Recycled water replenishing port residual chlorine content monitoring and filtering device and dechlorination method

Abstract

The invention discloses a recycled water replenishing port residual chlorine content monitoring and filtering device and a dechlorination method. The recycled water replenishing port residual chlorine content monitoring and filtering device comprises a filtering unit, monitoring units and an air supply unit, the filtering unit is axially inserted and fixed into a drainage pipe of a recycled water replenishing port, the monitoring units are fixedly arranged at the two ends of the filtering unit, and one end of the filtering unit communicates with the air supply unit; the filtering unit comprises a cylindrical shell, cambered surface inclined plates and an aeration cavity, a plurality of cambered surface inclined plates with holes are obliquely and fixedly connected to the interior of the cylindrical shell in parallel at intervals, the aeration cavity communicating with the air supply unit and an inner cavity of the cylindrical shell is axially and fixedly arranged on the inner wall of the lower part of the cylindrical shell, the inner cavity of the cylindrical shell is divided into a plurality of inclined filtering cavities by the cambered surface inclined plates, and the filtering cavities are partially filled with filtering particles. The device can be conveniently connected with a pipeline, adopts double means of aeration and adsorption to filter residual chlorine in a water body, avoids blockage of a water replenishing port, and is suitable for being used in a water regeneration plant.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a residual chlorine content monitoring filter device and a chlorine removal method of a regenerated water replenishment port. Background technique [0002] The chlorine disinfection method is easy to operate, low in cost, mature in technology, good in disinfection effect, and easy to measure the residual chlorine concentration. Chlorine disinfection has been the most economical, effective and widely used water disinfection method since its inception. Under normal circumstances, the reclaimed water plant detects the content of total chlorine and free residual chlorine at the outlet of the clean water tank. If it is lower than the effluent standard, it will perform post-chlorine supplementation; if the residual chlorine content at the end of the pipe network is greater than or equal to 0.2mg / L, it should be reduced. Chlorine dosage. [0003] However, in reality, the qualit...

Problems solved by technology

[0007] 3. At present, there are no targeted facilities and equipment and suitable methods on the market to solve the problem of high residual chlorine in the water outlet of reclaimed water plants

[0010] After analysis, the residual chlorine control device in the above-mentioned published patent is quite different from the present application in the structure and function of residual chlorine detection and filtration, so it does not affect the novelty of the present application
