The sewage treatment equipment mainly includes structures, mechanical equipment, electrical and self-control equipment, among which the investment in mechanical equipment accounts for 80% -90% of the investment in sewage treatment equipment. Sewage treatment machinery and equipment are mainly divided into two categories: buried integrated sewage treatment equipment and fiberglass sewage treatment equipment. The investment in integrated sewage treatment equipment accounts for 80-90% of the total investment in sewage. Mechanical equipment is usually divided into two categories: unit treatment machinery and combined treatment machinery.

Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a certain water body or reuse; Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is also increasingly entering the daily lives of ordinary people; The main purpose of sewage treatment equipment is to treat domestic sewage and similar industrial organic wastewater to meet the requirements of reuse water quality, so that the treated wastewater can be reused as a resource.

Most of the existing sewage treatment equipment adopts a centralized treatment method, which cannot comprehensively and effectively filter and treat sewage. It is easy to cause blockage during the sewage filtration process, and it is not convenient for people to clean and maintain after blockage, thus unable to meet people's usage needs; Therefore, in response to the current situation, it is necessary to make improvements.

In the field of sewage treatment equipment technology, a dispersed sewage treatment equipment is disclosed, which solves the problem that the centralized treatment method of sewage treatment equipment cannot comprehensively and effectively filter and treat sewage, and is prone to blockage during the sewage filtration process, as well as inconvenient for cleaning and maintenance after blockage. The equipment includes a first treatment box, a second treatment box, and a third treatment box. The first treatment box is connected to the second treatment box by a first connecting pipe, the second treatment box is connected to the third treatment box by a second connecting pipe, the top of the first treatment box is equipped with a sewage inlet pipe, and the bottom of one side of the second treatment box is equipped with a sewage pipe; This decentralized sewage treatment equipment can filter sewage in stages, thereby improving the efficiency and quality of sewage treatment. It does not cause blockage problems during the sewage filtration process, and can effectively collect and treat filtered impurities and garbage in a centralized manner. Below, the editor will talk about the characteristics of decentralized sewage treatment equipment. Let's learn more together.

Characteristics of decentralized sewage treatment equipment

1. The secondary biological contact oxidation treatment processes all adopt push flow biological contact oxidation, which has better treatment effects than mixed or secondary series mixed biological contact oxidation tanks. Compared to activated sludge tanks, it has a smaller volume, stronger adaptability to water quality, good resistance to impact loads, stable effluent quality, and no sludge bulking. A new type of elastic three-dimensional filler is used in the pool, with a large specific surface area and easy biofilm formation and detachment by microorganisms. Under the same organic load conditions, the removal rate of organic matter is high, which can improve the solubility of oxygen in the air in water.

2. The biochemical tank adopts the biological contact oxidation method, and the volume load of the filler is relatively low. The microorganisms are in the stage of self oxidation, and the mud production is low. It only needs to be discharged once every three months (90 days) or more (using a manure truck for suction or dehydration to form mud cakes for transportation).

3. The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required. The solid-liquid separation in the pond is carried out to remove the purified wastewater.
