Background technology
Along with socioeconomic fast development, town and country water requirements increases day by day.Along with groundwater resources situation is increasingly serious, greatly develop and utilize the water technology of water on the ground, ensure the water yield, water quality, meeting safty of drinking water demand becomes problem demanding prompt solution.But on the ground and groundwater resources water quality deterioration and people require to improve to healthy water between contradiction expanding day, under the policy and environment of the rural area of country and cities and towns safe drinking water, newly-built and transformation is applicable to rural area and cities and towns, the centre type water works that energy-conservation, safety, investment and operation cost are lower is opportunity for whole industry, is again challenge.
In the last hundred years, drinking water treatment mainly adopts coagulating sedimentation and filtration, the method for then sterilizing, to the good underground water of water quality even only quartz sand filtration sterilize again.Needed for coagulating sedimentation, the reaction time is longer, and volume of equipment is large, and floor space is large, and cost is high, and takes up an area the coagulating sedimentation complex structure of little mechanical agitation type, and power consumption is large, and equipment failure rate is high.Economic development, water resource worsen, and simple quartz sand filtration and sterilization cannot meet the requirement of people to water quality, increase efficient biologic active carbon filtration very necessary.Develop applicable middle-size and small-size water works, technique advanced reliable, take up an area little, cost is low, energy consumption and running cost is low, automaticity is high water treatment technology and device seem very urgent.
For solving the problem, adapting to the needs in market, in order to medium and small water factory can better be adapted to, carries out modularization, combined type construction, save floor occupying area, reduce energy consumption; Existing water treatment technology basis is developed into a kind of water works water purification process and equipment.
Summary of the invention
The object of the invention is to overcome prior art deficiency, a kind of water works water purification process and device are provided
The invention provides following technical scheme:
1. water-purifying process
The ground such as reservoir or the force (forcing) pump of underground water source in water plant are along delivering to water distribution building through antiseptic pipeline, enter in vortex type high-efficient core pool after adding the medicines such as flocculant after dispensing water and complete the purification process such as preformed precipitate, flocculating setting, tube settling, gravity flow enters quartz sand filter again, gravity flow afterwards enters down the depth-type filtration of formula activated carbon filter, water purification gravity flow after dosing sterilization enters clear water reserviors, and clean water is delivered to user by supply-water pump.
2. automatically control
Whole water treatment procedure adopts PLC to control, and it is adjustable that water pump and supply-water pump are frequency conversion, and water pump, by clear water reserviors Liquid level, ensures clear water reserviors liquid level within the specific limits; Supply-water pump is controlled by the ductwork pressure transporting to user, realizes constant pressure water supply, particularly ensures the hydraulic pressure of water use peak phase.
