Problems solved by technology

[0017] However, it has been found through production practice that the bactericidal rate of the above-mentioned patent is 90-93% after 18 days, and it is still difficult to meet the demand for long-lasting efficacy in the industry. Once the efficacy of the drug fails or the high bactericidal rate cannot be maintained for a long time, it will directly affect the oil recovery yield and quality
[0018] After analysis, there are two reasons why the bactericidal effect of the authorized patent CN103478164B of China Petrochemical Corporation is difficult to last: (1) With the extension of time, nano-titanium dioxide is prone to agglomeration due to its unique surface properties, and the treatment agent Dodecyl dimethyl benzyl ammonium chloride or octadecyl dimethyl benzyl ammonium chloride as a surfactant cannot provide long-term dispersion effect for nano-titanium dioxide. Once titanium dioxide is agglomerated, its adsorption and thermal Stability will be greatly reduced, thereby affecting the overall bactericidal effect; (2) as time prolongs, the bactericidal effect of sodium hypochlorite or potassium hypochlorite as a bactericide / oxidant will decline, and the bactericidal mechanism of sodium hypochlorite or potassium hypochlorite relies on its own oxidation properties, and this oxidizing property will decline with the change of environment and time, and finally affect the overall bactericidal effect

Abstract

The invention relates to a deep cleaning sewage treatment process which includes the steps: firstly, performing standing and sedimentation treatment on sewage; secondly, adding sewage treatment agentsinto the sewage, and enabling the quality of the sewage reaches the standard; finally, filtering the sewage. The sewage treatment process can treat industrial sewage and is high in efficiency and lowin cost, sustainable sterilization is achieved, the highly polluted industrial sewage is purified, so that the treated sewage is colorless and tasteless and can reach the emission standard, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to a deep clean sewage treatment process. Background technique [0002] While the economy continues to develop today, a series of problems have also emerged, such as the production of industrial sewage and domestic sewage is increasing year by year, and the shortage of water resources is becoming more and more serious. In 1972, the United Nations Conference on the Human Environment for the first time proposed that "after the oil crisis, the next crisis is water". Especially for China, a country with a large population, the problem of water shortage is even more serious, and it is one of the 13 major water-scarce countries. The average water resource per capita is 1 / 4 of the world's average. The recycling of sewage is one of the important ways to solve the shortage of water resources and protect the water environment. [0003] As far as my country's oilfields are concerned, with the end of oilfield exploitation, the amount of wat...
