Problems solved by technology

The physical treatment method is the simplest water treatment method, which recovers the insoluble suspended pollutants in the sewage through physical separation. The physical treatment method can only deal with some simple wastewater treatment, but the treatment is very incomplete and it is difficult to meet the discharge standard; The biological treatment method is to dissolve the pollutants in the sewage through microbial metabolism, but this method requires a large investment and high operating costs

Abstract

The invention discloses an efficient composite water treatment agent and a preparation method thereof. The preparation method comprises the following steps that 1, raw materials of polyacrylamide, polyaluminum chloride, polymerized ferrous sulfate, palygorskite, a synergist and activated carbon are weighed; 2, the raw materials are evenly mixed to obtain the efficient composite water treatment agent. According to the efficient composite water treatment agent and the preparation method thereof, combination of the organic matter and the inorganic matters is used for sewage purification, the efficient composite water treatment agent has multiple kinds of medicine effects and functions, the flocculating settling speed is high, the flocculating settling effect is good, moreover, the preparationtechnology is simple and low in cost and can be widely used for treating various kinds of industrial sewage and municipal sewage, not only is the quality of sewage treatment improved, but also the cost of the water treatment agent is reduced, the treatment effect is stable, and thus the efficient composite water treatment agent and the preparation method thereof are suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a high-efficiency composite water treatment agent and a preparation method thereof. Background technique [0002] Water is an indispensable natural resource for human production and life, and also an environmental resource on which organisms depend. With the intensification of the water resource crisis and the continuous deterioration of the water environment quality, the shortage of water resources has become one of the world's most concerned resource and environmental problems. one. Therefore, saving water, treating sewage, and developing new water sources are very important, and vigorously developing water treatment methods will play a vital role in solving the technical problem of water resource shortage. [0003] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and...
