What are the consequences of discharging sewage?

1) Dead Organic Matter:

Hazards: Deplete dissolved oxygen in the water, endangering the survival of fish.

This leads to a lack of oxygen in the water, resulting in the death of microorganisms that need oxygen. And it's these aerobic microorganisms that decompose organic matter and sustain the self-purification of rivers and streams. The consequences of their death are:

Rivers and streams turn black and smelly, and toxins accumulate and harm people and animals.

2) Organic and Inorganic Chemicals:

Hazards: Most organic chemicals are toxic, and their entry into rivers and lakes can poison or poison aquatic organisms and cause ecological damage.

Some organic chemicals can accumulate in aquatic organisms and cause poisoning after human consumption.

Water contaminated with organic chemicals is difficult to purify, and the safety and health of human drinking water are threatened.

Hazards: Causes algae in the water.

Soaring. Because phosphorus is an important element that all living things need for growth. In nature, phosphorus is the element.

Seldom. When phosphorus-laden sewage is discharged into the lake, the algae in the lake become rich in nutrients and grow dramatically (called eutrophication).

Resulting in a bacterial bloom in the lake. The wild algae grew thicker and thicker on the surface of the water, and finally some of them were crushed under the surface of the water, and they died because they couldn't see sunlight. The bacteria at the bottom of the lake use dead algae as nutrients and multiply rapidly.

Fish kills, lakes die. The proliferating bacteria consume the oxygen in the water, causing the lake to become hypoxic, and the fish that depend on oxygen to survive die, and then the bacteria will also die due to the lack of oxygen, and eventually the lake will age and die.

Available for the tropics.

of coastal waters pose the threat of eutrophication of water bodies similar to the upper-velocity situation.

4) Petrochemical detergents.

Hazards: Most of the detergents are petrochemical products, which are difficult to degrade, and discharge into the river will not only seriously pollute the water body, but also accumulate in aquatic products, and people will be poisoned after eating.

5) Heavy metals (mercury, lead, cadmium, nickel, selenium, arsenic, chromium, thallium, bismuth, vanadium, gold, platinum, silver, etc.).

Hazards: Direct physiological toxicity to humans and animals.

Irrigating crops with water containing heavy metals can contaminate crops with heavy metals, making agricultural products toxic.

It is deposited at the bottom of the river, in the bay, and enters the food chain through aquatic plants.

It enters the human body through aquatic products such as fish.

6) Acids: (e.g., sulfuric acid).

Hazards: Poisoning aquatic plants.

Causes the death of fish and other aquatic organisms.

Severe damage to the ecosystems of streams, ponds and lakes.

6) Suspended solids:

Hazards: Reduces water quality, increases the difficulty and cost of purifying water.

Modern household waste has many components that are difficult to degrade, such as plastic packaging materials. When they enter the river, they are not only very harmful to aquatic life (they die if ingested), but also block the river.

7) Oily substances:

Hazards: Damage to the ecological environment of aquatic organisms and reduce fishery production.

Contaminating aquatic food endangers human health.

Spills from oil tankers in the ocean can cause large numbers of marine animals (from fish and shrimp, seabirds to seals, sea lions. etc.).

Polluting rivers, groundwater, and air can have serious consequences.

The hazards posed by industrial wastewater are as follows:

1. Pollution of organic wastewater and inorganic wastewater containing non-toxic substances. Some pollutants are not toxic in themselves, but they are harmful to water bodies due to their large amounts or high concentrations. For example, when the amount of organic matter discharged into the water body exceeds the allowable amount, the water body will have anaerobic decay; When a large amount of inorganic flows in, the concentration of salts in the water body increases, causing changes in osmotic pressure, and causing adverse effects on organisms (plants, animals and microorganisms).

2. Pollution of organic wastewater and inorganic wastewater containing toxic substances. For example, pollution caused by acute toxic substances such as cyanide and phenol, chronic toxic substances such as heavy metals, and carcinogenic substances. Poisoning methods include contact poisoning (mainly neurotoxicity), food poisoning, erosive poisoning, etc.

3. Pollution containing a large amount of insoluble suspended solids wastewater. For example, cellulose from the pulp and fiber industries, fine dust emitted from coal preparation and mineral processing, and lime sand emitted from the ceramics and quarrying industries. These substances are deposited at the bottom of the water to form "toxic sludge", and there are many examples of poisoning incidents.

