Problems solved by technology

However, due to problems such as crystallization and bonding of polyferric sulfate in the pipeline, it is easy to cause pipeline blockage, which seriously affects the treatment effect and efficiency of sewage.
Sewage plants have repeatedly blocked pipes or even burst pipes due to the crystallization of polyferric sulfate
The dosage of polyferric sulfate in chemical phosphorus removal directly affects the phosphorus removal effect of water treatment. Manual dosage cannot adjust the dosage of polyferric sulfate in real time according to the water quality and quantity, and cannot achieve the ideal phosphorus removal effect.
[0003] Insufficient existing technology: small dosage, low flow rate, polyferric sulfate is easy to crystallize and block the pipeline, or even burst the pipeline

Abstract

The invention discloses a dosing system, which is characterized by including a dosing pump, a dosing tank, a dosing device and an aeration tank, the dosing device comprises an inverted U type siphon, a floating ball and a bracket, wherein the bracket comprises a longitudinal rod and at least one lateral plate, the longitudinal rod is vertically fixed on the dosing tank, the middle part of each lateral plate is fixedly arranged on the longitudinal rod, two ends of each lateral plate are provided with sliding chutes, two longitudinal pipes of the inverted U type siphon respectively downward penetrate into the sliding chutes, the floating ball is fixed on the end of a short longitudinal pipe of the inverted U type siphon, the floating ball is located in the dosing tank, and a long longitudinal pipe of the inverted U type siphon is located just above the aeration tank. The dosing system can maintain a certain flow velocity, can uninterruptedly dose to the aeration tank, and can be regularly swashed, polymeric ferric sulfate is not easy to crystallize in the pipe, blockage is not easy to cause, and the dosing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of dosing in sewage pools, and in particular relates to a dosing system. Background technique [0002] The sewage plant is equipped with a dosing room. At this stage, phosphorus removal is mainly done by diluting polyferric sulfate in the dosing room and adding it to the end of the aeration tank through a pipeline with a metering pump and an acid-resistant pump. After chemical precipitation and flocculation, phosphorus removal is achieved. the goal of. However, due to problems such as crystallization and bonding of polyferric sulfate in the pipeline, it is easy to cause pipeline blockage, which seriously affects the treatment effect and efficiency of sewage. Pipeline blockages and even pipe bursts have occurred many times in sewage plants due to the crystallization of polyferric sulfate. The dosage of polymerized ferric sulfate in chemical phosphorus removal directly affects the phosphorus removal effect o...
