Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a hierarchical sewage treatment device. Background Art

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, and catering. Due to the different sources of sewage, sewage contains different harmful substances. In order to improve the convenience of sewage treatment, graded sewage treatment equipment is usually used to efficiently treat various harmful substances in sewage in steps, but it still has the following disadvantages in actual use:

[0003] The utility model with the publication number CN205061783U discloses a hierarchical sewage treatment device, wherein a stirring tank body is provided in the stirring device, a stirring shaft is provided inside the stirring tank body, a stirring motor is connected to the part of the stirring shaft extending out of the stirring tank body, a dosing box is provided on the stirring tank body on the left side of the stirring motor, a dosing motor is provided at the bottom of the dosing box, in addition, a water pumping port is provided at the bottom of the stirring tank body, and the water pumping port is connected to the top of the electric field water treatment device through a third water pipe; the bottom of the electric field water treatment device is connected to the clean water storage tank through a connecting water pipe, and a clean water outlet is provided at the bottom of one side of the clean water storage tank. When sewage is treated, it is usually necessary to fully mix the sewage and the agent, but whether it is a solid agent or a liquid agent, it is usually difficult to quickly and evenly mix with the sewage, especially for sewage treatment in small and medium-sized factories. In order to adapt to the production environment, the volume of the sewage treatment equipment is usually small, and it is difficult to store a large amount of sewage at the same time. In order to avoid the direct discharge of sewage that does not meet the discharge standard, the only option is to delay the generation speed of sewage from the source, which affects production;

[0004] When sewage reacts with chemicals, some chemicals and sewage may produce harmful gases, and some sewage will evaporate into waste gas when the sewage is left standing or stirred. However, sewage treatment equipment usually does not have a gas treatment structure, which results in the need for subsequent waste gas treatment, reducing sewage treatment efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a hierarchical sewage treatment equipment, which solves the problem that when sewage is treated in small and medium-sized production plants, the small-volume treatment equipment is difficult to store a large amount of sewage at the same time, and it is difficult to fully treat harmful substances in the sewage in a short time. When the sewage is stirred or left to stand, part of the sewage will evaporate, and the sewage treatment equipment usually does not have a gas treatment structure, resulting in the need for subsequent waste gas treatment.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The solid particles in the sewage can be filtered through the filter mesh tube. After the sewage is initially filtered, the sewage can be pumped into the first spray pipe through the liquid pump and sprayed out through the first spray pipe in atomization. At the same time, the liquid medicine is sprayed out through the second spray pipe in atomization, so that the atomized medicine and the sewage are fully in contact, so as to ensure the sewage treatment efficiency, avoid the need for sewage to stand or stir in the container, so that the sewage is always in a flowing state, does not occupy the space in the treatment equipment, and thus can reduce the volume of the treatment equipment, making the treatment equipment more suitable for small and medium-sized production plants. After the sewage contacts the liquid medicine in the spray box, when the formed droplets are large and settle to the bottom of the spray box, they enter the filter element through the liquid inlet pipe, and when the droplets are small, the gas and small droplets in the spray box can be pumped into the filter element through the air pump, and the waste gas and waste liquid are filtered and treated simultaneously through the filter element, so as to avoid the waste gas accumulation in the spray box and the need for subsequent treatment, thereby improving the treatment efficiency of the treatment equipment for sewage.

When it is monitored that no more sewage enters the filter box, the lifting cylinder is controlled to drive the scraper to move up and down, which can scrape off the solid particles blocking the filter network pipe and ensure the filtration efficiency.

