Weifang Integrated Sewage Treatment Equipment——Equipmentbackground

Integrated domestic sewage treatment is one of the main ways of centralized sewage treatment, which is to build sewage treatment plants in rural areas. The integrated sewage treatment equipment has processes such as physical filtration, biodegradation, and plant interception, which effectively remove organic matter. At the same time, it can achieve the goal of removing N and P through the cooperation of aquatic plants and microorganisms; Especially suitable for the treatment and reuse of rural domestic sewage, river and natural lake water systems.

Process characteristics:

① Using SNP special suspended biological fillers, the system has high sludge concentration and short residence time.

② Anaerobic biofilter: Low energy consumption, one tenth of the activated sludge process, with very little sludge production.

③ Aerobic biological filter: Short retention time to ensure effluent meets standards.

④ All equipment can use Lipu tanks or assembled steel structures, which have the characteristics of short construction period, low investment, land saving, and beautiful appearance.

⑤ Good processing effect, stable operation, small footprint, simple operation and management, and strong operational flexibility.

⑥ Low investment, low operating costs, especially suitable for small town sewage treatment plants with a scale below 2000-10000 tons/day.

⑦ The maintenance and repair workload is low, and the requirements for operating personnel are relatively low.

Process Selection

The domestic sewage treatment equipment removes floating and large suspended impurities through a grid and enters the sewage regulation tank. The sewage in the regulation tank is lifted by a lift pump and enters the integrated sewage treatment equipment. The sewage undergoes hydrolysis acidification, biological contact oxidation, sedimentation and other treatment processes in the equipment, and the effluent meets the standard and is discharged into the municipal sewer. The settled sludge generated by the sedimentation tank in the integrated equipment is transported to the sludge tank in the integrated equipment by gas lift. The sludge is concentrated, settled and digested in the sludge tank, and the supernatant is returned to the regulating tank for reprocessing together with the original wastewater. Concentrated sludge is regularly (about once every six months) transported by fecal trucks. 、

a、 grille

The grille is fixed and made of stainless steel mesh. Set up two layers, coarse and fine, to remove suspended particles and floating impurities from water.

b、 Regulating tank and lifting pump for domestic sewage treatment equipment

Due to the significant fluctuations in sewage quality and quantity, sufficient regulating tank capacity is required to ensure stable water quality and quantity entering the integrated sewage treatment equipment.

The regulating pool is equipped with a submersible sewage pump to lift the wastewater to an underground integrated sewage treatment equipment.

c、 Domestic sewage treatment equipment hydrolysis acidification tank

The hydrolysis acidification tank is equipped with composite packing materials. Under the action of hydrolytic acidification microorganisms, the wastewater in this tank hydrolyzes and acidifies large organic impurities into small molecular substances, which is beneficial for the decomposition of aerobic bacteria in the contact oxidation tank.

d、 Domestic sewage treatment equipment does not require dedicated personnel to supervise biochemical treatment

The water pump self regulating tank lifts the raw water to the reaction tank. The flocculant is added to the suction pipe (before the pump) and mixed with the impeller in the reaction tank for flocculation. The strength and reaction time of the reaction tank should be adjusted according to the different properties of the wastewater. After the reaction, the flocculated water enters the contact zone of the air flotation tank and mixes with the dissolved air phase released from the dissolved air release device. At this time, the flocs and microbubbles in the water collide and adhere to each other, forming gas carrying flocs that float up and undergo solid-liquid separation in the separation zone. The sludge that floats to the water surface is scraped by the scraper to the slag discharge tank and discharged. Clear water is collected by perforated water collection pipes and flows out from the collection tank. Part of the clean water is pressurized by the reflux pump and enters the dissolved air tank, where it comes into contact with compressed air from the air compressor to dissolve. Saturated dissolved water is transported from the bottom of the tank to the release device through pipelines.
