Chlorella-based sewage treatment device

Abstract

The invention discloses a chlorella-based sewage treatment device. The chlorella-based sewage treatment device comprises a primary reverse osmosis water purifying device, a concentrate recovering device and a treating pond, wherein the primary reverse osmosis water purifying device comprises a sewage inlet, a pure water outlet and a concentrate outlet; the sewage inlet is connected with a high-pressure pump, and a water inlet of the high-pressure pump is connected with a sewage main; a flow regulating valve I is arranged at the pure water outlet; the concentrate outlet is connected with a concentrate inlet of the concentrate recovering device through a booster pump; the concentrate recovering device comprises a casing and a reverse osmosis membrane arranged in the casing, and the concentrate inlet, a reuse water outlet and a wastewater outlet are formed in the casing respectively; the reuse water outlet is connected with the water inlet of the high-pressure pump through a water return pipeline, a flow regulating valve II is mounted at the wastewater outlet which is connected with the treating pond; a gas outlet is formed in the upper end of the treating pond, and waste gas is exhausted from the gas outlet. The chlorella-based sewage treatment device reduces energy consumption, increases the water utilization rate and has good water saving effect and purifying effect.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage treatment device based on chlorella. Background technique [0002] As we all know, water is the source of life, we cannot do without water in our life and work. The amount of water used by human beings every day is astronomical, and hundreds of millions of tons of various sewage are discharged at the same time. Sewage usually refers to the discharged water from life and production that is polluted to a certain extent; with the acceleration of urbanization in our country, At present, the sewage discharge of small and medium-sized cities and towns accounts for more than half of the total sewage discharge in the country. With the rapid development of construction, the discharge of domestic sewage and industrial wastewater will increase several times, or even ten times, which will inevitably aggravate the water environment. The deterioration of the water environment will affect ...

The amount of water used by human beings every day is astronomical, and hundreds of millions of tons of various sewage are discharged at the same time. Sewage usually refers to the discharged water from life and production that is polluted to a certain extent; with the acceleration of urbanization in our country, At present, the sewage discharge of small and medium-sized cities and towns accounts for more than half of the total sewage discharge in the country. With the rapid development of construction, the discharge of domestic sewage and industrial wastewater will increase several times, or even ten times, which will inevitably aggravate the water environment. The deterioration of the water environment will affect industry, agriculture, and various fields of people's life and work. People have paid more and more attention to the reuse of sewage purification and treatment. Various purification devices have also appeared one after another, and have produced higher social benefits and economic benefits, but most of the existing purification equipment are mechanical filtration and purification devices with complex structures and high costs
