Abstract

The invention discloses a waterworks primary sedimentation tower, which comprises a primary sedimentation tower and a water taking device. The water taking device comprises a filtration room, a water storage room and a fixed support. The front end of the filtration room is provided with a water inlet, and a filter screen is arranged inside the filtration room. A filtration water pipe is connected between the filtration room and the water storage room. The bottom of the water storage room is provided with the fixed support. The water storage room is connected to the primary sedimentation tower through a water inlet pipe. The primary sedimentation tower comprises inner and outer towers and a sludge discharge passageway between the inner and outer towers. The bottom of the inner tower is connected to a water inlet pipe, and the top of the inner tower is connected to a water outlet pipe. At least two baffle plates which are tilted upwards are arranged from top to bottom inside the inner tower in a crossed manner. The lower broadside of each baffle plate is fixedly connected to the tower wall of the inner tower. By arranging the water taking device at the water taking end of a water source, floating substances and silt in water can be effectively intercepted. After raw water flows through the primary sedimentation tower, other large-granular impurities in water can be further settled on the baffle plates. Then, the raw water has fundamentally met water quality requirement of waterworks water inlet ends.

The beneficial effect adopting the technical program is because the water intaking end at water source is provided with water fetching device, effectively can remove the floating thing in water and silt, when now former water flows through primary settling tower again, in water, other large granular impurity to be deposited in further on deflection plate and to enter in mud discharging passage, now the turbidity of former water reduces greatly, substantially can reach the water quality requirement of water factory's water inlet end.

As preferably: be provided with mud discharging pipe at the bottom of the tower of above-mentioned outer tower, described mud discharging pipe is provided with mud discharging control valve.The beneficial effect of this scheme is adopted to be that the mud be deposited at the bottom of outer tower tower is regularly discharged by mud discharging pipe.

Above-mentioned deflection plate is 20-30, is evenly distributed at the bottom of the tower of described interior tower and between tower top.Adopt the beneficial effect of this scheme to be that deflection plate density is arranged rationally, shorten the distance of impurity sedimentation, be conducive to the sedimentation accelerating impurity.

The above-mentioned mud discharging control valve opening time is spaced apart 20-24 hour.Adopt the beneficial effect of this scheme to be regularly got rid of by the mud of deposition, avoid mud overheap, affect sedimentation effect.

Sludge-tank is provided with below above-mentioned outer tower.Adopt the beneficial effect of this scheme be deposition mud concentrate be emitted in sludge-tank, facilitate workman concentrate cleaning.

Above-mentioned interior top of tower is provided with observation window.The beneficial effect of this scheme is adopted to be fast check purifier inner case by observation window.

Beneficial effect:

Adopting the invention has the beneficial effects as follows because the water intaking end at water source is provided with water fetching device, effectively can tackle the floating thing in water and silt, when former water flows through primary settling tower again, in water, other large granular impurity to be deposited in further on deflection plate and to enter in mud discharging passage, now the turbidity of former water reduces greatly, substantially, the water quality requirement of water factory's water inlet end can be reached, through the primary filter of this equipment, the dosage of water factory processed medicament and chlorine can be reduced, reduce aluminium salt and DBPs content in the rear water of filter, whole device security is reliable, filtration result is good.
