Problems solved by technology

[0004] However, the existing water quality improvers have unsatisfactory effects on improving acidity and alkalinity. There is no protective buffer for beneficial microorganisms or a suitable substrate for microorganisms to adhere to. The microorganisms do not have a stable place for survival and development and a buffer space, so their functions are low. The microecological adjustment effect shown is not ideal

Abstract

The invention discloses a preparing process of a coast water quality modifier. The preparing process comprises the steps of mixing materials and water, conducting uniform stirring, preparing an oyster shell aqueous solution, mixing all materials to prepare pills, conducting drying, and finally screening out the finished coast water quality modifier. Cost is low, mechanical operation is convenient, toxic metal in water can be effectively adsorbed, ammonia nitrogen in water can be decomposed, nitrite in water can be removed, fish resistance can be improved, modification effect is good, and the modifier becomes effective quickly.

Description

technical field [0001] The invention belongs to the technical field of water quality improvement, and more specifically relates to a preparation process of a seaside water quality improver. At the same time, the invention also relates to the application of a seashore water quality improver. Background technique [0002] At present, my country's water environment pollution is quite serious. Among the seven major river systems in the country, about 40% of the water quality is inferior to the fifth-class standard; 75% of the lakes in the country have varying degrees of eutrophication; The nearby sea area is seriously polluted, the frequency of red tides has increased, and the area has expanded. The pollution of water environment has directly threatened the safety of urban drinking water and people's health. Therefore, it is an urgent need for social and economic development and ecological environment construction to restore polluted rivers and lakes. [0003] With the aggrava...
