Formula of preparation for sewage treatment

Abstract

The invention discloses a formula of a preparation for sewage treatment. The formula comprises silicon dioxide, aluminum oxide, calcium oxide, potassium oxide, ferric oxide, magnesium oxide, sodium oxide and titanium dioxide, wherein the silicon dioxide accounts for 66 to 69 percent, the aluminum oxide accounts for 15 to 17 percent, the calcium oxide accounts for 3.5 to 5.5 percent, the potassiumoxide accounts for 2 to 3 percent, the ferric oxide accounts for 3 to 5 percent, the magnesium oxide accounts for 1.5 to 3 percent, the sodium oxide accounts for 0.5 to 1.5 percent, and the titanium dioxide accounts for 0.5 to 1.5 percent. The formula is simple and convenient to use, cannot be affected by an external environment, and can effectively reduce contents of COD (Chemical Oxygen Demand),ammonia nitrogen, total phosphorus, total nitrogen and SS (Suspended Solid) in sewage; decolorization is effectively carried out, the activity of aerobic microorganisms is excited, a bed mud biological system is recovered, a better treatment and control effect on black and odorous water bodies, scattered sewage discharge holes and water bodies having relatively-sealed systems also can be achieved, secondary pollution is effectively avoided, self-adjustment restoration of an aquatic ecosystem is realized, a sewage treatment problem is radically solved, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and purification of water resources, in particular to a preparation formula for sewage treatment. Background technique [0002] Pollutants in my country's rivers and lakes are divided into direct pollutants and indirect pollutants. The sources include domestic waste water and industrial production sewage, such as the random discharge of industrial sewage from electroplating factories, paper mills, pharmaceutical factories, printing and dyeing factories, and chemical factories. The pollution of the water body is very serious; domestic sewage contains a large amount of detergent and domestic garbage seepage liquid, which will increase the content of nitrogen and phosphorus elements in the water body, and aggravate the degree of eutrophication of the water body; The pesticides and fertilizers absorbed by the crops continue to enter the river with the rain, leading to eutrophication of the wate...

AI Technical Summary

Problems solved by technology

The first method: sewage interception and storage network, artificial aeration, dredging treatment and ecological water exchange. The sewage interception and storage network needs to have a full-coverage sewage pipe network system and centralized treatment system. The project volume is large and the cost is high, and the implementation is difficult; Through artificial aeration and adsorption of heavy metal adsorbents, the oxygen supply environment of the sediment can be changed, the concentration of dissolved oxygen in the water body can be increased, the activity of aerobic microorganisms in the water body can be enhanced, and the degradation rate of pollutants can be increased. However, it takes a long time for the complete degradation of pollutants. It is difficult to achieve a good treatment effect on black and odorous water bodies or relatively closed water bodies; the amount of sludge in the dredging process is large and the composition is very complex. Refractory organic matter, heavy metals, salts, and pathogenic microorganisms and parasite eggs, etc. The organic matter content in the sludge is high, which is easily corrupted and produces stench. A large amount of untreated sludge is piled up and discharged indiscriminately. secondary pollution, it also occupies a large amount of land resources, and the cost of transportation and landfill is high; ecological water exchange can quickly improve water quality, but pollutants in water are easily diffused and exported, and its essence is the transfer of pollutants rather than emission reduction. fundamentally solve the problem

The second method: the use of chemical flocculants, chemical oxygenation, chemical algae removal and heavy metal fixation can quickly control and alleviate pollutants in the water body, but it is easy to kill all fish, shrimp and antioxidant bacteria in the water. Turning into stagnant water will cause secondary pollution to the water resource ecosystem, and the pollution situation is very easy to rebound

The third method: use biological bacteria agent, plant purification and biological control method. The biological bacteria agent has strong impact resistance and can increase the biodiversity of water body, but it is greatly affected by the external environment, it is easy to lose and take effect slowly, and the treatment cycle is long; The purification method includes not only plants, but also animals and microorganisms. On the basis of ensuring the stability and safety of slope protection, the goal is to create biodiversity in slope protection. The exchange of matter, energy and information between systems, etc.) is very dynamic. Plant purification not only has a landscape effect, but also restores polluted river water and creates a healthy urban river ecosystem, such as building artificial wetlands. And ecological floating islands, but they have high requirements for light and dissolved oxygen, and later management and maintenance are difficult; biological regulation can increase the biodiversity of water bodies, and remove pollutants from water bodies through food chains, but they have certain requirements for water body environments, and the effect is slow , there is a risk of alien species invasion
