Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of dredging the bottom of the pool body in the prior art, the waste water in the pool body is drained, and after the sludge at the bottom of the pool body is exposed to the surface, water pumps or manual dredging are used, and the dredging efficiency is low , needs to be interrupted for a long time, which seriously affects the problem of wastewater treatment efficiency. A papermaking wastewater treatment process proposed by the present invention

Embodiment approach

[0033] As an embodiment of the present invention, the top of the pool body 1 is provided with an unwinding roller 2 at a position corresponding to the storage chamber 13, and the end of the steel rope 16 close to the sliding rod 12 is wrapped around the roller blind 14 and then wound around the outer circumference of the unwinding roller 2. Rewinding the steel rope 16 by the unwinding roller 2 drives the rolling curtain 14 to be retracted, increasing the cleaning efficiency of the pool body 1. The rotation of the unwinding roller 2 drives the steel rope 16 to move closer to the storage chamber 13, because the steel rope 16 After bypassing the coiled roller blind 14, it is wound on the unwinding roller 2. The friction force between the steel rope 16 and the roller blind 14 drives the roller blind 14 to wind up quickly, which increases the resetting efficiency of the roller blind 14 and further reduces the cleaning of silt Time, to ensure that the tank body 1 returns to the best s...

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a papermaking wastewater treatment process. A wastewater treatment pool used in the process comprisesa pool body; sliding grooves are formed in the positions, close to the bottom, of the two sides of the pool body, sliding rods are slidably connected in the sliding grooves, a storage chamber is formed in one side of the pool body, wound roller shutters are arranged in the storage chamber, and one end of the roller shutters extends out of the storage chamber and is fixedly connected with the sliding rods. A winch is rotationally connected to the side, away from the storage chamber, of the top of the pond body through a support, wound with a steel rope and driven by a motor; an L-shaped wire slot is formed in the pool body at the bottom of the winch; the steel rope penetrates through the wire slot after being led out of the winch and is connected with the sliding rods; a suction pipe for sucking sludge is arranged at the bottom of the pool body and is communicated with the water pump; the roller shutters are pulled out through the steel rope to shield sludge at the bottom of the pool body, water pollution on the upper portion of the pool body is reduced, and sediment cleaning efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of wastewater treatment, and specifically is a papermaking wastewater treatment process. Background technique [0002] The production wastewater of electroplating, leather, chemical, papermaking and other industries is generally complex and has a wide variety of pollutants. It usually has the characteristics of high CODCr, high BOD5, high SS concentration, high NH3-N concentration, and high chroma, which is the most difficult to treat One of the industrial wastewater. Generally, traditional physicochemical and biochemical treatment processes are used for treatment, which can only remove SS, COD and other substances in wastewater. The removal effect of other pollutants is not good. For example, the ammonia nitrogen concentration is generally above 200mg / L, which cannot meet the sewage discharge standard. [0003] The Chinese invention patent with the publication number CN105712571A and the publication date of 2016....
