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 water plants; for the freezing problem of water intake projects, most of them only use manual regular cleaning at present, and the management and maintenance workload is huge

Abstract

The invention discloses a low-temperature high-turbidity water taking desilting anti-freeze system and method. The low-temperature high-turbidity water taking desilting anti-freeze system comprises a water inlet rectifier area, a water suction well and a pipeline system; the water inlet rectifier area is connected with a water taking body; the connecting position is provided with a partition gate; a partition wall is arranged in the water inlet rectifier area along each side of the direction of the water flow; the inner wall surface of each partition wall is provided with a concrete lobe which is used for preventing freezing of the water surface; a suction dredge is arranged in the water inlet rectifier area; the water suction well is connected with the water inlet rectifier area and comprises two side walls; the inner wall surface of each side wall is provided with a concrete lobe; the pipeline system is connected with the water suction well and used for conveying the water in the water suction well to a water treatment plant. According to the low-temperature high-turbidity water taking desilting anti-freeze system and method, the low-temperature anti-freeze function is achieved, the sludge discharge is performed on a low-speed water inlet channel in which the deposition is easy to produce regularly, meanwhile the function of raw water scouring and silting is combined, and accordingly the water and energy conservation, the reduction of the water sediment and management simplification are truly implemented and the stability of the quality of the raw water is ensured.

Description

technical field [0001] The invention relates to the field of high-turbidity water intake and cleaning, in particular to a low-temperature high-turbidity water intake dredging antifreeze 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 quality of water intake. This production problem has become a ...
