Shallow biofilter disc and the filtration system composed of it

Abstract

The invention discloses a shallow biological filter plate, which comprises a plate body, and a horizontal frame in the middle of the plate body has a partition plate that divides the inside of the plate body into a first section and a second section, and the first section and the second section are arranged on the left and right And the bottom of the two is connected, the first interval is divided into aerobic layer and facultative layer, the second interval is divided into filter layer, denitrification layer and anaerobic layer, aerobic layer, facultative layer, anaerobic layer and denitrification layer There are film-hanging fillers with gradually smaller gaps in the layer, water distribution pipes are arranged in the aerobic layer, filter cotton is filled in the filter layer, and a row of overflow ports are arranged on the side wall of the filter layer. It also includes a filter system composed of shallow biological filter discs connected in parallel or in series. It has short construction period, low investment cost, convenient operation, high treatment efficiency, complete functions, flexible and convenient combination, and can use low energy consumption to effectively remove pollutants in wastewater and clarify the effluent. The invention is suitable for treating all biodegradable waste water with different water quality and water quantity.

Description

technical field [0001] The invention relates to a biological filter disc, in particular to a shallow biological filter disc, and also to a filter system composed of the shallow biological filter disc. Background technique [0002] Biological sewage treatment methods have developed a variety of operating modes, and the technology is very mature. However, all current models are basically unable to fully complete all the process requirements required for sewage biological treatment, and the specific shortcomings are as follows: [0003] [0004] [0005] At present, some enterprises that produce wastewater will have the following problems if they are equipped with the above treatment systems: the required equipment manufacturing requirements are technically difficult and the investment cost is too high; the equipment layout site has high requirements for the site; the operation management requirements and operating costs are relatively High; the above treatment systems a...

Problems solved by technology

[0005] At present, some enterprises that produce wastewater will have the following problems if they are equipped with the above treatment systems: the required equipment manufacturing requirements are technically difficult and the investment cost is too high; the equipment layout site has high requirements for the site; the operation management requirements and operating costs are relatively High; the above treatment systems belong to customized non-standard equipment, with long construction period and poor response ability in the face of pollution changes

Therefore, many enterprises are currently facing the following problems when supporting environmental protection facilities: expensive equipment purchase, difficult equipment placement, difficult equipment operation and maintenance, and expensive equipment operation difficulties
