A dosing device for sludge treatment and a dosing method thereof

Abstract

The invention discloses a dosing device for sludge treatment and a dosing method of the dosing device. The dosing device is characterized in that automatic dispensing units are arranged on a base, flocculation mixing tanks are arranged in a leveling board, an adjusting unit is arranged at the top of each support rod, pressing plates are arranged on the adjusting units, a dosing plate is arranged at the top of each automatic dispensing unit, side plates are arranged on two sides of the dosing plate, and the pressing plates press the side plates. The dosing method includes a), selecting sludge treatment agents in groups; b), blending the agents in the flocculation mixing tanks; c), mounting the flocculation mixing tanks; d), cleaning the automatic dispensing units; e), adjusting and mounting the automatic dispensing units; f), mounting the dosing plates; g), throwing sludge fluid to the automatic dispensing units; h), releasing the sludge treatment agents gradually; i), feeding the sludge fluid into the flocculation mixing tanks; j), drying the sludge fluid and performing sampling for analysis. By the arrangement, sampling comparison on sludge treatment is performed by using different sludge treatment agent ingredients, and the sludge treatment agents can be optimized.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a dosing device and a dosing method for sludge treatment. Background technique [0002] Sludge is one of the main by-products after sewage treatment, accounting for about 0.3%-0.5% (volume) or 1%-2% (quality) of the sewage treatment volume. With the development of industrial and agricultural production and the continuous construction of sewage treatment plants around , my country's industrial and domestic sewage treatment volume is increasing rapidly, and more sludge is bound to be produced. The composition of sludge is very complex. In addition to a large amount of water, it also contains a large amount of organic matter, refractory organic matter, various trace elements, pathogenic microorganisms, parasite eggs and heavy metals. If it is not treated and discharged randomly, it will cause secondary pollution to the environment, and the difficulty of re-treat...

Problems solved by technology

In this process, corresponding chemicals need to be added, but at present, all the chemicals are mixed together to treat the sludge. The specific effect of the specific ingredients on the sludge treatment cannot be known, and the choice of chemicals cannot be further optimized.
