Multiple-effect pollute-removing water purification agent and use method thereof

Abstract

The invention relates to a multi-effect pollution removal purifying agent and a method for applying the same. The purifying agent is complexly formed by a strong oxidant, an effective adsorbent and an assistant medicament by a weight percentage of strong oxidant 10-80%, effective adsorbent 10-70% and assistant medicament 5-50%. The surface water treatment process of using multi-effect pollution removal purifying agent of the invention comparing with the common flocculants has the following advantages: effectively improving the turbidity removal ratio, increasing the flcos formation amount and alum blossom density for the difficult coagulated surface water, improving the deposition efficiency, oxidizing and removing the organic matters in the water, eliminating the chroma and odor caused by the pollution, increasing the effluent conventional indexes, obviously improving the indexes such as oxygen consumption and ammonia nitrogen, wherein the removal rate of oxygen consumption and ammonia nitrogen can reach 25-60%, the removal rate of small organic molecules, benzenes and phenols can reach more than 80%, playing an obvious roll for the algae inactivation of lake water and reservoir water which are serious eutrophic, improving the algae removal efficiency of the deposition and filtration technologies with an algae removal rate of 80-90%, improving the coagulation efficiency, reducing 20-30% of the common flocculant dosage, effectively adsorbing the codeposition heavy-metal ion. The adding equipment of the invention is easy and convenient to use with little investment and fast effect.

Description

technical field [0001] The invention relates to a water purifying agent component, in particular to a multi-effect pollution-removing water purifying agent and its application. Background technique [0002] Most surface water sources in my country are polluted to varying degrees, and pollutants include organic matter, heavy metals, and nitrogen and phosphorus nutrients. Natural organic matter may produce color and smell; too high concentration of organic matter makes coagulation of source water difficult; nitrogen and phosphorus pollution may lead to algae growth, algae is a type of pollutant that is difficult to coagulate, and causes pollution problems such as color and algal toxins . Some seriously polluted source waters have complex water quality problems. It is difficult to solve the above problems by using common coagulants such as aluminum salts, iron salts or polymerized aluminum, so that the water quality after treatment can meet the standard. [0003] The use of ...
