Problems solved by technology

[0005] However, the existing high-efficiency clarifiers for water purification often have poor sedimentation effects, and the simple discharge of sludge does not serve as a "helper" for flocculation, thereby reducing the reduction of chemical agents

Embodiment

[0022] Embodiment: a kind of black and smelly river course pretreatment pond, as figure 1 As shown, it includes reaction zone 1 and clarification zone 2. Reaction zone 1 includes mixing reaction zone 11 and plug flow reaction zone 12. Mixing reaction zone 11 includes water inlet pipe 111 and slow flow cylinder 112. The lower end of slow flow cylinder 112 is connected to the inlet. The water pipe 111 is connected, the slow flow cylinder 112 is pierced with an agitator 113 , and the upper end of the slow flow cylinder 112 is connected with the push flow reaction zone 12 .

[0023] Clarification zone 2 comprises inlet 21, inclined tube sedimentation zone 22 and concentration zone 23, plug flow reaction zone 12 is communicated with inlet 21, and inclined tube precipitation zone 22 is positioned at the upper end of clarification zone 2, and concentration zone 23 is positioned at the lower end of clarification zone 2, concentrates The outlet at the bottom of the zone 23 is connected...

Abstract

The invention discloses a black and odorous river course pretreatment pool, which relates to the technical field of sewage treatment and includes a reaction zone and a clarification zone. The reaction zone includes a mixing reaction zone and a push flow reaction zone. Inclined tube sedimentation zone and concentration zone, the plug flow reaction zone is connected to the inlet, the inclined tube sedimentation zone is located at the upper end of the clarification zone, the concentration zone is located at the lower end of the clarification zone, there is a mud bucket in the concentration zone, and it also includes a sludge circulation system and a sewage system The sludge circulation system includes a sludge circulation pipeline and a sludge circulation pump. One end of the sludge circulation pipeline is connected to the mud bucket, and the other end of the sludge circulation pipeline is connected to the mud inlet pipe. The first switch valve is arranged on the sludge circulation pipeline. The sewage system includes a sewage pipeline and The sewage pump, the sewage pipeline communicates with the mud hopper, and the sewage pipeline is provided with a second on-off valve. The invention has the advantage that the sludge discharged from the mud hopper can be selectively recycled, thereby improving the sedimentation effect of the black and odorous river course pretreatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a black and odorous river course pretreatment pool. Background technique [0002] Clarification method is one of the most basic methods in water treatment. It is a process that uses the density difference between suspended particles in water and water to produce sinking under the action of gravity to achieve solid-liquid separation. According to the nature of sewage and the degree of treatment required, the sedimentation treatment process can be a process in the entire water treatment process, or it can be used as the only treatment method. [0003] The medium used to trap and separate impurity particles in the clarifier is suspended sludge. In the clarification tank, the sediment is lifted up and placed in a uniformly distributed suspension state, forming a high-concentration stable active sludge layer in the tank, and the suspended solids concentration of this layer ...
