Integral domestic sewage treatment equipment

Abstract

The invention belongs to the field of sewage treatment equipment, and discloses integral domestic sewage treatment equipment. The equipment comprises a tank body and also comprises an equipment zone, wherein the interior of the tank body is divided into a feed water hydrolyzing area, an aerobic area and a settling area. The equipment is characterized in that the equipment zone is arranged outside the tank body, the feed water hydrolyzing area comprises a water passage circling the interior of the tank body, the aerobic area and the settling area are arranged at the water pipeline, a submersible sewage pump and an aerating apparatus are arranged at the middle bottom part of the aerobic area, and a convey port of the submersible sewage pump is communicated with the water feed end of the water passage through a pipeline. The structural design of the tank body is more scientific and reasonable, so that the equipment has a better sewage treatment effect, is more efficient, saves more energy, and is simple and convenient to maintain by adopting the tank body of the same volume. Furthermore, the invention also provides a use method of the integral domestic sewage treatment equipment, which is characterized by comprising a step of treating the sewage with the integral domestic sewage treatment equipment.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, and specifically relates to an integrated domestic sewage treatment equipment, and at the same time, the invention also relates to a method for using the integrated domestic sewage treatment equipment. Background technique [0002] Domestic sewage includes all kinds of washing water, sewage and feces in urban life. Most of them are non-toxic inorganic salts with relatively fixed components. They mainly contain carbohydrates, proteins, amino acids, fats and other organic substances, which are more suitable for bacteria and viruses It grows and has a certain fertilizer effect, which can be used to irrigate farmland. At the same time, the nitrogen, phosphorus and other plant nutrients in domestic sewage contain a lot of nutrients, which can easily cause eutrophication of the water body and is one of the main pollution sources of the water body. Rivers and lakes, so as to overcome the wat...

Problems solved by technology

[0006] However, the technical solutions of the above-mentioned improved integrated membrane sewage regenerator and sewage treatment and reuse integrated device all have the following deficiencies: the inside of the tank runs from left to right along the length of the tank (see its attached figure 1 ), which is divided into four sections with facultative zone (same as hydrolytic acidification anaerobic reaction tank), aerobic and membrane filtration zone (same as aeration tank and membrane filter tank), equipment zone, and clear water zone (same as regenerative tank) The structure, in which the equipment area is set in the tank area, occupies the internal space of the tank, reduces the space for sewage treatment in the tank (reduces the sewage treatment capacity), and causes a waste of tank space

[0008] However, the above-mentioned integrated sewage treatment tank has the disadvantage that in this technical solution, a grille filter room is provided at the front end of the tank body (at the water inlet end), so that it can remove large particles such as suspended solids in sewage Impurities, etc. are caught by nets, but after a certain period of time, it is necessary to remove the above-mentioned suspended matter and other large particles of impurities from the grid filter by opening the observation port on the top of the tank to avoid clogging and subsequent water treatment. make an impact

[0010] 1. The interior space of the tank is unreasonable, which not only affects the sewage treatment effect, but also limits the improvement of sewage treatment efficiency

[0011] 2. The staff in the tank need to clean and maintain it regularly, which increases the maintenance workload of the staff

[0012] 3. After using biofilm to filter sewage, water pumps are used to lift the water to the clean water area. This process requires the use of electric energy, which increases the cost of use
