Problems solved by technology

The main disadvantages of the above-mentioned technology are: the bucket groove and the sand guide bottom sill are easy to deposit, and dredging is inconvenient, which may easily cause water intake facilities to increase water loss due to long-term deposition, increase raw water turbidity in dry seasons, and affect anaerobic fermentation of sludge Water quality and other issues affect the normal production of waterworks

Abstract

The invention discloses a water intaking and desilting system for high-turbidity water and a water intaking and desilting method thereof; the water intaking and desilting system for high-turbidity water comprises a water intaking body, an inflow commutating zone which is connected with the water intaking body and used for forming a low speed inflow channel for depositing sludge; an impulse suction dredge is arranged in the inflow commutating zone; a water absorbing well which is conncted with the inflow commutating zone and used for promoting the raw water; a pipeline system which is connected with the water absorbing well and used for transferring the water in the water absorbing well to a water treatment plant through a water pump. A water intaking and desilting method for high-turbidity water comprises the following steps: setting the inflow commutating zone, depositing the big particulate matter in the water of the zone; promoting the water after rectification; transferring the water after rectification. The system and the method have the advantages that the mud is discharged at fixed period for the low speed inflow channel which is easy to have deposition; the function of the raw water for washing deposition is combined for saving the water and energy, reducing inflow sediment, simplifying management and ensuring the stability of raw water quality.

Description

technical field [0001] The invention relates to the field of high turbidity water intake and cleaning, in particular to a high turbidity water intake and desilting system and a method thereof. Background technique [0002] The influent water of urban waterworks in my country contains a variety of organic and inorganic substances, most of which exist in the form of sedimentation. Usually, these substances are removed by sedimentation after entering the waterworks through water intake facilities. The water intake structures that use high-turbidity raw water often have low horizontal velocity in the water intake rectification area, and the undissolved particles in the raw water are easy to deposit and form silt, which increases the workload of the water intake structures. At the same time, the sediment due to Anoxic fermentation at the bottom of the water will also have a negative impact on the water quality of the water intake. This production problem has become a major produc...
