Embodiment 1

[0020] When the present invention works, first open the water inlet valve 4 of the water inlet pipe at the bottom of the electrocoagulator 5, so that the raw water after preliminary filtration enters the electrocoagulator 5, and the current density range of the electrode 1 is controlled by the control relay 2 in the process of treatment. 35A / m 2 , to achieve the degree of electrocoagulation that controls current regulation. At the same time, the flow rate is adjusted through the cooperation of the flow meter 3 and the water inlet valve 4 . The hydraulic retention time was 15 minutes and the applied voltage was 36 volts.

[0021] After the electrocoagulation treatment is completed, the water enters the static pipeline flocculation device 6, and the effective residence time of the water in the static pipeline flocculation device 6 is 5 minutes. The mud is discharged once every hour, and the time of mud discharge is 1.0min.

[0022] After static flocculation, the impurities in...

Abstract

The invention discloses a rural drinking water integrated water purification method and device. The method comprises the steps of integral coagulation, precipitation and filtration. The integral coagulation comprises the following steps: coagulating in an electrocoagulation mode, and sending into a static pipeline flocculation plant to carry out mixed flocculation. In the electrocoagulation process, an aluminum sheet is used as the electrode, an up-flow electrocoagulation device reacts with aluminum ions generated by the aluminum sheet, and then the mixed flocculation is carried out. In the mixed flocculation process, water is precipitated and subjected to clearance drainage, and is filtered through activated carbon. The electrocoagulation water purification method can complete the process of electrocoagulation, electric flotation, electrolytic oxidation, electrolytic reduction and the like in one facility, has the functions of condensation, adsorption, upward flotation, redox and the like, comprehensively considers the economic cost, and has the characteristics incomparable with other techniques when being used in a minitype integrated facility. The method and device have favorable removal effect on turbidity, and have certain removal effect on chroma and COD (chemical oxygen demand).

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an integrated water purification method and device for drinking water in rural areas. Background technique [0002] At this stage, 71% of the rivers and lakes in our country are polluted to varying degrees, the annual use of chemical fertilizers and pesticides in rural areas is increasing, and the quality of shallow groundwater is generally deteriorating. There are more than 190 million people with excessive levels of harmful substances in their drinking water. For these geographically remote rural areas, it is not realistic to build large-scale water plants in a centralized manner and then radiate to these areas. It is more realistic to establish integrated small-scale water purification equipment, take advantage of its high efficiency and miniaturization characteristics, and carry out separate water supply through a certain combination. However, there is a lack of pro...
