Problems solved by technology

On the other hand, if the water temperature is too high, the flocs formed will be fine, and the moisture content of the sludge will increase, making it difficult to handle.
Therefore, too high or too low water temperature is not good for flocculation.

Embodiment Construction

[0031] like figure 1 As shown, a precise feeding device in the sewage treatment process, including: reaction tank 1, propeller, dosing machine 3, liquid level gauge 4, dosing machine 5, flow valve, flow meter, temperature sensor, PH value sensor, DO Sensors, suspended solid sensors, conductivity sensors, computer control systems;

[0032] The water inlet pipe 11 of the reaction tank 1 is arranged on the upper part of the water inlet side of the reaction tank, the outlet pipe 12 of the reaction tank 1 is arranged on the upper part of the water outlet side of the reaction tank 1, and the first baffle 13 and the second baffle are arranged in the reaction tank 1. The baffle 14, the first baffle 13 and the second baffle 14 divide the body of the reaction tank 1 into three sections from the water inlet side to the water outlet side, and the upper edge of the first baffle 13 is flush with the top of the pool body There is a gap of 150-250 mm between the lower edge of the first baffl...

Abstract

An accurate feeding device in sewage treatment processes comprises a reaction tank, propellers, a medicine feeding machine, a liquid level meter, a medicine supplementing machine, a flow valve, a flow meter, a temperature sensor, a PH value sensor, a DO sensor, a suspended solid sensor, a conductivity sensor and a computer control system. Blades of the propeller of a front section tank body are located on the upper portion of a tank body, blades of the propeller of a back section tank body are located at the bottom of the tank body, the medicine supplementing machine is erected above the liquid level of the back section tank body, medicine liquid is contained in a storage box of the medicine supplementing machine, a liquid outlet of the storage box is connected with a medicine applying pipe through a pump, a pipe opening of the medicine applying pipe stretches into the position under the propeller of the back section tank body, and the pipe opening of the medicine applying pipe is provided with a one-way valve to prevent sewage in the tank body from flowing backwards. The invention further provides an accurate feeding method in the sewage treatment processes. By utilizing the method that medicine feeding is firstly performed and medicine supplementing is secondly performed and synthesizing water temperature and environment factors, accurate medicine feeding is achieved, the removal rate of pollutants is guaranteed, the medicine applying amount is saved, and the cost is saved.

Description

Technical field: [0001] The invention relates to the technical field of sewage treatment, in particular to a precise feeding method and device in a sewage treatment process. Background technique: [0002] In the sewage treatment process, it is necessary to add coagulants, flocculants, coagulants, etc. to the sewage for physical and chemical reactions to form sediments. Studies have shown that the temperature has a significant effect on the reaction and flocculation. In general, when the water temperature is 27-30 °C, the impact on SS and BOD 5 , COD, NH 3 The removal rates of -N and TP are optimal, and the removal rates are significantly lower when the water temperature is lower than 20°C. [0003] For activated sludge treatment of sewage, the particle size, surface charge, density and microbial components of activated sludge are greatly affected by the operating temperature, which will also affect the dewatering performance and settling properties of activated sludge. St...
