Embodiment 1

[0031] Such as figure 1 As shown, the present embodiment provides a river water purification treatment system, comprising sequentially connected water intake pumping station 1, pipeline mixer 2, FA type high-efficiency fully automatic water purifier 3 and constant pressure water supply system 4; water intake pumping station 1 is provided with The lifting pump 5 is used to lift the river water source from the river channel into the pipeline mixer 2, and a flowmeter 15 is arranged on the connecting pipeline between the lifting pump 5 and the pipeline mixer 2; the pipeline mixer 2 is connected with a dosing device 6. Introduce medicines, such as NaClO, etc. into the pipeline mixer 2 through the dosing device 6, so as to realize the disinfection and coagulation treatment of waste water, and small alum flowers are formed in the water, and the distance between the dosing device 6 and the pipeline mixer 2 A metering pump 14 is provided on the connecting pipeline to accurately control...

Embodiment 2

[0040] Such as figure 2 As shown, this embodiment provides a river water purification process based on the river water purification system described in Embodiment 1, which specifically includes the following steps:

[0041] Step S1: The lifting pump 5 of the water intake pump station 1 lifts the river water to the pipeline mixer 2, and adds NaClO (sodium hypochlorite) solution into the pipeline mixer 2 through the dosing device 6 to sterilize the wastewater; at the same time, through the dosing device 6 Add PAC (polyaluminum chloride) solution into the pipeline mixer 2 to carry out coagulation treatment to the wastewater, so that the suspended matter in the water body forms fine alum flowers;

[0042] Step S2: The treated river water flows into the FA type high-efficiency automatic water purifier 3 through the pipeline, and completes the flocculation, sedimentation, filtration and backwashing processes in the water purifier;

[0043] Step S3: The purified water is discharged...

Abstract

The invention discloses a river water purification treatment system and a process, and belongs to the technical field of water quality purification. The river water purification treatment system comprises a water taking pump station, a pipeline mixer, an FA type efficient full-automatic water purifier and a constant-pressure water supply system. The process comprises steps: lifting river water from a river channel by a water taking pump to the pipeline mixer, adding two agents of PAC and NaClO into the mixer, carrying out disinfection and coagulation treatment on wastewater, then guiding the wastewater to the FA type efficient full-automatic water purifier, and completing the processes of precipitation, filtration and the like, and conveying clear effluent to all water consumption points through the constant-pressure water supply system. According to the river water purification treatment system and the process, the purification treatment effect is good, the effluent quality is excellent, the self water consumption is low, the power consumption is reduced, the occupied area is small, water and electricity are saved, manual management is not needed, the problems that an existing river water purification system is large in investment and occupied area, complex in construction and the like are solved, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a river water purification treatment system and process. Background technique [0002] With the rapid development of the national economy, the eutrophication of river water has become increasingly serious, resulting in a serious shortage of water resources and rising water prices, which have brought heavy burdens to large water users such as productive enterprises. Therefore, how to use the slightly polluted river and lake water so that it can be used by enterprises or become daily water is an urgent problem to be solved at present. [0003] The water quality of the river is not very stable due to the influence of weather, upstream sewage discharge, soil quality, etc., and also contains a large amount of sediment and other sediments. Conventional treatment processes include biochemical treatment and physical and chemical treatment. However, the conventional process wi...
