atmosphere causing air pollution and acclerating global warming by green house gases.
