Solutions to the problem
These are the treatment of waste that the industries should follow
Synthetic organic materials including solvents, paints, pharmaceuticals, pesticides, coking products and so forth can be very difficult to treat. Treatment methods are often specific to the material being treated. Methods include Advanced Oxidation Processing, distillation, adsorption, vitrification,incineration, chemical immobilisation or landfill disposal. Some materials such as some detergents may be capable of biological degradation and in such cases, a modified form of wastewater treatment can be used.
Acids and alkalis can usually be neutralised under controlled conditions. Neutralisation frequently produces a precipitate that will require treatment as a solid residue that may also be toxic. In some cases, gasses may be evolved requiring treatment for the gas stream. Some other forms of treatment are usually required following neutralisation.
Waste streams rich in hardness ions as from de-ionisation processes can readily lose the hardness ions in a buildup of precipitated calcium and magnesium salts. This precipitation process can cause severe furring of pipes and can, in extreme cases, cause the blockage of disposal pipes. A 1 metre diameter industrial marine discharge pipe serving a major chemicals complex was blocked by such salts in the 1970s. Treatment is by concentration of de-ionisation waste waters and disposal to landfill or by careful pH management of the released wastewater.
Toxic materials including many organic materials, metals (such as zinc, silver, cadmium, thallium, etc.) acids, alkalis, non-metallic elements (such as arsenic or selenium) are generally resistant to biological processes unless very dilute. Metals can often be precipitated out by changing the pH or by treatment with other chemicals. Many, however, are resistant to treatment or mitigation and may require concentration followed by landfilling or recycling. Dissolved organics can be incinerated within the wastewater by Advanced Oxidation Process
Our experiments revealed
Analysis of data ,ragi grows well and good in the soil that is been affected by the industrial effluent.this crop originally needs the soil texture of less nitrogen content .as per potassium permanganate test the soil we sampled has low nitrogen content so it is suitable for the growth of ragi.farmers feel that it is very difficult to grow the crops in the infected feild without synthetic fertilisers .so it is better to grow ragi in these type of feild.for more high yield the organic fertilisers are also added
Leather ash mixed with leather effluent contaminated soil, which is largely made up of silicon dioxide and calcium oxide, can be used as a substitute for Portland cement, or as a supplement to it. The materials which make up leather ash are pozzolanic, meaning that they can be used to bind — or cement — materials together. Pozzolanic materials, including leather ash cement, add durability and strength to concrete.
Leather ash cement is also known as green concrete. It binds the toxic chemicals that are present in the leahter ash in a way that should prevent them from contaminating natural resources. Using leather ash ash cement in place of or in addition to Portland cement uses less energy, requires less invasive mining, and reduces both resource consumption and CO2 emissions. It gives great turgidity for the buildings and one of the good recycling methods
Govt implement
The govt can implement many plans to promote the plant cultivation reduce the interest and prevent the construction of the industries near agricultural field. Govt should also support the people Who live in the areas and also give implementation to municipalities to make landfills without depositing in the land or water.
The agronomist should make a public mating and say what types of crops can be grown
These methods should be implemented by the govt
The leather effluent can be recycled and used as a condenser for any hot substance. After a long time of freezing the substance loses its strength and when it is treated its parameter will be very small
what we have made
we made 4 experiments on in (1)bacteria culture,(2)borosilicate glass,(3)industrial condenser method and leather ash cement(4)grown finger millet
we formed a "yellow ribbon club" in our society.
