Embodiment Construction
[0018] A. Anaerobic treatment and post-treatment
[0019] The sewage enters the pretreatment tank 10 from the water inlet tank 12 through the grille 11, and the water in the pretreatment tank 10 is controlled by the water inlet pipe 911 and the water inlet valve 921 to enter the anaerobic reactor 20 for anaerobic reaction. In the anaerobic reactor 20: difficult The degraded matter collects at the bottom center and is controlled by the sludge discharge pipe 912 and the sludge discharge valve 922 to be discharged into the sludge post-treatment. After the anaerobic reaction is completed, the waste water enters the post-treatment primary pool 30, and the water surface is stocked with water hyacinth for preliminary purification of water quality, and the purified water is added The water in the second pond 43 is diluted, and is lifted by the pump 901 into the soilless cultivation workshop 40. This workshop cultivates vegetables, flowers and fruits without soil, and produces and harve...

The present invention relates to a cyclic economy technical system of anaerobic sewage treatment, solving the problems of the existing sewage treatment techniques, such as basic aerobic treatment modes, large volumes of aeration tanks and bacteria filters, large power consumption, large amount of excess sludge produced, big treatment difficulty, high aeration equipment price, etc. The present invention adopting anaerobic sewage treatment technique obviously reduces organic pollution sources. Most organic matter is converted to methane, power consumption and excess sludge produced only account for about 10% of those of aerobic treatment, the methane and the excess sludge can be comprehensively utilized, and vegetables, flowers, fruit etc can be planted and harvested in soilless culture workshops throughout the year. Matter is repeatedly utilized in multiple levels, converted and cycled, and waste materials are recycled, so the benefit is redoubled. The cyclic economy technical system of anaerobic sewage treatment integrates chemistry, biology, environmental protection and cyclic economy sustainable development.
Description
technical field [0001] The invention relates to a sewage treatment process, in particular to a sewage anaerobic treatment cycle economic process system. Background technique [0002] Sewage aerobic treatment technology, aeration tanks and biofilters are bulky, consume a lot of power, generate a large amount of residual sludge, and are difficult to treat. The aeration equipment required is expensive. When dealing with high-concentration organic sewage, it is necessary to use A large amount of low-concentration sewage will dilute it and other shortcomings. Contents of the invention [0003] The present invention aims at the above-mentioned deficiencies, and provides a sewage anaerobic treatment circular economy process system integrating chemistry, biology, environmental protection and sustainable development of circular economy. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] The water inlet tank is c...
