Chemical dissolving tank for sewage treatment and its dosing control method

Abstract

The invention discloses a medicament dissolution tank for sewage treatment and a medicament adding control method thereof. The dissolution tank comprises a tank body, a control system and a quantitative medicament feeding device; the quantitative medicament feeding device comprises a medicament receiving chamber, a main accommodating chamber and N replenishment accommodating chambers, wherein N islarger than or equal to 1; N+1 medicament distribution pipes, each of which is connected with one corresponding accommodating chamber, are arranged below the medicament receiving chamber; a movable door switch is arranged at the connection end of each medicament distribution pipe and the corresponding accommodating chamber; a reset baffle plate is arranged on the bottom surface of each accommodating chamber; a first weighing sensor is arranged on each reset baffle plate; a liquid level gauge is arranged in the tank body; and the liquid level gauge, the movable door switches, the first weighing sensors, the reset baffle plates and the control system are electrically connected with one another. The medicament dissolution tank is reasonable in design, automatic in control and high in controlaccuracy of medicament dosing quantity.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a chemical dissolving tank for sewage treatment and a method for controlling the dosing thereof. Background technique [0002] At present, when people treat sewage, it is necessary to add various chemical agents to the sewage as coagulation, flocculation, and coagulant aids for disinfection and sterilization to achieve the purpose of water purification; for some granular solid chemical agents (later Dissolution is generally carried out first, and the concentration of dissolution can be controlled, and then put into the reaction tank according to a certain ratio for coagulation or flocculation or coagulation aid. If the dosing amount of the chemical is not properly controlled during the dissolution process, it will affect the treatment effect of the wastewater in the subsequent reaction tank, and if the dosage is too much, the cost of using the relevant chemical agent will be incre...
