摘要

The subject innovation relates to appeal purifier, (Total Reaction Powder) TRP to dissolve storage of natural inorganic coagulant containing a raw water pump, calcium and magnesium for introducing the raw water dissolving tank and for storing the PAC (Poly Aluminum Chloride) and the PAC storage tank, filter for the mixer to mix the raw water and TRP and PAC introduced by the raw water pump to remove the nutrients, and filtering the treated nutrient salts are removed through the mixer, a discharge reverse revenues, store the treated water filtered by the filter, and consists of the treatment tank to discharge to appeal. In the present design by the same configuration as is, by its own weight using a relatively large natural inorganic coagulants, increase the aggregation rate of the phosphorus and nitrogen, it is possible to prevent secondary contamination is effective as possible the advanced treatment of the raw water. In addition, the subject innovation can reduce the site area required for installation by using a simple device, it can also be installed as a removable using a vehicle, and economical, the cost of maintenance there is a significant effect to reduce as compared to conventional systems.
