Filtration purification series of two different'

Activated sludge process characteristics:

traditional activated sludge process is the most widely used city life sewage filtration purification series, the technology USES mostly by building the gravity settling basin as a means of activated sludge mixture of solid-liquid separation, not only occupies an area of big, but also produced many other problems:

1. As a result of the settling basin solid-liquid separation efficiency is not high, concentration of sludge in the aeration tank is difficult to maintain a higher level, the processing equipment of low volume load, low oxygen transfer efficiency, high energy consumption;

(2) processing effluent is not ideal and unstable, difficult to satisfy the;

3. Excess sludge production, sludge treatment cost is high;

(4) management of complicated operation, high maintenance costs.

integrated sewage filtration purification series have many advantages:

( 1) Little structures, infrastructure investment is small. Less integrated wastewater filtration purification series engineering constructions, the craft is simple, with a small investment, short construction period, the advantages of flexible operation and management, can satisfy the living community, and small and medium-sized enterprises and other kinds of wastewater treatment requirements.

　　( 2) Compact structure, cover an area of an area small. Large and medium-sized sewage filtration purification series factory covers an area of big, and the land resources are relatively short in our country, all kinds of land demand contradiction is sharpened. With integrated sewage filtration purification series can effectively reduce cover an area of an area, a lot of equipment can also be buried design, saving space, at the same time also won't for hotels, high-grade residential area and scenic landscape damage, can satisfy various requirements, has extensive adaptability.

　　( 3) Reduce pipe network construction, recycling waste water effectively. As the living and industrial water gradually increased, wastewater discharged directly caused by environmental pollution is becoming more and more serious. If will be reused, most of the waste water after treatment can be effective to save water. Due to the integration of equipment in the form of a flexible, using sewage filtration purification series of sewage treatment may be nearby recycling, not only reduces the network construction investment, but also can effectively reduce wastewater discharge.
