Abstract
The invention discloses a system for cultivating algae by using domestic sewage and carrying out chemical purification and processing. The system includes sequentially connected sewage treatment and filtration components for producing algae nutrient solution, and cultivation of algae by using algae nutrients supplied by the sewage treatment component. component, and the algae acquisition and chemical processing component that separates and collects the algae obtained by the algae cultivation component and supplies it to related algae processing equipment, and the algae acquisition and processing component is also connected with the sewage treatment component through a return pipeline. The biological waste produced by the algae acquisition and chemical processing components is returned to the sewage treatment and filtration components to be treated and filtered again. The invention can convert the carbon element stored in domestic sewage and biological waste into oil and other organic molecules, and produce chemical and biological products with economic value while purifying domestic sewage, which can solve the high cost problem of large-scale cultivation of algae. Promote the industrialization of biodiesel production from algae.
Description
technical field [0001] The invention relates to the fields of environmental engineering and bio-energy, in particular to a cultivation system for cultivating algae by using domestic sewage. Background technique [0002] Traditional sewage treatment consists of first-level sedimentation treatment, second-level biological treatment and third-level filtration treatment. The organic matter and nitrogen, phosphorus and other nutrients in the sewage are consumed by microorganisms. When the sewage is purified, only the precipitated activated sludge is obtained. and simple by-products such as biogas. Researchers such as Michael Wagner reported in Current Opinion in Biotechnology (2002) 13: 218-227 different microbial compositions and different nitrogen and phosphorus absorption efficiencies in activated sludge and biofilm reactors at different stages of sewage treatment. It was shown that engineered colony composition can improve nutrient elements and gas release efficiency in wast...
