Problems solved by technology

In the prior art, biogas digesters are usually used in the process of pig manure sewage treatment. Due to the existence of biogas digesters, the treatment time of pig manure sewage is long and the treatment capacity is limited, which cannot meet the continuous production of a large amount of pig manure sewage treatment needs.

Embodiment 1

[0044] Embodiment 1, with reference to figure 1 , a pig manure sewage treatment device, comprising an anaerobic tank for collection, an anaerobic tank for primary filtration, an anaerobic tank for secondary filtration, an aerobic tank, a primary sedimentation tank, and a secondary sedimentation tank arranged in sequence;

[0045] There is a dry-wet separator between the collection anaerobic tank and the first-stage filter anaerobic tank. The feed port of the dry-wet separator leads into the collection anaerobic tank through the feed pipeline, and the liquid outlet of the dry-wet separator passes through The outlet pipeline leads to the primary filter anaerobic tank;

[0046] refer to figure 2 with image 3 , the primary filter anaerobic pool and the secondary filter anaerobic pool are connected together and set up with a partition wall, there is a first partition wall between the primary filter anaerobic pool and the secondary filter anaerobic pool, and the first partition ...

Embodiment 2

[0050] Embodiment 2, in the pig manure sewage treatment device described in Embodiment 1: the aperture of the filter screen is 0.425mm. refer to Figure 4 , a heating rod is installed in the aerobic pool, a thermal insulation mechanism is provided on the aerobic pool, the thermal insulation mechanism includes a sun shed and a thermal insulation cloth layer, the sunlight shed is fixedly installed directly above the aerobic pool, and the thermal insulation cloth layer covers the aerobic pool. The temperature of the sewage in the aerobic pool is maintained between 10-60° C. by using the sunshine shed 14 and the thermal insulation cloth layer 11 , and this temperature range can make microorganisms multiply rapidly. When the temperature is too low in winter, the heating rod 10 is used to locally heat the aerobic pool 5, so that the temperature of the sewage in the aerobic pool is maintained between 10-60°C.

Embodiment 3

[0051] Embodiment 3, in the pig manure sewage treatment device described in Embodiment 1 or 2: the aperture of the filter screen is 0.3mm. The thermal insulation cloth layer is composed of an inner thermal insulation layer and an outer waterproof layer; the heating rod is provided with a waterproof sleeve, and the bottom of the waterproof sleeve is fixedly connected to the mounting seat of the heating rod, and the power supply line of the heating rod Pass through the waterproof casing. A large amount of foam can be produced when the aerobic pool 5 explodes, and the thermal insulation cloth layer 11 can also play the effect of eliminating the foam when covered on the aerobic pool 5; Wires are corroded.

Abstract

The invention provides a pig manure sewage treatment device and relates to the technical field of sewage treatment. The pig manure sewage treatment device is mainly used for treating a lot of pig manure sewage which is continuously produced, and comprises a collection anaerobic tank, a primary filtering anaerobic tank, a secondary filtering anaerobic tank, an aerobic tank, a primary sedimentationtank and a secondary sedimentation tank, which are arranged in sequence; a dry and wet separator is arranged between the collection anaerobic tank and the primary filtering anaerobic tank; an aerationdevice is arranged in the aerobic tank. The invention further provides a pig manure sewage treatment method; the pig manure sewage treatment method comprises the following steps: (1) culturing decomposing bacteria; (2) collecting the pig manure sewage and carrying out primary anaerobic treatment; (3) filtering and precipitating and carrying out anaerobic treatment; (4) carrying out aerobic treatment; (5) carrying out precipitation and anaerobic treatment again; (6) carrying out disinfection and sterilization treatment. The sewage treatment device provided by the invention has the advantages of simple structure, low production cost, capability of being continuously operated, high treatment efficiency and great sewage treatment amount. The sewage treatment method provided by the invention adopts a method combining physical precipitation and filtering, and biodegradation to treat the sewage, and is green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pig manure sewage treatment device, and also relates to a pig manure sewage treatment method. Background technique [0002] With the increasing development of my country's breeding industry, pig farming has developed from self-employed farming to large-scale farming. However, with the expansion of farming scale, a large amount of pig manure will cause air pollution, and pig manure is usually accompanied by pig urine and cleaning. The waste water from the pig house, the random discharge of this waste water will cause serious water pollution. With the improvement of environmental protection requirements, the pollution caused by pig manure has become an urgent problem to be solved. In the prior art, a biogas digester is usually used in the process of pig manure sewage treatment. Due to the existence of the biogas digester, the pig manure sewage treatment time is long and ...
