Sewage resource utilization equipment and method

Abstract

The invention discloses sewage resource utilization equipment. The sewage resource utilization equipment comprises a first treatment chamber, a second treatment chamber, a biological filter and a planting tank, the first treatment chamber is communicated with the second treatment chamber; the biological filter is communicated with the second treatment chamber; the planting groove is communicated with the biological filter and is used for recovering nutrient substances in the liquid. By applying the technical scheme, the sewage treatment device has the effects that sewage is converted into a nitrogen-phosphorus nutrient solution and subjected to liquid deodorization in a manner of degrading organic pollutants to release nitrogen and phosphorus through the first treatment chamber and the biological filter tank, nutrient substances in the sewage are effectively intercepted and enriched by the planting tank and are recycled as fertilizers, and ecological treatment of the sewage is achieved. The invention further discloses a sewage resource utilization method. The method comprises the steps of anaerobic treatment, filtration, starting or closing of the backwashing assembly according tothe liquid level condition, deep degradation and deodorization, sewage impurity separation and nutrient substance recovery. According to the method, sewage treatment is simple and efficient, sewage ispurified by combining an ecological method, and resource recycling can be achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage resource utilization device and method. Background technique [0002] The current domestic sewage treatment method mainly collects through the sewage pipe network and then builds a sewage treatment station, using activated sludge method or biofilm method for biodegradation treatment. This treatment method has disadvantages: 1. A large number of collection pipe networks need to be laid; 2. Treatment The biochemical process is difficult to control, and the treatment consumes a lot of energy; 3. During the treatment process, additional deodorization facilities need to be built or residential buildings should be avoided; 4. Additional treatment facilities need to be built for the sludge and other impurities generated during the treatment; 5. The construction, operation and maintenance of facilities occupy and consume a large amount of funds and cannot achieve direct economic ...
