Movable emergency treatment equipment and process for sewage

Abstract

The invention discloses movable emergency treatment equipment for sewage. The equipment comprises a container and further comprises a flocculation tank, a sedimentation tank, a membrane tank, a nanofiltration system, a nanofiltration water tank, a break point chlorination tank, a clean water tank and an activated carbon filter tank which are located in the container and sequentially communicate with each Other, wherein lifting equipment and dosing equipment are arranged in front of the flocculation tank; a lifting pump I and a pipeline mixer are arranged between the nanofiltration water tank and the break point chlorination tank; an outlet of a sodium hypochlorite dosing system communicates with an inlet of the pipeline mixer; a plurality of ceramic membranes are arranged in the membrane tank; and a plurality of tubular nanofiltration membranes are arranged in the nanofiltration tank. The invention also discloses an emergency treatment process for sewage. The process adopts the movableemergency treatment equipment for sewage treatment. The device does not need to be assembled on site, can be quickly put into use, and is convenient to move, stable in water outlet index and suitablefor emergency treatment of sewage.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to domestic sewage emergency treatment equipment and a process. Background technique [0002] In terms of municipal planning and civil disaster relief planning, the strategic reserve of emergency treatment equipment should be one of the main contents. Taking earthquakes as an example, each resettlement site produces a large amount of domestic sewage every day. If these domestic sewage are directly discharged into nearby water bodies without treatment, on the one hand, it will pollute drinking water sources, which is not conducive to drinking water safety; on the other hand, it will pollute the local water environment, and even cause the spread of diseases in severe cases. It is not conducive to epidemic prevention in disaster areas. Taking tourist attractions as an example, their daily sewage production is relatively stable, but once the golden week, holidays, and touri...

AI Technical Summary

Problems solved by technology

The above equipment and treatment methods have the following disadvantages: 1. The activated sludge treatment method requires a long debugging time and cannot be put into use quickly, so it is difficult to respond to emergencies; (2). Because the activated sludge treatment method is greatly affected by temperature, the treatment The effect is not satisfactory, especially the treatment effect in winter is worse; (3), the conventional primary treatment methods are mostly aimed at SS and total phosphorus indicators, but can hardly control the indicators of COD, ammonia nitrogen and total nitrogen, and it is still impossible to discharge them into the receiving water body. Solve the problem of eutrophication; (4) The equipment needs to be assembled on site, which is inconvenient to move

The above shortcomings seriously limit the application of sewage emergency treatment equipment in emergency situations
