Problems solved by technology

Chemical industry parks need special sludge storage points for storage, and then process them in batches. Due to the high water content of sludge, it takes up a lot of space for storage. In summer, high temperature and high water content lead to sludge breeding bacteria. The rate is significantly increased, and the sludge is more prone to rotting problems

Abstract

The invention discloses a large-scale chemical sewage treatment device, which includes a denitrification device, an aerobic tank, a sedimentation tank, a liquid treatment tank and a sludge treatment device connected in sequence; wherein, the sludge treatment device includes: a first-level sludge treatment unit , which includes: a first shell, the upper side wall of which is provided with a mud inlet, the top of the first shell is an arc-shaped structure, and a plurality of hard brush strips are arranged at intervals on the top of the first shell; the first filter plate, which is arranged in the middle of the first shell in the form of an arc-shaped belt, one end of the first filter plate is connected to the side wall of the first shell, the other end of the first filter plate is fixed to the vertical plate, and the first filter plate The two plates are vertically fixed in the first housing to separate the lower part of the first housing into a liquid storage space and a mud outlet space which are independent of each other, the mud outlet space communicates with the upper space of the first housing, and the storage The liquid space communicates with the upper space of the first housing through the filter holes of the first filter plate. The invention effectively dehydrates the sludge while treating the sewage.

Description

technical field [0001] The invention relates to the field of sewage treatment devices. More specifically, the present invention relates to a large-scale chemical sewage treatment device and method. Background technique [0002] The wastewater discharged by chemical enterprises in chemical parks has complex water quality, high ammonia nitrogen, high salinity, and high content of toxic substances. It is a typical organic, toxic, harmful and refractory industrial wastewater. The wastewater discharged by chemical enterprises in the chemical industry park must be pretreated in the factory and then discharged to the sewage treatment plant in the chemical industry park for centralized treatment after reaching the takeover standard. In the process of sewage treatment, a large amount of sludge will be discharged, and its water content is as high as more than 97%, which is perishable. Chemical industry parks need special sludge storage points for storage, and then process them in ba...
