(4) in addition to flocculant, disinfectant feeding device are set, assistant medicament throwing device is also provided with, when water source occurs Some index abnormal conditions, can be by adding assistant medicament, such as when manganese is exceeded, basicity is relatively low, pH is relatively low, turbidity is higher Increase potassium manganate demanganization；Add refined lime to improve basicity and pH value, can also add NaOH to improve pH value；Flocculation aid can be added to improve flocculation Effect, ensure effluent quality, it is very common that the index, which abnormal condition occurs in reservoir and mountain stream water source,；

(5) highly intensive, saving soil；

(6) cost of investment is low, water producing cost is low；

(7) it is applied widely, especially suitable for water supply infrastructure it is poor, be located in outlying rural area, industrial and mineral, island, army, School；

(8) facility water supply scale is finished product, modularized design to thousands of cubic meters per number of days cubic meter, using flexible, Various emergent or disaster relief situations are also applied for use；

(9) construction time is short, upper detective；

(10) individual layer filtrate is used, back washing strength is easily controlled, and filterins media run-off is few；

(11) air water back washing is used, backwash effect is good, and water quality is more guaranteed, and water-saving result is good；

(12) pressure type contacts filter, head-tank, valve, pipeline are all 304 stainless steels, and sanitary condition is good, Service life is grown.

Embodiment is not construed as the limitation to utility model, but it is any be based on spiritual improvements introduced of the present utility model, All should be within the scope of protection of the utility model.