In the case of organic matter, spoilage occurs, giving the water body an anaerobic state. These substances can also block the gills of fish in the water, causing breathing difficulties and disrupting spawning grounds. Please refer to the relevant technical documentation for details.

4. Pollution caused by oily wastewater. Oil floating on the surface of the water is both unsightly and can emit an unpleasant odor. Oils with low ignition points are also at risk of disaster. Animal and vegetable fats and fats are spoiling and consume dissolved oxygen in water bodies.

5. Pollution caused by wastewater with high turbidity and high color. It causes insufficient luminous flux and affects the growth and reproduction of organisms.

6. Pollution caused by acidic and alkaline wastewater. In addition to being harmful to living things, it can also damage equipment and equipment.

7. Pollution caused by wastewater containing a variety of polluting substances. Chemical reactions occur between various substances, or chemical reactions occur under the action of natural light and oxygen and produce harmful substances. For example, sodium sulfide and sulfuric acid produce hydrogen sulfide, and ferrocyanide salts are photodecomposed to produce cyanide.

8. Pollution caused by industrial wastewater such as nitrogen and phosphorus. In closed waters such as lakes, the inflow of wastewater containing nitrogen and phosphorus substances can cause abnormal growth of algae and other aquatic organisms, resulting in eutrophication of water bodies.

Discharging sewage is an act of suspected environmental pollution. Whoever violates state regulations by discharging, dumping, or disposing of radioactive wastes, wastes containing infectious disease pathogens, toxic substances, or other harmful substances, seriously polluting the environment, is to be sentenced to up to three years imprisonment or short-term detention and/or a fine; where the circumstances are serious, the sentence is between three and seven years imprisonment and a concurrent fine.

The penalty conditions for discharging sewage are as follows:

1. Discharging, dumping, or disposing of radioactive wastes, wastes containing infectious disease pathogens, or toxic substances in key protected areas designated in accordance with law, such as drinking water source protection zones and core nature reserve core protection areas, where the circumstances are especially serious;

2. Discharging, dumping, or disposing of radioactive wastes, wastes containing infectious disease pathogens, or toxic substances into the waters of important rivers and lakes designated by the state, where the circumstances are particularly serious;

3. Causing the loss of the basic functions of a large amount of permanent basic farmland or suffering permanent damage;

4. Causing serious injury or illness to many people, or causing serious disability or death. Where conduct in the preceding paragraph simultaneously constitutes another crime, follow the provisions for the heavier punishment at trial and sentencing.

Legal basisArticle 338 of the Criminal Law of the People's Republic of China.

Crime of polluting the environment] Whoever violates state regulations by discharging, dumping, or disposing of radioactive waste, waste containing infectious disease pathogens, toxic substances, or other harmful substances, seriously polluting the environment, is to be sentenced to up to three years imprisonment or short-term detention and/or a fine; where the consequences are especially serious, a sentence of between three and seven years imprisonment and a concurrent fine is to be given.

The discharge of sewage will affect the survival of organisms and plants in the water, affect the quality of groundwater, affect the health of the environment, etc., these adverse effects will bring serious harm to people, and if it is a chemical area, the sewage also contains a lot of chemicals, hindering the recycling of water resources.

How individuals can do a good job of environmental protection.

Minimize the use of white plastic and disposable items on weekdays, and use cloth bags or biodegradable plastic bags when shopping.

Choose low-carbon travel and drive as little as possible, because car exhaust is a harmful substance, which can reduce the harm to the environment caused by car exhaust emissions.

Do a good job of garbage classification, do not litter, garbage classification can promote the effective recycling of resources, reduce environmental pollution.

1.affect the survival of animals in the water (such as fish and shrimp), and seriously lead to their death;

2.Affecting the quality of groundwater, causing humans to get sick after drinking contaminated water;

3.Affect environmental sanitation The sewage discharged has a foul smell, which will attract a lot of mosquitoes and flies, and affect the quality of life of people living in these areas;

4.The sewage discharged by chemical companies contains a lot of chemicals, and the water cannot be used for drinking, even for watering vegetables, which brings many difficulties to the reuse of water resources.

