Sewage treatment equipment

Abstract

The present invention relates to a sewage treatment equipment. In the interior of sewate treatment sump, there are natural microbial pool and sewage treatment equipment of aeration installation. Its aerating pipe is connected with an external air compressor capable of feeding air so as to fully stir the seage being in the treatment sump, and increase its air-transferring efficiency and mass-produce clean water to obtain the effect of eliminating organic sludge and cleaning sewage. The aerating pipe of said equipment is movably mouted at a preset position with a certain height from treatment sump bottom, and all the water intake pipes and water discharge pipes as well as water inlets and water outlets of all the treatment sumps are in same level height state.

Description

(1) Technical field: [0001] The invention relates to a sewage treatment device that can eliminate organic matter and organic biological sludge in a sewage treatment tank to achieve the effect of sewage purification, and can make the sewage in the sewage tank produce natural convection without any power equipment The drainage effect is extremely valuable for industrial use and belongs to the sewage treatment device. (two) background technology: [0002] At present, the downstream sewage treatment methods commonly used in the food manufacturing industry, catering industry, animal husbandry industry, or communities are all based on the "over-aeration method", which uses air to activate the aerobic bacteria in the sewage. However, this treatment method But it will cause secondary organic sludge to be produced, which will cause serious pollution to the environment. [0003] Furthermore, general domestic wastewater and industrial wastewater contain proteins, fats, carbohydrates a...

Problems solved by technology

[0015] 1. Because its aeration is at the bottom of the tank, the organic sludge in the sewage in the tank will form a regional concentration, resulting in sludge precipitation, and the organic sludge in the sewage tank cannot be completely eliminated. Afterwards, it will be cleaned up separately, which is time-consuming, labor-intensive and uneconomical. It will also produce stench and seriously affect environmental sanitation.

[0016] 2. Since the sludge sedimentation treatment method is adopted in each water tank, the positions of the water inlets and outlets must not be at the same water level, and the pump must be used to drive the water flow and pumping force, which often results in the construction being restricted by the terrain. But construction is impossible or difficult, not only the cost of construction equipment is very high and uneconomical, but also the failure rate is high, and maintenance is difficult. Moreover, professional personnel are required to deal with it. In case of power failure, the survival of microorganisms will be quickly destroyed.

[0017] 3. The aeration pipes in each water tank are fixed on the bottom of the water tank. Once the damaged aeration pipe is to be replaced, the entire sewage treatment system must be stopped first, and the sewage in the water tank must be discharged before personnel can enter the water tank. However, this method of operation is not only time-consuming and laborious, but also difficult to stop the operation (because the continuous inflow of sewage cannot be stopped), and the stench and germs in the tank due to long-term use , will seriously endanger the personal safety of the staff
