Abstract

The invention discloses a water treatment composite preparation, which is prepared from, by weight, 300-600 parts of polyaluminum chloride; 1-4 parts of polyacrylamide; 700-1000 parts of fly ash. Thewater treatment composite preparation has two performances of a coagulant and adsorbent, combines a coagulation sedimentation unit and an adsorption filtering unit into a whole, saves occupied space,is simple to operate and low in early-stage investment, and can further reduce COD and remove chroma and turbidity aiming at sewage subjected to biochemical treatment, an adsorbent does not need to bereplaced, nor backwashing equipment are arranged, the subsequent investment is less, and the cost of sewage treatment can be greatly reduced.

Description

technical field

[0001] The technical field of sewage treatment of the present invention specifically relates to a water treatment compound preparation and its preparation method and use method. Background technique

[0002] Industrial sewage is generally pretreated first, and then undergoes secondary biochemical treatment. If the effluent index does not meet the standard, advanced treatment is required. Advanced treatment methods include coagulation precipitation method, adsorption method, ozone oxidation method, catalytic oxidation method, Fenton reagent method, etc. Among them, the methods with good treatment effect, strong adaptability and simple operation mainly include coagulation-sedimentation method and adsorption method.

[0003] The coagulation and sedimentation method is to add coagulants and coagulants to the sewage, and after stirring, the colloids, suspended particles and other pollutants in the sewage are destabilized and aggregated into flocs, which are preci...
