Embodiment Construction

[0014] The technical scheme of the present invention is to further improve the SBR processing technology on the technical basis such as ICEAS and CAST / CASS / CASP, by figure 1 As shown, the characteristic of its technological process is that the raw water enters the ICAST reaction pool 2 formed by adding a facultative oxygen area before the SBR biochemical pool (aerobic area) through the pretreatment adjustment pool 1 for biochemical treatment, and then passes through the filter disinfection pool 6 After the reclaimed water is reused, the quality of the effluent water after disinfection meets the reclaimed water reuse standard, and the ICAST reaction tank can be operated intermittently or continuously.

[0015] The operation mode of ICAST biochemical pool is: intermittent operation: by figure 1 , image 3 As shown, intermittent water inlet and intermittent water outlet, the sewage in the adjustment tank 1 is sent into the ICAST biochemical tank 2 by the water inlet pump 7, and ...

Abstract

An ICAST method based on traditional SBR method for reclaiming the sewage in local social district includes such steps as regulating raw sewage in regulation pool, biochemical treating in ICAST reaction pool, flowing through intermediate pool, filtering in microfiltering pool, adding disinfectant, and disinfecting in the disinfecting pool. Its autocontrol and monitor equipment features that the electromagnetic flowmeter, water level relay, electromagnetic valve, and controller are connected with computer and the technological pavemeters can be automatically set up according to the quality and quantity of sewage and the DO value in ICAST reaction pool.

Description

technical field [0001] The invention relates to an ICAST treatment method and an automatic control and monitoring device for on-site reuse of residential sewage, and belongs to the technical fields of environmental engineering water treatment technology and water resource recycling technology. Background technique [0002] Water pollution and its water resources crisis are important factors restricting the sustainable development of my country's current urban community construction. Therefore, it is necessary to establish a relatively complete economical and efficient sewage reuse treatment system to truly realize the local resource and harmless treatment of sewage. Since the 1980s, foreign economically developed cities have started to establish and promote the "community domestic sewage treatment to reclaimed water and recycling system", that is, reclaimed water is used for watering greening, water system landscape, cleaning roads, cleaning cars and flushing toilets Wait, t...
