Sewage treatment apparatus

Abstract

The invention discloses a sewage treatment apparatus, which comprises a valve, a steam pipeline, a spraying head, a flue gas discharge pipe, a cover, a furnace, an evaporation panel, gas inlet holes,a stove head, an annular support, a total pipe and a water pump, wherein the opening on the top portion of the furnace is fixedly connected to the cover through a flange structure, the evaporation panel is arranged inside the furnace, and is tapered, the edge of the evaporation panel overlaps on the annular support welded on the inner wall of the furnace, the stove head for heating is arranged below the evaporation panel, and is connected to a fuel system by a pipeline, a plurality of the gas inlet holes for supplying air for combustion are arranged at the bottom portion of the furnace, and one end of the flue gas discharge pipe is welded at the through hole position on the middle portion of the evaporation panel. According to the present invention, the water can be rapidly sprayed to thehigh-temperature evaporation panel by the spraying head so as to rapidly produce high-temperature steam while the water is changed into steam, and the internal particles and inorganic substances are precipitated, such that the efficient sewage treatment can be achieved without the adding of the compound.

Description

technical field [0001] The invention relates to the field of sewage treatment and regeneration, in particular to a sewage treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] In actual life, sewage contains a large amount of organic substances such as carbohydrates, proteins, amino acids, fats, etc., as well as inorganic substances such as heavy metals and inorganic salts. Traditional sewage treatment methods mostly use equipment for sedimentation treatment, and then use chemical substances Neutralization, flocculation and other processes are carried out, but althou...

Problems solved by technology

[0003] In actual life, sewage contains a large amount of organic substances such as carbohydrates, proteins, amino acids, fats, etc., as well as inorganic substances such as heavy metals and inorganic salts. Traditional sewage treatment methods mostly use equipment for sedimentation treatment, and then use chemical substances Neutralization, flocculation and other processes are carried out, but although the treatment method of this additive substance can obtain discharge water that meets the standard, the overall content of the additive is still increased, so a large amount of waste sediment is generated

[0004] The existing treatment methods are not effective in treating heavy metals in water
