Embodiment Construction
[0014] The above accompanying drawing is one of the embodiments of the present invention. With reference to accompanying drawing, some descriptions are made to this embodiment. figure 1 It is a system process block diagram of the present invention. This is the general framework of the embodiment of the present invention.
[0015] combine figure 1 and figure 2 Gain an understanding of the process and technical system principles of the invention.
[0016] Depend on figure 1 It can be seen that the process and technology of the present invention are generally divided into four major sections.
[0017] 100 is the mechanical solid-liquid separation unit of the present invention, including: 001 sewage storage tank, 021 non-clogging sewage pump and pipeline, 002 hydraulic screen and 003 screw extrusion solid-liquid separator. Larger granular impurities such as sediment, stone, straw, hair, and metal in the sewage in the sewage storage tank are difficult to degrade by microorga...

Abstract
The invention relates to composite biochemical, coupled physicochemical, and heavy-metal-removing sewage treatment process and technology. The invention mainly discloses a continuous operation system composed of a mechanical solid-liquid separation unit, a composite biochemical treatment unit, a coupling physicochemical treatment unit, and a waste comprehensive utilization unit. According to the invention, a plant capillary biofilm bed technology, a shrub-type plant heavy metal removing technology, a flocculation complexation reaction technology, an inorganic membrane filtration technology, and optical, electrical, and membrane coupled desalination technology are adopted, such that harmful substances and heavy metal elements in sewage can be effectively removed. Treated water reaches a discharge standard, and can be recycled. Also, according to the invention, with microbial fermentation technology and high-temperature cracking technology, waste, sludge, and shrub-type plant fuel-wood are converted into nutritive soil, active carbon, tar and electrical power, such that waste is turned valuable, and pollutant discharge reduction or zero discharge is realized. The process and technology provided by the invention can be applied in organic sewage and industrial sewage treatment, and especially provides a good treatment effect against garbage leachate.
Description
technical field [0001] This patent relates to a sewage treatment process that combines biochemistry, coupling physicochemical and removing heavy metals. It belongs to the technical field of sewage treatment and is suitable for the treatment of organic and inorganic sewage with complex components, high concentration, high suspended solids and heavy metal pollution, especially for landfill leachate treatment. technical background [0002] At present, there are two problems in the process and technology of sewage treatment in my country: one is that the operation of the sewage treatment system is complicated, and the construction and operation costs are high; It is returned to nature through direct discharge or landfill, resulting in secondary pollution of the ecological environment. Contents of the invention [0003] In order to overcome the defects in the prior art, the present invention provides a "sewage treatment process of complex biochemistry, coupled physicochemical a...
