Problems solved by technology

[0003] The sludge produced by the water treatment system has a high water content and a large volume, which is inconvenient for transportation, treatment or disposal. In order to reduce the number of sludge dewatering machines, the treatment quality and treatment efficiency of existing technology equipment are also a city or modernization factory logo

Embodiment Construction

[0049] After the research and analysis of the applicant, most of the equipment in the whole sewage treatment process can realize mechanized and automatic operation with high accuracy and high efficiency. However, the manual dosing part has always been the lagging point of the modern sewage plant, and the material powder is added during the dosing process. It often sticks to the wall of the dosing hopper, causing the powder to return to moisture, causing the water inlet to be blocked, causing the stop of dosing, which not only causes waste of powder, but also increases labor costs to dredge, and the efficiency is low. Based on these problems, the applicant proposed a fully automatic dosing device for sewage treatment, the specific scheme is as follows.

[0050]As shown in the drawings, a fully automatic dosing device for sewage treatment includes a base frame 1, a reaction column 2, a dosing unit 3, a housing 301, a cavity 3011, an inner wall 3012, an outer wall 3013, a resistan...

Abstract

The invention discloses a full-automatic dosing device for sewage treatment and a method thereof, and belongs to the technical field of water treatment. A resistance wire is added into the inner cavity of a dosing hopper; the dryness of powder is ensured; meanwhile, a stirring device is arranged at the top of a medicament dissolving tank; the phenomena that medicaments are not easy to dissolve anddust is generated are avoided; the screw pitch of a screw passing through a screw rod is gradually reduced from left to right; the powder entering screws is pressed more and more tightly; the pressure loss of the system is reduced; the leakage of compressed air in a pipeline of a conveying device is prevented; meanwhile, a water supply valve is opened before feeding; when a gas-material mixture reaches the outlet of a pneumatic conveying pipeline and is sprayed by a water column, separation of materials and gas is achieved, powder is taken away by water to enter the medicament dissolving tank, water is supplied in a spraying mode to guarantee that the powder can be evenly mixed with water in time after leaving the conveying device, dust is avoided, and dissolution is facilitated. Waste ofpowder is reduced, and finished products are saved.

Description

technical field [0001] The invention relates to a fully automatic dosing device for sewage treatment, in particular to a fully automatic dosing device for sewage treatment and a working method thereof. Background technique [0002] Urban wastewater refers to the mixture of domestic sewage, industrial wastewater and atmospheric precipitation in the city. Its nature varies with city scale, climatic conditions, drainage system and other factors, especially the number and nature of industries in the city, and the degree of pretreatment of industrial wastewater. When there are certain internal control measures for special pollutants discharged by industries, such as heavy metals, acids, alkalis, toxic substances, oils, etc., the properties of general urban wastewater are similar. The most serious water pollution caused by urban wastewater is organic pollution. The BODS and COD in the water body exceed the standard and contain many organic substances that are difficult to be biode...