[0013] Furthermore, a second sealing cover is fixedly connected to the top of the spray box, a plurality of the second spray pipes are connected to a liquid pipe at the bottom, a liquid pump is connected to a liquid extraction pipe at one end, a connecting pipe is connected to the top of the liquid pump, the connecting pipe is connected to the top of the second sealing cover, and the first spray pipe is connected to the other end of the connecting pipe relative to the liquid pump;

[0014] The filtered sewage can be pumped into the first spray pipe through the liquid pump, and sprayed in the spray box through the first spray pipe in atomized form. At the same time, the medicine liquid is continuously pumped into the liquid pipe, and sprayed in the spray box through the second spray pipe in atomized form, so that the atomized medicine and the sewage are fully in contact, thereby ensuring the sewage treatment efficiency, avoiding the need for the sewage to stand or stir in the container, and keeping the sewage in a flowing state at all times, not occupying the space in the treatment equipment, thereby reducing the volume of the treatment equipment, and making the treatment equipment more suitable for small and medium-sized production plants.

[0016] After the sewage comes into contact with the liquid medicine in the spray box, when the formed droplets are large and settle to the bottom of the spray box, the sewage flows into the purification box through the liquid inlet pipe. When the droplets are small, the air in the spray box is evacuated through the air pump to pump the gas and small droplets into the purification box, avoiding the accumulation of waste gas in the spray box and requiring subsequent treatment, thereby improving the treatment efficiency of the treatment equipment for sewage.

[0017] Further, a liquid inlet pipe is inserted through the bottom of the outer peripheral surface of the filter element, and the liquid inlet pipe is inserted through the outer peripheral surface of the purification box. The other end of the liquid inlet pipe relative to the filter element is inserted through the bottom of the outer peripheral surface of the spray box, and a liquid discharge pipe is welded through the bottom of the outer peripheral surface of the purification box. A first exhaust pipe is welded through the outer peripheral surface of the purification box, and a second exhaust pipe is welded through the other end of the first exhaust pipe.

[0018] After the sewage and waste gas are purified by the filter element, the water is discharged through the drain pipe, and the gas enters the second exhaust pipe through the first exhaust pipe. The gas is cooled by the semiconductor refrigeration component, so that the vaporized medicine in the gas is condensed and flows into the drain pipe under the action of gravity.

[0019] The utility model has the following beneficial effects:

[0020] The utility model solves the problem that when sewage is treated, it is usually necessary to fully mix sewage and chemicals, but no matter it is a solid chemical or a liquid chemical, it is usually difficult to quickly and evenly mix with sewage, especially in small and medium-sized factories. In order to adapt to the production environment, the volume of sewage treatment equipment is usually small, and it is difficult to store a large amount of sewage at the same time. In order to avoid direct discharge of sewage that does not meet the discharge standard, it is only possible to delay the generation speed of sewage from the source, which affects the production. After the sewage is filtered, the sewage is pumped into the first spray pipe by a liquid pump, and sprayed into the spray box through the first spray pipe in an atomized form. A large amount of chemical liquid is sprayed into the spray box through the second spray pipe, so that the atomized sewage and the atomized chemical liquid are fully in contact and react, thereby ensuring the treatment efficiency of the sewage, avoiding the need for sewage to stand or stir in the container, and keeping the sewage in a flowing state at all times, without occupying the space in the treatment equipment, thereby reducing the volume of the treatment equipment and making the treatment equipment more suitable for small and medium-sized production plants.

[0021] The utility model solves the problem that when sewage reacts with chemicals, harmful gases may be generated when some chemicals react with sewage, and when sewage is left standing or stirred, some sewage evaporates and becomes waste gas, while sewage treatment equipment usually does not have a gas treatment structure, resulting in the need for subsequent treatment of waste gas, thereby reducing sewage treatment efficiency. After the sewage contacts the chemical solution in the spray box, when the formed droplets are large and settle to the bottom of the spray box, they enter the purification box through the liquid inlet pipe for purification treatment, and when the droplets are small, the gas and small droplets in the spray box are pumped into the purification box for purification treatment through an air pump, thereby avoiding the waste gas from accumulating in the spray box and requiring subsequent treatment, thereby improving the sewage treatment efficiency of the treatment equipment.
