Abstract

The invention relates to a coagulation ceramic membrane combined rural drinking water treatment device. The device comprises a coagulation unit (1), a ceramic membrane unit (2), a transfer control unit (3) and a clear water area ultraviolet digestion unit (4) which are sequentially connected in series, wherein the coagulation unit (1) is provided with a water inlet pipe (11), a tubular mixer (14)and a coagulant feeding pump (13), and the water inlet pipe (11) is connected with the ceramic membrane unit (2); the tubular mixer (14) is arranged on the water inlet pipe (11); and the coagulant feeding pump (13) and the water inlet pipe (11) are connected to the front end of the tubular mixer (14). Compared with the prior art, the method has the advantages of improving the water treatment efficiency of short-flow integrated equipment, being suitable for rural drinking water treatment and the like.

Description

technical field [0001] The invention relates to the field of water treatment devices, in particular to a rural drinking water treatment device with coagulation ceramic membranes. Background technique [0002] Compared with conventional water plants with civil structures, integrated water treatment equipment has the characteristics of small footprint, little impact on topography, low investment price, simple operation and management, low operating cost and stable effect, and is more suitable for rural areas. Water treatment infrastructure needs. At present, the integrated sewage treatment facilities mainly focus on the A / O process, MBR process, oxidation ditch process, biological filter process, etc., and the integrated coagulation-sedimentation-filtration conventional water purification process is mostly used for drinking water, such as SDJ, LEJI, LEGS type water purifiers, some equipment have optimized the process through enhanced coagulation and other methods. However, d...