1. Cause acute and chronic poisoning.

Water bodies can be poisoned through drinking water or the food chain when they are contaminated with toxic and harmful chemicals. Minamata disease and pain disease are commonly caused by water pollution.

2. Carcinogenic. Long-term consumption of carcinogenic water or consumption of organisms (e.g. fish) that accumulate carcinogens in the body may cause cancer.

3. Indirect impact.

When water is polluted, it often worsens the organoleptic properties of the water. For example, although certain concentrations of pollutants do not directly harm human health, they can cause water to produce odors and colors, foam and oil films, etc., which hinder the normal use of water bodies.

The direct impact is that the sewage discharged from the sewage discharge flows into the sea, which is a major threat to all life in the sea. This is the most directly affected and most directly affected organism. <>

In the ocean, we know that there are a lot of marine life, if you have dived into the water, you will know that the bottom of the sea is very beautiful, and all the fish and shrimp, all the marine creatures are very energetic, they do not walk on land, do not appear on the earth, only live in the water generation after generation, which is actually a state of life in harmony with nature for us. But if we humans discharge sewage, it will directly affect their homes and will be a big threat to marine life. If the sewage discharge is severe, it will affect our drinking water.

In many of our poor areas, there is no water to drink, not even bad water, and in some places the water is sewage, and a professional water purification processor is needed to treat the water before we can drink it. So the sewage discharge is very important for us, but it is also very dangerous. Imagine what would you do if you turned on the faucet and the water that came out was all dirty, and there was no way to treat it?

At that time, even if we started to lose sewage and started to save water, this consequence was the same. There is no way to get it back. Many, many chemical companies have chemical elements in the sewage discharged after experiments, and this water is not to mention that we humans can drink it, even plants can't drink it.

Therefore, in our daily life, the indiscriminate discharge of sewage will have a very bad impact on the environment. As the saying goes, water is the source of life, and while we live in harmony with nature, we are also reaping all that nature has given us. So for water, we must be economical.

For some sewage, we must discharge it effectively.

We must take good care of us, and the beautiful is the home on which we live.

Sewage discharge will first affect some organisms in the water, and it will also affect the quality of groundwater.

There is less and less potable water. Sewage will seep into the groundwater, polluting the groundwater and making it impossible for people to drink it, and there will be less fresh water resources to drink in the future.

Sewage discharge will cause serious pollution of environmental water resources, pollute the surrounding environment, affect the beauty of the environment, pollute the land, etc., and the overall impact on the environment is very great.

It will bring serious pollution to the environment. As a result, our air is no longer fresh, and it will also affect our health.

Sewage discharge can have a bad impact on the environment, pollute water sources, and make people sick.

The harm of water pollution caused by indiscriminate sewage discharge is multifaceted, and the following is an introduction to the impact of water pollution on human health.

1.Causes acute and chronic poisoning. Water bodies can be poisoned by drinking water or the food chain when they are contaminated with toxic and harmful chemicals. The famous Minamata disease and painful disease are caused by water pollution.

2.Carcinogenicity. Certain carcinogenic chemicals such as arsenic, chromium, nickel, beryllium, aniline, benzo(a)pyrene and other polycyclic aromatic hydrocarbons and halogenated hydrocarbons can be adsorbed by suspended solids and sediments, and can also accumulate in aquatic organisms.

3.Water-borne infectious diseases occur. Biological pollutants such as human and animal feces pollute water bodies and may cause bacterial intestinal infections such as typhoid, dysentery, enteritis, cholera, etc.

Common intestinal viruses such as poliovirus, coxsackievirus, infectious hepatitis virus, etc., can cause corresponding infectious diseases through water pollution. 1989 Shanghai"Hepatitis A events", which is caused by water pollution. In developing countries, about 60 million people die each year from diarrhoea, mostly children.

4.Indirect impacts. After the water body is polluted, it can often cause the deterioration of the sensory properties of the water, such as some pollutants at a certain concentration, although there is no direct harm to human health, but it can make the water have a peculiar odor, different color, foam and oil film, etc., hindering the normal use of the water body.

Copper, zinc, nickel and other substances can inhibit the growth and reproduction of microorganisms at a certain concentration, thereby affecting the decomposition and biological oxidation of organic matter in water, reducing the self-purification ability of water bodies and affecting the health status of water bodies.
