Problems solved by technology

The main disadvantage of the above technology is that it takes a long time for natural drying, and the drying effect of sludge in rainy season is poor; the investment cost of mechanical dehydration is high, the operation cost is high, and the dehydration filtrate is often difficult to meet the discharge standard, and because the dehydration process generally needs to be added Coagulant aid, affecting the disposal of dewatered sludge
The water environment improvement that has emerged in recent years mainly adopts the construction of artificial water bodies—vegetation environments, using the principles of plant absorption and microbial degradation to solidify and remove organic matter and other pollutants in water, but the utilization of biomass energy is not sufficient.

Abstract

The invention discloses a condensed mass energy conversion pool with biological energy plant, which is characterized by the following: connecting mud condensing drying pool and biological mass energy conversion pool; setting clear water outlet at connecting part.

Description

Technical field: [0001] The invention relates to the sludge concentration treatment and biomass energy conversion technology involved in the fields of civil engineering, environmental protection engineering and environmental protection energy, in particular to a sludge that discharges waste water from water purification plants and sewage treatment plants and other slightly polluted natural water bodies It is a concentration mass-energy conversion pool that performs concentration and drying treatment and converts part of the organic matter in the water body into clean and environmentally friendly bio-energy available for use. Background technique: [0002] At present, in the design and operation of waterworks and sewage treatment plants, production sludge treatment issues are involved. Production sludge can be transported in the form of dry solids through natural drying or mechanical dehydration, so as to minimize the impact on the surrounding environment. Impact. The main d...
