Organic wastewater is the wastewater that mainly slows down the withering and stagnant potato organic pollutants, and the organic wastewater is easy to cause eutrophication of water quality, which is relatively harmful. Organic wastewater generally refers to wastewater discharged from industries such as papermaking, leather and food products above 2000mg l.

Highly organic wastewater includes domestic sewage, food processing and papermaking and other industrial wastewater, which contains organic substances such as carbohydrates, protein differences, oils, lignin and so on.

Organic wastewater is the wastewater dominated by organic pollutants, and organic wastewater is easy to cause eutrophication of water quality, which is relatively harmful. Organic wastewater generally refers to wastewater discharged from papermaking, leather and food industries above 2000mg l. These substances exist in the effluent in suspension or dissolution and can be decomposed by the biochemical action of microorganisms.

It needs to consume oxygen during its decomposition, so it is called a depleting oxygen pollutant. This contaminant can cause a decrease in dissolved oxygen in the water, affecting the growth of fish and other aquatic organisms. When the dissolved oxygen in the water is depleted, the organic matter undergoes anaerobic decomposition, resulting in unpleasant odors such as hydrogen sulfide, ammonia and mercaptans, which deteriorates the water quality.

The composition of organic matter in water is very complex, and the concentration of ozone-depleting organic matter is often expressed by the amount of oxygen consumed during the biochemical decomposition of ozone-depleting substances per unit volume of water.

Organic waste liquid generally refers to wastewater containing organic compounds, which is mainly wastewater discharge in chemical, pharmaceutical, dye, pesticide and other industries and production processes. Generally speaking, organic waste liquid carries sails with a large amount of organic substances, such as benzene, petroleum ethers, phenols, ketones, acids, esters, fats, hydrocarbons, etc. These substances not only pose a threat to the human body and the environment, but also are difficult to degrade and treat, becoming one of the main water pollution.

The different components and properties of organic waste liquid have a great impact on its treatment methods and costs. There are many ways to treat organic waste liquid, including comprehensive utilization, biochemical treatment, bioreactor treatment, fluidized bed treatment, activated sludge method, membrane filtration method, adsorbent treatment, etc. Different treatment methods have their own characteristics and limitations, and it is necessary to select the appropriate treatment method according to the specific situation of organic waste liquid, and implement appropriate pretreatment work.

In addition to the treatment method, reducing the generation of organic waste liquid is also an important environmental protection measure. Vertical production methods should be used to improve the process flow, improve the quality of products, and effectively control the discharge of wastewater to reduce the generation of organic waste liquid. In addition, reasonably strengthen the governance and management is also an important environmental protection step to solve the pollution of organic rock head waste liquid, the state should introduce the coarse hidden number of laws and regulations and industry standards, the organic waste liquid classification, qualitative, identification and classification, improve the discharge supervision and management system, at the source to control and reduce the generation of organic waste liquid, improve treatment efficiency, and protect the ecological environment.

In conclusion, organic waste liquid is a type of wastewater composed of organic matter, which is widely present in industrial production and has a negative impact on the environment and human health. In order to effectively solve the environmental and health problems caused by organic waste liquid, it is necessary to comprehensively adopt relevant technologies to effectively reduce the amount of waste liquid generated. At the same time, it is also necessary to establish laws, regulations and industry standards to supervise the behavior of enterprises and citizens, and jointly ensure the harmonious and stable development of the natural environment.

1. Mercury-containing wastewater.

Mercury-containing wastewater is mainly used in non-ferrous metal smelters, chemical plants, pesticide factories, paper mills, dye factories and thermal instrument factories. Methods for removing inorganic mercury from wastewater include sulfide precipitation, chemical coagulation, activated carbon adsorption, metal reduction, ion exchange and microbial methods. Generally, alkaline mercury-containing wastewater is usually treated by chemical coagulation or sulfide precipitation.

2. Heavy metal wastewater.

Heavy metal wastewater mainly comes from the wastewater discharged from mining, smelting, electrolysis, electroplating, pesticides, pharmaceuticals, paints, pigments and other enterprises. The types, contents and forms of heavy metals in wastewater vary with different production enterprises. Since heavy metals cannot be decomposed and destroyed, they can only transfer their location and transform their physical and chemical forms.

3. Cyanide-containing wastewater.

Cyanide-containing wastewater mainly comes from electroplating, gas, coking, metallurgy, metal processing, chemical fiber, plastics, pesticides, chemical and other sectors. Cyanide-containing wastewater is a kind of toxic industrial wastewater, which is unstable in water and is easy to decompose, inorganic cyanide and organic cyanide are highly toxic substances, and human ingestion can cause acute poisoning.

4. Wastewater from the paper industry.

Papermaking wastewater mainly comes from the two production processes of pulping and papermaking in Tongyan in the paper industry. Pulping is to separate the fibers in the plant raw materials of the spring wheel family, make slurry, and then bleach; Papermaking is to dilute, shape, press, and dry the slurry to make paper.

Both processes discharge large amounts of wastewater. The wastewater produced by pulping is the most polluted. The wastewater discharged during pulp washing is black-brown, called black water, and the concentration of pollutants in black water is very high, with BOD as high as 5-40g L, containing a large amount of fiber, inorganic salts and pigments.

5. Chemical industry wastewater.

The wastewater of the chemical industry mainly comes from the production wastewater discharged from the petrochemical industry, coal chemical industry, acid and alkali industry, fertilizer industry, plastic industry, pharmaceutical industry, dye industry, rubber industry, etc.

The main measures for the prevention and control of chemical wastewater pollution are: firstly, the production process and equipment should be reformed, pollutants should be reduced, wastewater discharge should be prevented, and comprehensive utilization and development should be carried out; The degree of treatment of wastewater that must be discharged should be selected according to the quality of water and requirements.

It can be treated with organic flocculants, which are divided into ionic and non-ionic types.

Ionic organic flocculant can not only change the surface charge of particles, but also play a bridging chain role to cause flocculation. Such as polyacrylamide (also known as 3 flocculants). It is used to accelerate the rapid sedimentation of concentrate in dense ponds.

This results in lower concentrate water content and less metal loss. The molecular weight of organic flocculants is generally large, usually tens of thousands, hundreds of thousands, or even millions, so adding a small amount can play a role as a bridge.
