Embodiment Construction

[0009] It can be seen from the figure that the system for realizing this intermittent activated sludge treatment process for continuous drainage of sewage is composed of water collection well (1), grid pool (2), digestion regulating tank (3), continuous drainage intermittent activated sludge method (XUCE) ) The biochemical tank (4) is composed of, according to the reclaimed water treatment design specification, the reclaimed water treatment project needs to build a septic tank, so the B-type septic tank is used. After the sewage is collected from the pipe network, it enters the sewage treatment system, first from the sewage pipe (5 ) Go to the collection well (1), and take into account the occurrence of special circumstances such as power outages, set up an overflow pipe (6) next to the collection well (1) to ensure that sewage can be discharged normally in the event of a power outage, and prevent sewage from overflowing the ground and polluting Surroundings. Before the sewage ent...

Abstract

The invention discloses a sewage continuous drainage interval activated sludge process disposal technology. The sewage enters a catch pit and a grille pool from the pipe network collection and stay. An overflow pipe is near the catch pit. The garbage is intercepted by a buried grille pool and conducts sand setting and reducing processing via a digestive and adjustive pool functioning as adjusting the water volume, acidification and hydrolysis, and finally enters the sewage continuous drainage interval activated sludge process (XUCE) biochemical pool. The buried grille pool has four lattices and works alternatively to reach the aim of phosphorus and nitrogen removal, and removes various contaminations to make the sewage drained reaching the standard or reuse after through the disposal technology. The XUCE disposal technology is advanced, free from noise and smell, convenient in management, low in operation cost and easy in maintenance.

Description

Technical field [0001] The invention relates to an improvement of a sewage treatment process, which is mainly used for the treatment of domestic sewage, and is particularly suitable for buried sewage treatment projects. technical background [0002] The main pollutant of domestic sewage is organic matter. Now the collection and treatment of sewage has become an issue of great concern to people. Therefore, people continue to propose improvements to related technologies. For example, Chinese Patent No. CN200410017058.3 on "Integrated Domestic Sewage Ecology and Oxidation" "Treatment method" mentioned includes the following steps: 1. Sewage flows into the confluence sewer through the sewage pipe, and enters the sewage collection tank through the pump at the end of the confluence sewer; Constant flow is pumped to the top filter pool of the ecological oxidation tower; 3. The sewage in the filter pool flows down through the water outlet into the cyclone ditch where perennial wet plants...
